Sensor shift in the New Olympus EM5 Mk.2.


The refresh of this v. successful model by Olympus will be introduced in February, so all I have is some rumors. Movie rate, EVF, many of the features introduced by the latest Olympus models will be there, but the killer feature will be sensor shift (SS).

So far we know v. little: that it takes 8 pictures byf the sensor by 1/2 pixel, and achieves an image of 40 Mpx. We also know that IBIS stabilisation works in a bracket of 5 pixels . Since  1/2x8 = 4 pixels, so my bet is that sensor shift will happen as part of IBIS, with no need of a tripod.


By my early experience with a superresolution program called 'PhotoAcute' I know that you must slightly shift an image after the first so the program can compare pixels, and increase the information as a result. The program, created by a Russian mathematician,  was v. processing intensive, since each pixel of the preceding picture had to be compared with each of the following one.

Thankfully camera processing power doubles each year, so presumably each 8 pictures can be compared in a reasonable time, seconds instead of minutes.

We also know that the 'old' E-M5 could shoot at 10 fps, so again 8 frames can well be taken  within just one second.


The old E-M5 'Its going to be redesigned anyway.

I assume that stotal shutterspeed of the 8 frames shouldn' be more than one second: shutterspeed defines how fast the objects in front of you can move, fluttering leaves in a windy day being the typical problem for the landscapist. The other problem is people moving through the landscape, but freezing that  should be well within the capacity of the new system, provided one operates in fair weather.

What is the rationale for SS? First you don't need to change system anymore to have v. high definition. You don't even need to change lenses with more resolving ones, since the process is sequential.

At any rate the feature is excellent news for landscapists, portrait and macro users, down to PJ. An Editor is always happy to crop pictures (and a noob too).

People are asking if there will be less noise and better colours. Going by PhotoAcute, I'd say that the colours stay the same, but noise is filtered, while the sofware compares pictures.
A user also advocated more Dynamic Range a' La HDR.
But I'd rather bet that exposure is determined by the first shot and doesn't change for the following 7. The opposite would be a loss of time. So HDR will stay a separate feature, like it was in Photoacute.

BTW the E-M5 already has 12 bits of DR, so it's more than enough. Introducing more would mean to lessen the contrast and having flat pictures. Same goes for colour, it probably stays the same of the first picture, so what you earn with SS is really more detail and less noise.

All this was based on a pure deduction a la Sherlock Holmes, (!) but it might be v. different of what Olympus' engineers have concocted. Then wait for February and check how much of this set of assumptions is wrong :)

To me staying with one system only, and only one set of lenses is a remarkable advantage, and SS has stopped me in my tracks while taking an interest in Sony's A7 and having a fit of GAS. So well done, Olympus, with your 40 Mpx! My wallet is grateful...

When you are able to dabble with single pixels, small sensors still have the advantage. Less processing to do, quicker reactions of the camera.
Olympus' genius is to have designed a superresolution device working within IBIS, and therefore avoiding the need for a tripod like the Sony A7r is reported to need.

Now to recap: Sensor shift must work within IBIS.  IBIS shift works within 5 pixels. If so 1/2 px x 8 frames = 4 px, well within IBIS.

EM5 also has a fast 10 fps so all could happen within a second. With a new double speed processor integrating the eight shots shouldn't take more than a handful of seconds, like an Art Filter.The result is more than twice the resolution and less noise.

The Pen Light Saga

Detail of the Olympus E-PL7, with the lovely 17/2.8 pancake.
The first annoucement to anticipate the coming Photokina is the E- PL7 by Olympus. It has been dubbed the Selfie Pen, for its tilt down screen, allowing an optimal, plunging angle of view. The sensor is the by now unremarkable, but excellent 16 Mpx sensor that has been gracing Oly for the last three years. It has almost 13 stops of Dynamic Range,  25600 sensitivity limit, and a per pixel sharpness that rivals Full Frames like Leica.

Please see two excellent reviews here:



However the real news is for the Europeans. While the PL7 with kit will cost $ 700 in the US, ilt will be only € 499 in the EU, this reflecting the true exchange rate - a first however for Olympus.



The E-PL7 with selfie screen. Note the pancake zoom, and the second wheel around the shutter button, under the index. Body only the camera is € 399!

This reminded me that  the PL1, the first of the saga, was my first buy into m4/3 and mirrorless, some 4 or 5 yrs ago (how time passes!) for € 350. Before that the Pen line had been an unapproachable € 900!

Additionally it had a plug for an EVF, which changed completely the useability of the little one. Yes it was also much smaller, it came only in black like the Ford T, and it was with it that I began the joys of Street Shooting, nobody taking any notice of the little 'toy' sized camera.


the E-PL1. CC by Benoit Marvhal. The Ugly Duck, now in Silver :)

The PL1 was a big success, followed by the PL2, PL3 (I had that one too) all 12 MPx, and then followed by the 16 Mpx PLs.

The Pen Lights rested on a paradox. Designed for P&S, thy had a secret software switch, which made them  serious second cameras, by showing the full configurability of the camera in the menus.

They rested on another paradox. While marketed in the West as Volkscameras, Cameras for the People, they were bought by adventurous males - but in fact they had been designed in Japan, especially for Camera Joshi, the Girls with A Camera!
I tried to divulge the notion but it was v. poorly received by Western machos at DPR  :)

Whatever, today the Pen Lights are the mirrorless top sellers in Japan, and by now I can hardly walk in Rome without seeing a Camera Joshi tourist with one!

A couple of months ago I bought an E-PM2 (for a paltry 150 Euros!) which is the smallest of Oly, not even having a tilting screen, although it has a touch one.

In the recent Pen Lights you can also focus in any point of the screen, and focus/shoot by touch. Priceless! (E-PM2)

Fact is that it has the same 16 Mpx of my Queen, the E-M5, but it is really pocketable, therefore I use it much more!
Even, the PLs suggested me a series called 'Citizens of Rome', based on my shooting blindly from the hip with one of them, and thus becoming the Invisible Man.



Behind its desultory, but shiny appearance, the E-PL7 is a dragster of a camera. It has the fastest AF in the Industry and a pancake 12-42 which is prodigy of design. It has  3 axis IBIS stablization, meaning that your old adapted MF lenses will be stabilized too. It shoots at 8 fps. It has good movie speed at 30 fps, with 3-axis stabilization making it a breeze even without a tripod.

And last but not least it has an array of Art Filters that will allow you to pre-program the camera in all the crazy ways that photographic ingenuity has designed over time.
My favourites are the Pin Hole, like the piccie above, and the Dramatic Tone B&W:


The two new filters the PL7 adds to the array are Partial Colour, and Vintage, resembling Snapseed and Instagram.

In the next episode, I'll review the GM5, which is the Panasonic equivalent of the Pen Light.

It will have the big advantage of a built in EVF, and silent electronic shutter. We'll see however how big and expensive it is. People around the Web are protesting that it might be a replacement for the well loved but bigger GX7.  Unfortunately GX7 sales were spoiled by the OM-D series by Olympus. But Panny might still take a vengeance with the diminutive GM5.

This leads me to  a last consideration.
Smartphone sized, WiFi, connected little cameras are replacing the old dSLR paradigm. Size is not anymore a guarantee of quality. Even, smallish might become not only the trendiest, but also a synonym of the best quality: the true Leicas of the XXIst century.

Camera Joshi discovered it years it ago: Light comes from the East :)

Settings

Here is how I set a Pen Light. First I activate the Super Control Panel (SCP) from the Menus:


This gives me a matrix of controls that I can activate by touch. In P like Program, I leave the defaults, except that I choose Auto ISO, and Center Focus.

Secondly, I usually set the camera for high or low contrast days. This entails correcting  EV for Brightness, and/or setting Auto Gradation, instead of 'Norm', for relighting plugged shadows.

 I also made a preset B&W with high contrast and orange filter.

If I want to go into WoW! territory I use B&W Dramatic tone, or if I am moody, Pinhole or other Art Filters.

Oly's colours out of camera are extraordinary, and I was regularly losing them when doing RAW, so I went back to Jpeg. I am told the same happens with Fuji, and its Film Simulation modes.

I can now activate or not the 'Keep Warm Filter' from the Menu, according to the season. And I can fine tune the WB according t the light, if it's warm or cold: there are may presets, and you can devise yours.

So as you see there's a lot of interpretation allowed even by using the camera controls. You can do all at the scene, and compare with your eyes, if they fit.

Of course I aim to maximum resolution, and can consider increasing brightness to the limit to lighten up shadows, but basically I am after quick content, so I usually rely on auto exposure (ESP), and change settings only after a set of shots, not to create tone or colour discrepancies.

I usually shoot in Jpeg Super Fine, but of course many will be happy to use RAW, or both.

If you are into landscape, don't forget that you can add a VF-4/3 to any Pen:

This 2,36 Megadots beauty should cost you around $ 250 (€ 200?), but you can carry it across bodies when you change cameras. It will show you all the tone subtleties and details of a Landscape. Note that in the menus there is a Tone Control Curve, that can be split in two, for better effect.

Don't forget that by activating the built in  WiFi you can duplicate the camera picture, and use some same controls in your smartphone, as if the camera was tethered to it.

And you can instantly send a Jpeg from the Artic to your friends, if your ship has WiFi! Think a Selfie in front of an Iceberg :)

Enjoy!

Wearable Glass and 360° vision.


Disruptive technologies have a way to get through from SciFi to market success in a few years, witness mirrorless cameras.

A few observers forsee the same for Google Glass, the wearable device getting mainstream this year : shall we kiss goodbye our smartphones? I would shed no tears. This is an preliminary article anyway: we'll see how things pan out. For the moment this is more an inventory of links, than an assessment, but I have no doubts that wearable technology is already taking long strides.

For the moment universal use seems hardly likely, except for the affluent, with Google Glass selling to a selected few at $ 1500  as part of the Google Explorer program. Google has just expanded to Britain the Explorer Program,selling the Glass for UKP 1000, offering in the meanwhile  new  glass frames that could be compatible with prescription lenses in the UK.


Here at Wikipedia the last specs:


What drew my attention however is the appearance of a Chinese clone , the SimEye.
 At $500 it seems far more reasonable. The difference is in the number of app offered, and the fact that it doesn't respond to voice controls like the original, and has no sound transmission through the skull bones like Google. But it can still take photographs and record movies with 4 times the definition of Google. And it can still download apps directly from Google Android Libraries.
Would that be able to interface with one of my cameras?

Photo Wang Yin Hao


Looks a bit unsteady. Note that Google mentioned recently that the final price to consumers of the Glass would be close to your average smartphone - so better wait!

Meanwhile Olympus published a patent for wearable glasses, and I later discovered it is associated with Kopin company for development of a new device.
Olympus is known for its world dominance in endoscopes and medical devices, so Medical could be the first application. But it could also go consumer:



Note that the device can be disassembled, which is not true of Google Glass.


Imagine surgery with augmented vision, a thing that military jet pilots already have with their headup displays in their helmets. But here the device is much lighter and less intrusive.
It could also bring augmented reality to the operating table: a surgeon could  see a heart in 3D:


Or could it go Consumer and Virtual? Virtual Reality quit consumer markets some ten years ago because it required some extremely fast and expensive computers to be credible. Therefore it was the preserve of training devices for the military, like jet plane simulation. 

It is now making a comeback to consumer games, because of the fast increased computing power of miniaturised devices, and their high resolution screens. Also, Wi-Fi and Cloud can act as Storage.

There are out of the box solutions, making use of devices you might already have. Check this, the Oculus device for making a Samsung phone into a virtual reality device:




By sliding a phone into with a wearable box with two magnifying lenses, you use the high definition Samsung screen to input software provided by Oculus, the Facebook funded company. 
The built-in lens of camera phone also allows to superpose the artificial and the real. Remarkable!

The main reason reason however for me to take an interest, is that Olympus mentioned wearable glass a a future interface for cameras. Imagine a WiFi link between camera and Glass, instead of using a smartphone. Wouldn't it be more natural in the long run than sticking an odd, and expensive EVF to its Pens? 

Google Glass was not born for Photography though. "It's a pretty crappy 5MP cell phone camera - there's not much else to say. It's ok when you have some sunlight and a muddled mess when you don't." says AndroidPolice


First you say "Show the viewfinder", then "Take a picture". Here are the main voice commands:



The most successful apps at the moment  include a Moving Map indicator, which can tell where you are, and direct you through the road system. You input the data with your voice. "Get directions to..." will fire up the app and start navigation to your destination. Just like your phone on Android, you can direct it to a specific business, search for a type of business, or speak a whole address.

You also have the regular Google Search, although presentation of the results by Cards, makes it somehow messy and laconic, says AndroidPolice.
Certainly you can also dictate an e-mail and send it with a vocal command to Gmail. By the same token it is easy to send the images you took with the 5 Mpx Glass to Google Galleries (Picasa?). You can also do short bursts of 720p.


Another  app being developed will help you speed up check ins at British airports, another will act as a guide to the Sixtine Chapel, the Egyptian Museum of Turin, and other Italian museums, by using facial recognition on the mummies, or the paintings! It is difficult to tell however what is already there, and what is just planned. Will it also be able to translate presentations and street signs? Or even pick up a conversation in Japanese and translate it?

Meanwhile Photography  got me interested in a crowdfunding device that will soon hit the market: the Bublcam:




This camera is the size of a baseball, and has 4 lenses that cover 360°. It was designed in order to allow  iimage swipng  across a smartphone. Proprietary software allows to stitch the 4 images in a circular image, which covers all of your surroundings. 

If that was linked up to am Oculus device, imagine the immersive effect! Perhaps we are at the verge of  blending natural vision and machine one, in high definition. Have a taste here:




To have a further idea yet look at these 360° pictures of the Mundial and its stadiums in Brazil, by photog. Henri Stuart. You can swipe to your heart's content. Here the post:


and here, choose one of his  pictures, and swipe it !:


There is already a minor alternative to bubl, the CENTR:




So are we finally overcoming the limitations of the frame? Frames were invented in Europe just before the Renaissance to allow merchants to have their portraits made,  bought and carried away. But long before that painters were paid by bishops and abbots to make  frescoes of the Saints  covering whole walls of Churches with visualizations of the Bible: far more immersive. With 360° cameras we are back to the beginning.

What will happen to Photography, as we knew it,  will it stand a chance? It's rather traditional cameras that are in danger, I am reminded about Marcel Duchamp's words about the camera some day becoming as outdated as Painting. 

Note that according to a specialised site, Optical Vision Site there are 39 companies  flexing their muscles in the new Wearable Viewer market and that sales have doubled every year:


Meanwhile imagine to hold a Bubl ball in your hands high above your head, documenting your surroundings for your wearable glass, and uploading them by WiFi to the Cloud.  In California a journalism course has been already lauched based on Google Glass.

It would certainly change holiday photography, and a lot more: it would be an experience akin to Life-Logging. You could blend your images of monuments and temples with those of other users.

Sometimes I am scared by such an intrusive future coming soon, and yet I welcome the Glasses as a more interesting viewing device than a smartphone. Imagine the prices were similar. If I had the choice, I would go for the Glass, since it can take and make calls too anyway. And you, what would YOU prefer?



Much of this bounty however will depend on available app in the Android ecosystem, and the development of more powerful  batteries. So far Google has kept strict control on third party applications, but these are early times. 
The Battery allegedly lasts 1-2 hours. Needs more juice, to become your permanent wearable computer. So far it just shuts down like an ordinary phone. But it wakes up if you nod 30° upwards!

Google Apps are updating at a monthly rate, so chances are that you won't recognize your Glass after a few months. it's a kind of Transformer thing.

Photokina is now looming: we'll see what comes up then. Or perhaps Photokina being more a more traditional camera show. the new consumer devices will emerge beginning of next year at CES in Las Vegas? 

Will traditional cameras stand the attack, or is it the beginning of the End? Smartphones are already nibbling at a 20%  yearly rate at camera sales each year worldwide, according to a preliminary Photokina's report. Glass might be the kiss of death, unless Olympus develops itself a wearable device specific for cameras.


Note however that mirrorless (ILC) is faring better:



There are however some no-nos about wearable glass. You don't wear it near restrooms, lest they take you for a voyeur. But if you want the full criticism, have a look at the 35 arguments against it:


Some arguments are quite wacky, and luddite.  Other concerns are quite real, basically about privacy and the use that Google might do about your personal data, that you must input in the device in order to make it work.  For instance there's a difference between using anonymously Gmail, and inputting your real name in Google+. Google would like to feed the Contacts side with real names, if only for the sake of brevity.

However petty criminals  could use the device to blackmail unaware celebrities, although paparazzi did that  already there with their plain cameras. But with Glass, how can people tell if you are shooting them or not? Also don't forget that you have Google Search at your fingertips in the Glass. You can actually be guided to a person or a shop!

So there are also etiquette concerns of all kinds - smart restaurants refusing use, and safety issues. Although freeing both hands you can't superimpose virtual reality to what you are driving through, without risking an accident, because of the different planes of visualization and attention. Is it why Googles is introducing automated driving? The application is there, but  it is not yet legal. Both the US and the UK have prohibited driving  while wearing the glass.

 Glass  will make the wearer feel like an omnipotent  'photographer' with the Third Eye,  always at the ready for a shot, by a vocal command, or even a discrete tap on the touchpad of the frame. But will he/she be a photographer or just a camera wearer?

I am particularly interested in user experience. How often do you use it?Please feel free to use the e-mail module here affixed. Other users of this site could also comment if they find the new devices desirable or not.
More importantly, do you think that this mode of visualization, this mingling of the artificial and the real, will be the end of cameras, if not of Photography?

The Daily Telegraph just announced the opening of an Amazon shop in Britain dedicated to wearable technology, and it published the latest market forecasts:

"Wearable technology has already emerged as one of the top tech trends of the year. Deloitte predicts than 10 million wearable devices will ship globally in 2014, from sophisticated gadgets to smart textiles and skin patches.
In a recent survey of 6,000 individuals by consulting company Accenture, 46 per cent expressed interest in buying smartwatches, while 42 per cent said they'd be interested in purchasing internet-connected eyeglasses, such as Google Glass.
The global market for wearable technology was reportedly worth $2.7 billion (£1.6bn) in revenue in 2012 and is expected to reach $8.3 billion (£4.9bn) in 2018."


Finally you could control Glass and shoot pictures, even by mind control, i.e. concentration, by associating Glass  to an EEG reader through an app, called MindRDR



Don't believe? See this fascinating article here at BBC:
"An EEG headset can be used to measure when certain parts of the brain show a greater level of activity.
In this case, the MindRDR software monitors when the wearer engages in high levels of concentration.

Within Google Glass's "screen" - a small window that appears in the corner of the wearer's right eye - a white horizontal line is shown.

As a user concentrates, the white line rises up the screen. Once it reaches the top, a picture is taken using Glass's inbuilt camera."

Please check the BBC video, to see how the thing works, it's amazingly simple. To send a piccie you just think the same thing twice, and the picture gets sent to a pre-programmed address.
The thing is meant for paraplegics and people 'walled inside' and it's really a hack, not recognized by Google.
But who knows, one day you could take a pic by thinking deeply about your mother in law. Never say never :)

Olympus in-Camera magic: the OM-D series,

(Warning! Contentious content)

Some people are used to give female names to their camera. I don't but if I had  to, i would give it Mélusine, the name of the Queen of Fairies, with the tail of a Siren, so well she supplements the needs of Imagination.

When the E-M5 appeared almost 3 yrs. ago, the mirrorless m4/3 format was still immature: slow AF, mediocre sensor, low sensitivity to light, restricted Dynamic Range. All it had was small size and better image quality than the so called Point & Shoot cameras.

Then suddenly all problems were solved, everything fell into place, and we had a jewel of a camera whose whole was more than the sum of its parts. When Steve Huff made one of his Strange comparisons against the Leica M9 he defied his audience to tell which shot was which.

The E-M3, a black beauty.

To me its is still a recent buy, but from the beginning it has somehow changed the way I shoot. By offering a tolerable EVF of some 1.4 Mpx and a small dSLR form factor it brought me back to my film times. But by giving me separate wheels for aperture and EV controls, plus a manifold of buttons to change the settings it has made for me even more useless Photoshop and PP. DPReview however was the first to notice that Olympus had made the miracle of making a Jpeg processor which had as good Dynamic Range as the best result you could get from RAW processing.

I know that many will cry foul. This is a contentious issue for people who consider Lightroom their holy grail. Much good might it do to them, I consider the time saved in avoiding PP precious for further shooting.

By seeing what the sensor sees I make corrections on the spot, and I am ready to shoot in a few seconds, even with the right Art Filter if I need a special atmosphere, for tone gradation there is even a separate button.

The OM-Ds have also a nice feature called Live Time. When shooting at extra low shutter times, the camera shows you an image emerging from the screen, so that you can stop the exposure any time, when you are satisfied with its brightness. Live Time makes it easy tomake such effects, like light-painting:

courtesy Steve Huff.
On the side of reactiveness,  not only the AF is lightning bast. The back screen, a great bright OLED  is touch sensitive, and has touch shutter: you select the area AF by touch, the camera does it and shoots instantly.

Priceless: when using it from the navel, people never notice you, especially if you have a wide angle pointed in a different direction, but they are still within the frame. OTH you can completely shut down the back screen, and use the EVF instead, as if it were an ordinary dSLR: great in bright Summer days, and great on batteries.

Now about the debate Jpeg vs. RAW. The difference is not in the recording format, but if and when you do a photographer's work. You are not collecting Kellog's Mickey Mouse piccies like kids after all, are you? One must be ready to catch reality, and if that reality is dead, because it is PAST, no exotic processing is going to save your skin.

Reality must be caught while it develops. That is the meaning of HCB apocryphal: 'I am a  hunter, not  a cook'.  We are not Digital cooks. If need be, one can convert an uncompressed  Jpeg into a Tiff, and work losslessly for minor corrections. Don't invent a fake world at the expense of a snap!

With the OM-D Olympus gave the possibility of preparing a perfect image BEFORE the shot, which a photographer should always attempt. Thinking that one will save the image later and correct it is just an illusion - treating photography as if it were  a painting, adding layer upon layer, an additive art, which it isn't. Better choose the right light on the scene, instead of brightening later on the computer. At the worst learn to use a speedlight - you are still using real light! Photography is about Light, not about layers of painting.

A proof? If you have a high number of keepers from the start you won't be interested in spending hours in the digital lab. You'll be more interested in spending that same time on the field in catching the visual opportunities. And this will result in a higher number of keepers.

Now what is a keeper and what is not a keeper? If you are on flickr, you know that others will rate your pics, and  that they almost never rate the camera, or the processing, but content, the decisive instant.

They will be indifferent if it is a Jpeg or a Tiff, and they will certainly not rate a RAW. They will rate if the picture is timely or not. The same will happen in contests.

All this wouldn't have happened if Olympus and Panasonic hadn't introduced the view from the sensor instead of the traditional dSLR view from the lens. EVF allows WYSIWYG and it is the whole difference: like going from a geocentric astronomy to heliocentric. You compose everything  on the LCD. Bye bye, Photoshop!

The E-M1 was the first to sport duplication of functions by WiFi on a  smartphone.

Now back to the Olympus cameras. Later models have refined the concept and added innovative features.
The expensive E-M1 introduced PDAF in addition to CDAF (Phase AF + Contrast AF). This allowed to use over 30 High Quality lenses of the earlier 4/3 system and use them at their native speed, which had been impossible with the E-M5. 
  It added also HDR in camera and Time Lapse Movies. A Color Director - I could also see its uses, next to Tone Control. Again something you don't need Lightroom for anymore

Introduced later this year, like in the E-M1, the economy E-M10 added Wi-Fi, which allows to download, or better upload piccies to your favorite social sites on the fly.
The E-M10 sports a new pancake zoom kit lens

Thus you can see a new concept emerging in photography: not  a work of art or better an overprocessed monster, slowly cooked in PS, but image as instant communication, to be corrected later in Instagram or Snapseed if need be, if you want to add to the fun. Otherwise just plain, stark photography, directly uploaded on line. Communication first, musings later.

Besides WiFi also allows to literally to drive the OM-D on a tripod from the phone: again WYS in the phone is IWYG from the camera. Isn't it neat? You can 'touch' the camera from the phone!

Another feature all those fairy cameras have is strong IBIS, meaning that you have rock steady AF, a thing that only steadycams could provide in the past, with a heavy expense and with a cumbersome equipment. Now it works with a slight buzz, as if by magic. Or the whirr of invisible gyroscopes. In fact Olympus made the sensor levitate!

 That means shooting with a 3-4 stop advantage in low light. You can also shoot movies, which are absolutely steady, including the image of the viewfinder.

This combination of features has resulted in an industry standard that other brands have trouble to follow.  This disruptive  technology has created a cognitive gap with other users, that is why I have trouble explaining why I am not interested in Photoshopping anymore and I have switched instead to  the 'Slow Photography' paradigm.

When I tell DPR forum users the above they can get very angry, but that's the mere truth: disruptive technology can change radically one's habits, and sometimes for the best.

I have been accused of using Olympus' Art filters in place of PS, in a crude way. But the truth is that I like them crude, exactly like B&W is a strong transformation of colour. I like them not for realism, but from distancing from the real in a critical way. For instance to show how hard underprivileged environments can be. I am not into the beautification of marriage photogs. or other commercial shooters.



A tip about the lenses

Strong IBIS and good sensors have much reduced the need of fast lenses - this is another contentious argument. Be against or for, my pleasure. But I will give my opinion:

People have forgotten than in film times there were plenty of 2.8 and even 3.5 great primes optimised for resolution and small size. Last century. Leica 3.5 lenses were not rare, and so Zeisses and other wonders: the best pancakes ever made for rangefinders.

Lenses below 2.0 were rare, big and mostly used for Portrait or Fashion. Now in the consumerist age everybody seems to have learned the worst from Marriage photogs. , but the truth is that fast and sharp exclude often each other. 

Example: the PanaLeica 25mm has half the resolution at 1.4 it has at 2.8, Lensrentals discovered.

So people get lenses that are fast and sharp, but only at smaller apertures, and pay big bucks for the privilege, LOL.

Zeiss knows since it just provided the Sony A7 with a 35/2.8 for small  size and sharpness.

But what do people know? In fact with short distance to flange it is v. risky to make fast lenses, especially in wides, for resolution drops at the edges since they are not telecentric.

Better have a moderate aperture and exploit the sensitivity of the sensor, exactly like Sigma is doing with its Art DN Series, if one wants sharp across the frame. These lenses are resolution champions  for Micro 4/3 and they cost 1/3 than those of other makers. Just check them at Lensrentals.

The Sigma Art Series for m4/3 system, all f/2.8
BTW sharp and high resolution are not the same. Sharp is subjective while resolution is measurable.

Most of my lenses are 2.8, and believe me I don't feel limited at all. In low light Auto ISO can to to 3.200 or even 6400 and IBIS allows me to shoot at 1/10 s perfectly stable at 2.8. What else do I need? That is candlelight.

People object: but you don't get nice bokeh. I reply get close to your subject and you'll have all the bokeh you need at 2.8. 

Besides I, consider bokeh  a dirty trick issued from the beautification drive of Marriage photogs.  - a drive towards fake photography as fake as it might be. Women without pimples or freckles.

Again this has nothing to do with Slow Photography, which is rather on the side of f/64 and the Stieglitz camp. Again YMMV, as they say. But a Camera is first and foremost a perspective machine. Why waste your DOF by blurring everything?

Feel that I have been unfair or unjust towards PP? Feel free to comment. If we are many we might even try to make a poll.

My Black Queen, with gaffer's tape over the Logos.
