LEICA SL2 WITH 187 MEGAPIXEL RESOLUTION

 


By Heinz Richter 

 

When Leica introduced their mirrorless camera flagship, the Leica SL2, it came with a resolution bump up to 47 megapixels.  Thus Leica had an answer for those that felt Leica was beginning to run behind in the megapixel race. 

 

However, 47 MP is just the beginning.  The SL2 now is capable of an astonishing 187 MP.  Leica released a major firmware update which allowed photographs with a resolution of 187 megapixels from the same sensor with a new multi-shot feature. 

 

According to David Farkas of Leica Store Miami, the camera takes the already impressive single-shot 47 megapixel resolution of the SL2 and, by capturing a series of eight exposures in rapid succession, stitches them together to create a single, mind-boggling 187 megapixel DNG file.  To do this, the camera repurposes its in-body image stabilization (IBIS). Instead of moving the sensor to counteract motion and reduce camera shake, the sensor is shifted by mere microns to record ever so slightly different images. When all eight shots are combined, the resulting 187 megapixel images display a staggering amount of image detail. 

 

There are a few caveats when using the new multi-shot feature. Because the IBIS mechanism is being utilized for pixel shifting, all image stabilization is disabled. Also, only full frame lenses can be used, so TL glass won’t work here. Other restrictions are that the maximum ISO is limited to 3200, the longest shutter speed is capped to one second, you can’t use strobe, and electronic shutter is always used. All of these make sense given what the camera is doing during the capture process. And of course, you’ll want to be locked down on a sturdy tripod and shooting a non-moving subject. In fact, if you’re not on a tripod, the camera will detect movement and display an error message.

WHAT’S IN MY CAMERA BAG AND WHY




By Heinz Richter

A while ago I published a brief article showing what Leica equipment I own and use.  I constantly get asked what camera and lenses I have and why I chose them.  So I decided to be more specific. Please keep in mind this is not meant to influence anyone to invest in certain equipment, it is simply an explanation of what I own and why.

My first digital Leica was a Leica Digilux 2.  I bought it because it had a performance level at that time that was able to do a lot of the work that previously I had done with film.  Of course things have progressed substantially and I now shoot with a Leica M240.

I am fully aware of the advantages of the Leica M10 and M11, but they are not at a level of importance to cause me to change.  The M240 is serving me well and will do so for some time to come.

For instance, the larger size of the M240 does not bother me at all.  As a matter of fact, for some time in the past I used a Zeiss Contarex.  The M240 is rather diminutive in comparison.

At times the higher ISO capabilities of the M10/m11 would be nice to have, but I hardly ever use or publish any photographs that have not been improved by post processing.  That includes the higher noise levels of the M240 at high ISO settings.  Subsequently, the higher ISO capabilities of the M10M11 are not overly important to me.  The M10 or M11 don’t offer enough of an advantage for me to warrant the expense of switching.


The obvious advantage of a camera with interchangeable lenses lies in the fact that, based on the work one does, it is possible to choose a lens that's best for the job at hand.  In general, that includes the so-called normal lenses which give a field of view closest to the human eye.  For full frame (as well as 35mm cameras) that is the 50mm focal length.  From there, anything with a shorter focal length is considered a wide angle lens and anything longer is a telephoto lens.

The core of my lenses are a 28mm f/2.8 Elmarit, a 50mm f/2 Summicron and a 90mm f/2.8 Elmarit.  They are excellent performers and have not given me any cause to change them.  Would it be nice to have faster versions of these lenses?  From time to time yes!  The extra depth of field control and bokeh of a 90mm f/2 or 50mm f/1.4 would come in handy from time to time, even more so with the the 50mm f/.95 Noctilux.  But not to the extend to cover the extra cost.

I mentioned already that the limited high ISO capabilities of the M240, when compared to the M10 and the M11 must be considered a handicap. However, with noise reduction it is possible to use the M240 with ISO 4000 and even 6400 and obtain acceptablwe reults. Just don't expect these settings to render anything useable without post production work.

I have been asked if a 35mm wouldn’t be worthwhile to have.  I admit that I have often thought of adding that focal length.  But the 28mm Elmarit performs so well that I have no problem cropping a file from the 28mm to obtain a narrower field of view, including that of a 35mm.   I rarely, if ever, make real big enlargements; this allows me to use cropping with all of my lenses as a tool to overcome one or more missing focal lengths.  As a matter of fact, cropping has allowed me in many instances to overcome the fact that for a rangefinder camera like the M240, zoom lenses are unfortunately not available.

At the far end of the lenses I have are a 15mm f/4.5 Voigtländer Super Wide Heliar and a 135mm f/2.8 Elmarit.  I bought the Voigtländer because occasionally I run into situations where the 28mm is not quite wide enough.  But these occasions are rather rare and thus did not warrant the expense of a Leica lens.  The 135mm Elmarit on the other hand is a lens that I do use fairly often.  Much of my work is portraits or portrait related.  A lot of people that are not used to being in front of a camera on a regular basis are often quite apprehensive.  For closer shots, like head shots, I found it to be quite advantageous to use the 135mm instead of the 90 or even more so the 50 because I can work at a greater distance which can put the person in front of the camera more at ease.

On and off I do some wildlife and close-up work.  Some time ago I picked up a Nikon 55mm Macro Nikkor and a 105mm Micro Nikkor.  They sat around until I got the M240.  With the electronic viewfinder and a Nikon to Leica M adapter I have two rather well working macro lenses that serve me well.

For long lens work I use a Novoflex 200mm f/3.8 and a 400mm f/5.6.  I was able to pick both of them up for next to nothing and I have found that they are equal or at least very close in performance to equivalent Leica lenses.  Especially the 200mm has an amazing performance potential.  That seems to be partially due to the fact that both lenses are of the same design as the former 400 and 800mm Telyt lenses from Leica.  Another reason was the ease of focusing of the Novoflex Follow Focus lenses.  Unlike any other lens, they use a spring loaded pistol grip for focusing.  Releasing the grip will set the lens to its minimum focusing distance.  Squeezing the grip will focus to infinity.  Once used to it, this has proven to be very fast.

Yes, it's a lucky shot

Would another camera system be something for me to consider?  I have toyed with the idea of a Leica SL.  But when I think back to the days when I used a Leica R3 and R4, I feel that just like then, sooner or later I would gravitate back to an M camera.  I started out many years ago with a Leica III.  I guess that ultimately made me a rangefinder shooter.  I may add another camera at some time in the future, but I will always have a Leica rangefinder system at my disposal.
