So I was able to get to test the canon 5dsr.
Focus was quick and as accurate as 35mm dslr get. I have a Hasselblad and the truefocus is slower but more accurate.
Colors were nice, I went up to ISO 6400 and all was fine and with details. I don’t use high iso as they might be sharp in the meantime with newer cameras, but they are usualy not art when it comes to colors.
Resolution was as generally good expected. Not quite on the Hasselblad level, but at the price of the canon 5dsr it’s good value.
The Canon 5dsr is the 5ds version without low pass filter. It looks and feels like the Canon 5d mark III.
Canon AF is fast but the never as accurate as medium format.
The following lenses were tested:
- 50mm L F1.2
- 24-70mm L II F2.8
- 135mm L F2
- 85mm L II f1.2
- 70-200mm L f2.8 IS II
- Sigma Art 50mm f1.4
- Canon 100mm L
The 135mm can be sharp at f 5.6 to f8.
The 50mm L was not able to deliver sharp pictures even at f4, which was the smallest aperture I tryed and as it was no studio light, it did not make sense to close further down.
Anyway if a lense does not deliver at f4, not a lense for me.
The 24-70 (II) was surprisingly good. Very fast focus, sadly not always spot on.
If not to far from the center, f2.8 was delivering ok sharpness. Out of the center it had to be at f8. Even there it was not really tack sharp. At f11 difraction was already visible. I tested 2 lenses.
The Sigma 50mm delivers insane sharpness. I was not able to test it in Studio conditions yet.
In the field it looks like this:
Sharpening (and also noise reduction) disabled! 100% Lightroom screenshot crop.
How about High ISO?
How about highest ISO?
In general I would say it’s a Canon with more Resolution, while handling remains the same.It’s not a medium format camera, neither in resolution nor in handling. This might be a good thing for you or not. Certainly and interesting camera.
For me the results were to random, many unsharp pictures. The sensor seams to be to small with this technology and so many pixels. Autofocus is random. At this resolution you will see every mistake. The lenses are also not consistent.
