My hope was that the Q7's larger sensor would show less diffraction effect than the Q when used with slower lenses, primarily so that I could use a Bigma to get long reach and reasonable IQ.
The Bigma is sharpest at f8-f11 and on the Q diffraction is a problem.
For the test I set up a shot, then left the lens settings the same as I swapped bodies to try to minimize any focus changes.
The Pentax adapter was used, for the Bigma it was set to 1 (f8) and 2 (f11).
Shots were made in RAW and exported as resized JPG from Lightroom 4. Crop was done to approx 100% size, no other processing was done.
Only one shot was taken each time, I did not try a few shots and pick the best.
Maybe if I have more time I can try that later if folks think it is needed. The target was set about 75 feet away, the first shot is with 01 prime.
There is a little improvement with the Q7 that I can see, but not earth shattering. Let me know your thoughts.
Hope to try some live targets soon.
