Samples from ISO 125 to 1600 are available. Besides, the "01" standard prime is tested from f/1.9 wide opened to f/8, in 1/3 steps. Key EXIF info are reserved.
A few selection of the more representative ones (Click on for FULL Photos):-
(ISO 125, 8.5mm, f/8)
(ISO 125, 8.5mm, f/2, f/4 & f/8)
You can see by yourself if diffraction is a real problem for limiting resolution with such a small-sized sensor.. (Hint: Look at the image centres for the word "LUPICIA" and Compare!)
So, one BIG question for the implication: Do the Q users need to stop down the lens during a bright day in order to make proper exposure for their photos?? :-o
(ISO 1600, 8.5mm, f/2.2)
(ISO 500, 8.5mm, f/2.2)
