I have been reading a lot about the problem of reciprocal failure of digital cameras. Since this relates to actual size of sensels, I decided to do a quick test with my normal lens 80mm f:2.8 MAMIYA 645 AF
I just shot a newspaper at all available f.stops and processed a small crop in the center. I used one flash head on one side and removed all filters in the lens..
QUICK CONCLUSIONS
I think that f.16 and f.22 are perfectly usable apertures. Probably f.16 being the sweet spot and 2.8 to 5.6 noticeably soft.
