Originally posted by Lloyd_Christmas Hi all,
I'm curious about any negative effects of using full frame lenses on APS-C body.
Since the image circle is larger where it hits the sensor, is there extra light perhaps reflecting/bouncing around?
I don't notice anything so perhaps this is negligible.
Anyway, just curious..
I still use some of my full-frame lenses on my K-S1, but it is a question of try it and see. Many of my m42 Takumars , including Takumar, Super-Takumar and SMC coated versions have been sold not because they were not sharp, or potentially useable, but simply exhibited too much chromatic aberration to be satisfactory without correction, something I do not do because I rarely resort to any processing . The CA was not in any particular focal length, but scattered across the whole spectrum of lengths. The same applied to many non-Pentax lenses as well, but interestingly zoom lenses seemed less affected than prime lenses, and not just because they were newer computations. So simple answer is try it and see!.
