It is no secret that the 35 biogon has a resolution drop in the extreme corners, but really the affected area is so tiny I would consider it negligible. I seem to have an excellent copy of the biogon, and it has even been finetuned at oberkochen, but I have to say, like with all traditional designs, it is very important at what distance to focus in order to maximize sharpness across the frame.
I agree Edward. I was surprised at my sample above when I first saw it, but the edges are very good. Overall sharpness is wonderfully even as the graphs would show.
I think Ron\'s analysis is a good one. The 35 cron will give some mid frame dips in return for the corners.

If the 25 Biogon samples look good, I\'m sending my camera in for the conversion. Question for those of you who use AF lenses, especially the 55 FE, is there any deleterious effect in terms of AF performance? I\'m going to assume that IQ (hopefully) is not diminished as a result of the mod.
My AF tests the camera seemed normal (with LAEA4). I asked about this, and they seemed to believe it would not hurt AF. The FE 35 and 55 will loose a tad of performance, but the Loxia 35/2 should be better. Pure speculation on my part.
Respectfully, that\'s a Meatball pitch. given the close distance. The shot you previously posted at infinity tells the tale of how the lens performs on the M9 at distance into the corners (unless there is something specifically going on with your copy or rangefinder).
