The image pases into the anti-aliasing filter at an angle causing a cascade of light within the depth of the filter. This introduces more off-axis radial scatter than the symmetrical scatter of the perpendicular image forming rays in the center of the image. I have M and R lenses, a Liecaflex SL-Mot and M-3 + 35mm Summilux W Frogeyes. I always liked the larger mag of the M-3 finder over the M-2,M-4 etc.. I use the R lenses w/adapter on my Canon 5D with no visible image defects in 17x26" prints. (Canon IPF5000 printer) Egor,

If you try something with a longer flange distance it might be better. I found that FD lenses and OM lenses work nicely on the G1 ... better than the native lenses if you ask me. I've put up a lot on my blog about this (listed above) Hi
