I recently tested my Leica M2 using a Telesar 35mm F3.5 LTM lens and this was a typical image:
I then then tested my Canon P with the same lens and this was a typical image:
Note the vignetting from use on the P which was not at all evident on the M2. The vignetting happened regardless of f-stop, although it may be more pronounced at certain f-stops.
FYI the Telesar 35mm F3.5 is a compact Japanese-made LTM wide that appears identical to the more common Kyoei Acall 35mm F3.5.
I examined the interior of my P and it seems more tightly baffled than a Leica M2, but I did not actually measure it (I will). I know that the P cannot be used with a lot of collapsible lenses, whereas the M2 can, suggesting that Canon really necked down the baffles so much certain 3rd party lenses vignette. Does anyone have similar experiences with the P or similar Canon models?
