Interesting thoughts Boris. But I never saw that effect with a 50mm on 'FF' or 30-35mm on APS-C. Viewfinder/lens may very well be the 'culprit'. Or lack of 31/43 Limited :) :) I really don't think this is a DOF issue. After all, my FA50/1.4 has less d...@f1.4 than the 80/2.8 on 6x6.
The problem is the following, my (very basic) enlarger is 24x36 only. No 6x6 prints at home. No way to check until I can afford a proper enlarger (which ideally would do up to 4"x5") which won't be tomorrow or the day after :( 2011/1/11 Boris Liberman <bori...@gmail.com>: > On 1/7/2011 3:54 PM, Thibouille wrote: >> >> ...with some lenses (Pentax of course). >> I know this has been debated quite much and that it is somewhat weird >> to talk about 3D in a photograph but... >> man, my C330 does throw at me exactly that in its waist level finder >> and 80mm/2.8 lens. >> >> Is that the lens?
