Having used 35mm for most of my photography I never had any problem with DOF and judging acceptable focus area as all manual focus lenses had scales marked. Then moving to digital 3-4 years ago and now trying 4/3s I find this a problem as there aren't any marks on lenses. I still use my Nikon MF lenses at times and now want to do some street photography with them, so will the scales still apply accurately as they did with FF or will I have factor in some difference. I did a little exercise comparing my 24mm manual focus lens (giving me effectively 48mm on 4/3s) and standard 4/3s kit lens set at 24mm and focusing on the same spot. The area in focus appeared the same in each case. So can I accept this as proof.
