It is not razor sharp but enough for portrait. There are 3 things - tripod not used, I am not perfect with focusing and resolution posibilities of the scanner. At least tripod and better focusing should give the sharper image.
@Greg Heath Hello Greg, I mean that most (all) RB67 lenses are sharp or perfect sharp but it is question about proper focusing, IMHO. I am still in practise mode (of focusing) to get maximum from my RB67 lenses. What I know is that I have to learn/practise/know each part of the camera system to be familiar with all of them. I have to know the weaknesses to eliminate them and the strengths for maximum utilisation. There is no ideal aparatus for all purposes ;-)
