Test Images Mamiya ZD Back

I will not indulge in some scientific test series which steal my value time to take photographs, but I created some sample shots with all my current (5) lenses to get a bit an idea how the lens perform. Yes, you are right it should be a range of f-stops for all lenses to compare 2.8 vs. 32 and center vs outer part of the lens. Maybe later (i doubt so).
