It's a relatively simple thing to accomplish, and remains in my contact book as a reference. Quite useful. [cut} Dear Paul, Since you have taken the pains to test several lenses to determine the optimum aperture, I hope you will share your findings. I always use f4 or f5.6 with my 35 mm and 50 mm Sumicrons, and have always heard and read that max resolution generally occurs at around f4-f5.6. Does this accord with your tests? Thanks, Joe Stephenson
