Swietokrzyski Bridge with National Stadion at Warsaw
Notes
Comparing this photo at f/22 with other taken with the same frame but lower aperture settings like f/4, f/5.6, f/11 - I am starting to believe that diffraction isn't always a main problem. This with f/22 is the best. I hope to compare the yield of Sonnar 2.8/200 MC with Sonnar 4/180 CF at the same frame.
Thanks Joe and Lilia, Your opinions are the ones of most valued by me. I will try to think about blue sky Lilia, I need just to make an query to Augurs.
Carol, I don't want to foretell but with my previous experiences I used to recognize f/5.6 result as best with double gaussian lenses such as Glatzel Planar 1.4/50mm or Pancolar 1.4/55mm. I will try it to recheck it at infinity (and post it). Higher aperture should boarden a DoF but the overall quality drop may overwhelm it. I wouldn't be supprised with similar positive effect of smallest apperture with classical sonnar design like ZM Sonnar 1.5/50mm and CF Sonnar 4/180mm.
