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.
Thank you. I am very touched and honored by your sentiments.
Be well,
Lilia
