Pushing achromatic glass to the limit: Yashica 300/5.6 ML C/Y plus Mutar II (apo-grade 2x) on A7ii. Not the Yashica, but the Mutar is CZ. Pictured is one of our three local peregrine falcon fledglings from this morning. As of this evening, she has made a successful flight off the ledge, and is probably fully mobile.
To better suppress LCA, aperture was stopped down to f/11 which gave an effective f/22. Even with a tripod, the indirect light forced me to use dire settings of ISO 3200, 1/125sec. IBIS was completely worthless. While cropping is minimal and resizing for the web is helpful, I find the image quality a bit lacking. The same images with the Apo-Telyt-R 280 and heavier cropping were higher grade.
Yes Philip, this is truly a nice lens, and I am very happy I took a chance on it. I have wondered about the 35-70/3.4 for a long time now, but I think that I prefer primes in that range. Too bad that there isn't an old Contax 16-35 zoom. That, the 80-200/4 and a good 50 could do a lot for me as a mini-kit.

I think I need to get that lens after years of doubts. Nice samples with lovely colors - thanks for posting. What is your opinion about far corners?
Thank you Wilhelm.25/2.8 C/Y Distagon's farthest corners could a bit smeary on FF/APS-C mirrorless,at f8-11 and close/mid range distances.It doesn't however spoil the image in most cases.Just bear in mind that filed curvature is quite pronounced.
Look around for MM version of the 25/2.8 C/Y preferably.Among AE,the higher serial numer,the better.SNs below 61xxx rather not recommended.
