Wide-open performance before CLA:

Compare with its sort of rival - Steinheil Munchen Tele Quinar 200/4 M42 after CLA:

An interesting comparison indeed!

Now, I have a question, that could sound stupid: I have a CZJ Sonnar 180/2,8 of this same type: how do you operate, to change the diaphragm pre-set?

Thank you in advance,

Enzo (E.L.)

thank you for your reply and I apologize for my late one.

Actually, my CZJena 180/2,8 has these same chrome "buttons": from the round window, it appears the "22" value, but I cannot understand how to operate on the mentioned buttons to change the set value. Besides that, my lens works perfectly, and gives excellent results (even enhanced if I don't forget to mount a sun-shade).

All the best,
