I borrowed a Canon EF 70-200/4.0 IS USM for a wedding next week and compared it with my CZJ Sonnar 135/3.5 electric MC. I did some test shots and was quite happy to see that the vintage Sonnar is still a good performer compared to a modern lens. The only huge difference i could find is in backlight situations.
It's not the first time i see the Sonnar not performing well in such situations. I am wondering, is this normal for that lens or is it in bad shape? Is cleaning the front lens too often bad for the coating, like some people say? Does "MC" from CZJ have anything to do with T* from CZ? Is there anything i can do to increase the performance of the Sonnar?
Please click on the images to see the difference clearly.

MC and T* are both multi coating, that's all. |

Yes, unfortunately I agree with your observation
Most modern lenses seem to have better coatings
that can handle backlight.
I have compared my modern AF digital Canon lenses with
semi-old Pentacon 2.8/135mm, Tessar 2.8/50mm and Orestegon 2.8/28mm
and all of these were not good at all when backlit. |

Thanx for your replies. My copy seems to be OK. So i just have to make sure i don't get any stray light into the Sonnar.
What do you think about wiping off the coating of the front lens by cleaning it too many times? Is it possible or just a myth? _________________

I am not acquainted with modern lenses but one of the things one must realize and be willing to accept is that vintage/classic is not always up to modern technology. _________________ Body: Fujifilm X-E1

If the lens' front element still has an all over even purple or gold colour then the coating is likely OK.
Using the built-in hood might mitigate the veiling flare somewhat though - do you use it? |
