|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.
