Zeiss S-Planar 135mm f5.6 C with t* coating?

Recommended Posts

I've recently acquired a black S-Planar C lens. Looking at the lens

elements I can see it has been multi coated, but I can't find the t*

mark on the barrow. Will there be a differenc in performanc between

this lens and a t* coated lens when dealing with strong backlighting?

the serial no. is 4534173. Any help would be greatly apriciated! I

just got my first roll back and I must say I'm very impressed with the

sharpness... with a loup i can count the capillaries in the model's

eyes!!!

This is a macro lens that requires either the Hasselblad auto bellow or a variable extenison tube for focussing. How are you focusing it? On what camera are you using it (I assume it is a Hasselbald, or something else via an adapter). If it's a black Zeiss lenses for Hassy then it is unlikely that it is not a T* couted lens. When you look at the surface of the lens what color does the coating appear to be?

Charlie,<br><br>As a general rule: if it is a black C lens, it probably indeed have T* multicoating.<br>However, as general rules go, there are exceptions, and the 135 mm lenses is one. They were all black.<br>Your lens is from about 1968 (a rather early one) an will have single layer T (no star) coating.<br><br>The difference in performance between T and T* coated lenses is minimal. Don't worry.

thank you Jean for your quick reply. I guess I got the lens at a bargin, as the dealer told me that it's not a t* lens. Lotus, I'm fully aware that this lens only works on a bellow, or a special focusing helical, both of wich I have. Thank you for pointing it out to me. FYI, some black C lenses do not have the T* coating... for example the black C 250mm 5.6 And Q.G. de Bakker... You Da Man!!! So i guess there was a stage when Zeiss did multi coating, but not T* multi coating?
