silver vs black ZM lenses

[Jerevan]

I have been thinking about getting a Planar 50/2 or a C-Biogon 35/2.8.

Do the the exterior of the silver lenses hold up better compared to the black ones?

Does anyone have a picture of how the black ZM lenses are looking when they are used a (good) bit?

I do not have a specific photo to post...but I have owned a 25, 35 and 50. Each was black and they seem very durable and the finish is very strong. Unless you have "finger tips" made of "sand paper" I have yet to see on that showed any finish wear. They are really high quality. So I would suggest a black Zeiss.
