stuck focus on 35/1.4 AI

<< < (2/4) > >>

Bruno Schroder:
Yes, this one

David H. Hartman:
I cleaned a 24/2.8 AI between the aperture blades because they must have been coated excessively and they shed so much photos were foggy looking. I don't remember it being difficult. I ascribed a thin line with a sharp needle for realignment. The complete read group was the CRC. The 35/1.4 might be a milk run. :)

Didn't realise that this lens has CRC, i thought the Ai-S was the only one that had it  :o :o :o

Roland Vink:
Nope, all the 35/1.4 versions have CRC (as do all 28/2 and 24/2.8 lenses).
When it was introduced in 1970 it was a very advanced lens, with a modern optical design, floating elements and fully multicoated.

You might be thinking of the 28/2.8, which gained CRC with the AIS version.
