Here's my experience with the CL. I love them and they do not attract attention from potential thieves.Originally Posted by Toni H.
I have a Rokkor 40mm which is superb, but it has a tiny spot of fungus on an edge. Cannot be easily cleaned because the two front elements are spun together.
Meter cells in both mine started to die so I would have that checked before buying. Up to a few months ago meter cells were available.
Most collapsible lenses will foul the meter arm.
If I wanted a 40mm I would seriously consider the new Voigtlander 40 f1.5
