The focus mount of this version Sonnar is fragile. This one is good, probably not used much: the middle triplet was loose when I got it, did not hold focus. I have another one that saw heavy use, the helical was loose and the focus had a lot of slop in it. For that one; I made a sleeve for the mechanism to hold the inner helical steady as it was used.
