Advertisement Posted November 25, 2021 Posted November 25, 2021 Hi iek1968, Take a look here Leica III backfocuses around 4 cm. I'm sure you'll find what you were looking for!
qqphot Posted December 5, 2021 Share #2 Posted December 5, 2021 I forget which direction but it will be quite apparent once you try - set the lens against the infinity stop aimed at a very distant (1km +) object and adjust the rf adjusting screw one direction or another in miniscule increments, barely even more than steady pressure, perhaps 1/32nd of a turn at a time and it will be clear which direction brings the split images together until they are perfectly in register. I haven't ventured into messing with the focus arm length adjustment because I worry I'd make things worse and the infinity adjustment seems to be sufficient for me every time focus accuracy drifts off.

Ok thanks, I did it, it was pretty easy, but only my trusty Wiha 1mm screwdriver fit thru the hole. But then it got hold tightly of the adjustment screw. Question: I thought the Screwmount Leicas dont have a focus arm length adjustment, just the Ms do, am I wrong? Greetings Quote Link to post Share on other sites More sharing options...
