Hi there! After years of contemplating I am super grateful to have found this beauty in such perfect condition. I have shot my first 10 films and I really love the output.
One thing keept bugging me though. When put to infinity (summicron 35) the rangefinder adjusted perfectly fine, in near distances however, it was off. 1 measured meter was sharp at around 0,9 on the lense. I had it in a camera store now and while it is perfectly fine in the near distances now, it is a tiny bit off in infinity. I need to turn it back like half a mm.
Should I just let it be and enjoy or do you have other recommendations for me?
Thanks in advance!
