Elmarit 90mm Focus Adjustment

[k__43]

I recently had my Elmarit 90mm f/2.8 repaired .. the early version silver with vulcanite

It was stiff in focus and also a bit stiff at the aperture - the repair solved that very good.
I have another problem now: I'm shure it doesn't focus properly anymore. When I focus to something at approx. 4 meter the scale says almost 5 and the focus is at ca. 5 meter (so I think thats what they call back focusing). It's ca. 10 cm off at 1m and doesn't get to infinity at all (the rangefinder, the scale goes to inf. alright).

Between my test now and the last time I used it I also had a CLA on my M2, so it might also be the M2. Although my Sonnar 50mm f/1.5 ZM focuses just fine (I think). The lens used to be fantastic back then.

How difficult is it to adjust the rf-coupling of the elmarit? does anyone has a manual of some sort for this?

thanks,
Kay

Whoever did the repair should fix it or give you a refund. It's obvious that they messed something up during reassembly.

yupp .. I thought of that too.
The reason for my asking is, that it quite possibly could be very easy (maybe not) and I could adjust it exactly for my M2.
Also I'm not sure I trust them to make it right the next time they try.
