Hello everybody, this is my first post and I would like to extend a friendly hello to all of you and also to thank you for your time! This thread is not about finding the right screws for adjusting the rangefinder, but rather about one of them not wanting to move. The infinity adjustment (horizontal plane) seems to be a tiny bit out of alignment with my M5, and although it probably will not have a significant effect, it still nags me. One factor might be that the brass barrel of the lens I commonly use appears to be quite worn, so that when "freshly" attaching the lens, everything seems to be in order but never goes back to true inifity after the lens is focused to a closer distance and back to infinity, if this makes sense. Anyway, the screw inside the roller at the end of the rangefinder arm inside the lens mount does not move. I have tried several straight and angled screwdrivers, even filed one down for better fit, but still: it won't budge. I am afraid of stripping the head of the screw/damaging the arm and wonder: can or should the eccentric screw at the end of the rangefinder arm be lubricated in any way? Or will this result in unwanted movement/reoccuring maladjustment of the screw? When looking straight at the rangefinder arm from the front, there seems to be a small opening in the arm through which I can see the screw, which is why I'm wondering if it's meant to be used for lubrication purposes. What confuses me most though, is that my camera technician has adjusted the rangefinder several times already, and will most probably also have used this screw (although there seem to be other ways after taking the top plate off). Maybe I should ask him if he applied any kind of bonding agent to keep it in place. Although I'd wonder where he should have put it, since it inevitably would come into contact with the roller, inhibiting it from moving freely. If all of this is too confusing, I can add some pictures later for clarification. Thank all of you for your time and have a nice day!
I bought the APO Summicron 90mm new with my M9 last December. I could never get a sharp image with it and figured it was my inability to focus. I bought a 50 Noct, 28 Cron, 35 Cron and 50 Cron. Every lens is bightingly sharp and I can nail the focus of the Noct at f/1 just about every time. Thus my 90mm was left abandoned until May when I sent it back to Solms for adjustment. Two months later (yesterday) it arrived back. I took a few shots at f/2 at minimum focus distance and saw the crazy sharpness that everyone talks about. I then took some shots at medium to infinity distance at f/2 and could not get one that was even close to sharp. Even infinity seemed soft. The focus seems a bit stiff and sticky and that does not help, but I took much care focussing on each subject from in front and then beyond focus. This gives me a number of problems. I would never sell a lens in this state. All my other lenses are a picture of razor sharp delight on my M9 so I do not want Solms tinkering with my M9. Do I just keep sending the 90 by to Solms until they get it right. Would you do a series of bench tests to get a very complete understanding of the issues. Should I try the 90 on my MP and see if those results are sharp, or would that just open up more questions. Frankly I am so delighted with my 28/35/50 Crons I would not care if I never saw this troublesome lens again. Thank you so much, as ever, for your help. Ian
I suspect that the vertical alignment of my M8's rangefinder is just slightly off. E.g. I can read the text in a newspaper through the viewfinder, but it always seems less crisp in the focusing patch. Anyhow, I'm wondering how difficult it is to adjust the vertical alignment and get it dead on. I understand that one needs a special tool to use once she removes the red dot on the front of the camera. That's fine, as I can get one of the adjustment tools. However, what worries me is whether I'll be able to get the alignment right, as I'll just be using my eyes (with glasses) and no type of objective measurement. A question for people who have performed this adjustment themselves: How long did you have to adjust it? Do you feel like you got it dead-on perfectly aligned? Did you find it difficult? Thanks!
