Infinity and all are adjusted with the arm and roller. yes and no. if you correct the focus the infinity will shift and vice versa. technically it has nothing to do with focus accuracy but it affects each-other.

Advertisement Posted February 7, 2020 Posted February 7, 2020 Hi jaeger, Take a look here Southern California options for RF/focus adjustment?. I'm sure you'll find what you were looking for!
_Michael Posted February 7, 2020 Author Share #22 Posted February 7, 2020 As soon as I have some time, I will give this under-the-dot adjustment a try. Worst case, I accomplish nothing and sent it for service. As a side note, I did test with the 50mm cron this morning. It too is back focusing now so I have concluded the problem to be the body. No idea how it could have happened. It's been carefully stored and not banged or dropped since my last outing where results were great as usual.

Hi again, jaeger and _Michael I am not a technician, but I fail to understand how adjusting the vertical alignment has any effect whatsoever on infinity or focusing. A misaligned vertical rangefinder patch would be annoying but would not affect the horizontal movement of the patch image. I have never seen a vertical misalignment and I have been using Leicas since 1967. To _Michael: before going about removing the logo and playing with that adjustment, I suggest that you first try to adjust the roller; that may well be the only adjustment that you need doing and it is an easy one, all you need is a 2mm hex key. Hopefully you would not have to adjust the arm itself, that part has a spot of paint or such to keep it where it is, so at that point I might prefer to send the camera to Leica. From your original post, I think that a very small tweak of the roller will be all you need to do. 2 Link to post Share on other sites More sharing options...

I hadn't been shooting much, but yesterday I was able to get off a few frames. Much of that was wider view, landscapes/seascapes. I noticed that I could not get a sharp viewfinder focus at infinity. Mid distances I could get it properly set but looking at the images they just don't have the sharpness and clarity I have had up until now. This is using a Summicron 35mm ASPH v1. I have not dropped the camera, banged it or anything that I would expect to cause a problem. Once thing I consistently hear from Leica service is the very long time it takes to get anything done. Does anyone have any solid recommendations in Southern California to get this check and adjusted correctly, and do so in a reasonable amount of time? Thanks in advance My front focusing m240 no longer needs a lengthy trip to Leica, entirely because I followed the instructions contained in the previously linked thread. In my case, NOTHING other than the roller required adjustment. There was no vertical misalignment so it was not necessary to remove the red dot. Regarding anyone who might experience some trepidation in trying this procedure, let me add my experience that it's dead simple. Seriously. I agonized over the the procedure for about a week, reading and re reading the instruction thread. It took about 10 minutes as I only needed adjust the roller, and everything is now focusing correctly. My only surprise was having to adjust more than I had expected and the hex screw turned much easier than I would have anticipated. Perhaps that's the reason it was out of adjustment to begin with. My best WAG is that I bumped the roller arm doing a sloppy lens change and moved the roller adjustment. Regarding sending the camera to DAG, I corresponded with him about a week ago. He told me he had shortened his work week from 14 hours a day 7 days a week to 12 hours a day 6 1/2 day a week and had way more work than he was able to get around. I'm thinking that a trip to DAG, although excellent work would be pretty much guaranteed, might be time consuming.

arichter Posted February 14, 2020 Share #25 Posted February 14, 2020 Just before this thread started I sent my Leica M262 to Leica NJ for tune up and sensor cleaning. They confirmed the camera received 2/3, the next day they sent me an estimate which included "adjust range finder". Today, 2/14 they are shipping the camera back to me. Just my experience. To _Michael: While we are having this discussion you could have your camera already professionally serviced. Of course there is nothing wrong with trying to learn how to DIY something if you like. 1 Link to post Share on other sites More sharing options...

Thanx for posting this. I didn't send mine because they were not nearly as accommodating in their time frame when I inquired directly, citing a 6 week turnaround. If you don't mind saying, what was the cost of the service ? Welcome, dear visitor!

_Michael Posted February 15, 2020 Author Share #28 Posted February 15, 2020 Update: I spent 45-minutes making small adjustments to the roller using a 2mm hex. With multiple adjustments and multiple attempts to resolve, I still cannot get this correct. I am of the opinion that there is some vertical offset as well. I will send to Leica to complete the job and do a full clean and check. I will add that the roller adjustment was indeed very easy. I have a 2mm hex wrench with a long shaft that made it simple. I may still try to do some adjustments before sending it in, but arichter mentioned above, this could have possibly been resolved by now. I won't spend much more time trying to dial it in. I can get it to go from back focus to front focus, but can't get it right. Link to post Share on other sites More sharing options...
jaeger Posted February 16, 2020 Share #29 Posted February 16, 2020 (edited) the infinity setting is behind the logo. the hex on the roller is for back or front focus adjustments. Edited February 16, 2020 by jaeger Link to post Share on other sites More sharing options...

This contradicts what I’ve seen elsewhere, and as someone who’s successfully adjusted multiple M bodies, doesn’t fit with my experience. The adjustment behind the dot is the vertical. The hex key on the roller adjusts the whole system back and forwards, often referred to as the infinity adjustment. The slope of the rangefinder is adjusted by the screw at the base of the RF arm. A mis adjustment here may cause things like back-focus close-up and front-focus at large distances. The roller adjustment is the easiest to do (really easy with live-view) and luckily, most likely to be off. 1 Link to post Share on other sites More sharing options...
