Sandokan Posted September 21, 2015 Share #1 Posted September 21, 2015 Advertisement (gone after registration) I had my rangefinder adjusted in December. Shots from a few weeks ago show that it was off again. Checking with the EVF confirms that is the case. My question: is that normal for the rangefinder to drift in 9 months? What could be causing it? I havent dinged the camera or badly treated it and it is not regularly in my day bag. Link to post Share on other sites More sharing options...
Advertisement Posted September 21, 2015 Posted September 21, 2015 Hi Sandokan, Take a look here Rangefinder adjustment. I'm sure you'll find what you were looking for!
jaapv Posted September 21, 2015 Share #2 Posted September 21, 2015 On an M240 it is not normal. My camera goes everywhere and has been spot-on over the last three years. The M9 and before could be knocked out of alignment much easier. Check for dirt on the roller wheel. Link to post Share on other sites More sharing options...
robert blu Posted September 21, 2015 Share #3 Posted September 21, 2015 I don't know about the M but it seems normal on my M7 when I use it regularly, see below link. This is why before buying a type 240 I ask Leica informations about the RF adjustment, if I have to ship the camera to Leica in Germany and how much time this would require (we know it is an operation which should not take too much time for an experienced technician) or id it could be made by a technician without invalidating the warranty. Unfortunately I was redirect to Leica Italy (it's where I live) but I din't get any answer. robert http://www.l-camera-forum.com/topic/247552-m-and-infinity-focus/ http://www.l-camera-forum.com/topic/249905-rf-calibration/ Link to post Share on other sites More sharing options...
edwardkaraa Posted September 21, 2015 Share #4 Posted September 21, 2015 This sounds strange to me. I have never had this issue with M6, M9 and M240, even though I always carry my camera wherever I go. I think the focus drift comes from the multitude of small knocks not from a major accident, so it is a good idea to use a leather half case and just be a bit gentle. By the way, could it be the lens?

Cliff S Posted September 21, 2015 Share #5 Posted September 21, 2015 Could also be rough lens insertion. Link to post Share on other sites More sharing options...
jaapv Posted September 21, 2015 Share #6 Posted September 21, 2015 On the M9 and before, vibrations, for instance from lying on the floor of an older light aircraft can rattle the rangefinder out of adjustment. Also if it falls on its baseplate with some force the vertical alignment can be knocked askew. In the 240 Leica addressed these issues resulting in a more robust mechanism. But it remains a precision instrument with all that that implies. Link to post Share on other sites More sharing options...
robert blu Posted September 21, 2015 Share #7 Posted September 21, 2015 Advertisement (gone after registration) Thanks edwardkaraa, CliffS and jaapv for these replays, nice to know the 240 has a more robust mechanism than the M9, and hopefully my M7 just to complete the information Leica Germany forwarded again to Leica Italia my request (and complain for no answer) and this time I received an answer, stating that the RF calibration of the M (240 type) has to be done in Leica Germany because needs an extreme precision in relation to the sensor position which can obtained only by a special machinery, which they have in Germany. In my opinion it makes sense. Unfortunately no mention about time required. robert Ms prices are becoming interesting to try the experience...one year old with still one year ...hope the new rumored camera will make the Ms used market even more interesting Link to post Share on other sites More sharing options...
jaapv Posted September 21, 2015 Share #8 Posted September 21, 2015 That is basically true, the most precise alignment for all focal lengths will come from a properly adjusted sensor ( within 1/100th of a mm I believe) The adjusting of the rangefinder mechanism can be done much more easily.
