Shivaswrath Posted August 11, 2019 Share #1  Posted August 11, 2019 Advertisement (gone after registration)  You guys have been very helpful so wanted to check here before I return my M10 or send it for repair... My 35/2 Cron has been working awesome on my new M10 until this weekend it stopped smoothly going into focus and started to skip when I was aligning things in the parallax box. Then it stopped skipping and it doesn't matter how much I turn the focus on the lens, the parallax box in my VF is frozen and I can't focus anymore. Few questions: 1. Is there a button I'm not pressing or have to reset on the M10 to get it back to normal? (I read the manual and there's nothing) 2. Could it be a brand new lens (I doubt this)? 3. Is it a parallax dud and needs to be returned to BH (camera is not even 10 days old so easier to return then repair).? Link to post Share on other sites More sharing options...

dau Posted August 11, 2019 Share #2 Â Posted August 11, 2019 The most usual cause for this kind of komplaint is an obstruction of the small window in front of the camera. Fingers are the most frequent culprits, but camera straps are also mentioned from time to time. In short, check to see if something is in front of the camera when the RF fails to work.

farnz Posted August 11, 2019 Share #3  Posted August 11, 2019 Might be an obstruction like a finger but that normally causes the rangefinder patch to disappear altogether until the the finger moves. It's probably more likely to be your hellicoid follower is stuck or is not connecting with the lens's hellicoid.  Take the lens off your M10 and you'll see a small round piece of metal on a sprung arm at the top of the opening where you put the lens.  When it's working properly the hellicoid (the threaded brass piece in the teardrop on the top of the lens mount) moves the round metal piece (the follower) into the camera and alters the what shows in the rangefinder patch.  You should be able to push the follower gently into the camera and it should return of its own accord.  If you look through the viewfinder while pushing teh follower then you should see something happening in the rangefinder patch.  If not, then it's off to the camera hospital. If that's working okay then it might be that the follower is not making contact with the follower because it's out of adjustment.  If you place the lens as though you were going to attach it to the camera you should be able to see whether the follower is likely to make contact with the hellicoid.  If it looks like it's not going to then it will need adjustment and it's time to visit the camera hospital.

a.noctilux Posted August 11, 2019 Share #5 Â Posted August 11, 2019 (edited) Same thing happened to me many times. If you want to, just push/pull the roller (gently) a couple of times. In my past experiences, it worked so many times when they were stuck by a lens or whatever. Â At that time, when it was very cold, grease froze up after taking the M out from hotter place . Or when it was very hot with some humidified dirt ... Edited August 11, 2019 by a.noctilux 1 Link to post Share on other sites More sharing options...

I tried moving it gently and now it won't move at all. Then I can pull it forward so it'll make contact with the lens and then it starts skipping and sticking again. I don't know if it's an easy fix or if it's a grease issue? The grease spot is visible so it seems like the screw is greased well. Link to post Share on other sites More sharing options...
a.noctilux Posted August 11, 2019 Share #7 Â Posted August 11, 2019 Advertisement (gone after registration) No luck. Not same thing as on my Ms. So after your description, maybe a spring had broken or lost. Â I think you can send to Leica. I hope that it would not take the too long to repair. 1 Link to post Share on other sites More sharing options...
Jeff S Posted August 12, 2019 Share #8  Posted August 12, 2019 (edited) If not returned, I would send it to DAG. A call in advance to confirm fix and to assure his availability and quick turnaround is wise. Jeff Edited August 12, 2019 by Jeff S Link to post Share on other sites More sharing options...

Shivaswrath Posted August 12, 2019 Author Share #12  Posted August 12, 2019 You guys are really awesome thanks for that extra direction! BH said they have them in stock so they'll swap but further or any issues (servicing), I'll use DAG then! Link to post Share on other sites More sharing options...
spydrxx Posted August 12, 2019 Share #13 Â Posted August 12, 2019 It is worth a peek at the list of camera repairers in the historica section. Besides DAG, I've also had very good results with Sherry Krauter and Youxin Ye, as have a number of other Leica owners. IMHO these are the top 3 in the USA - but there are also some excellent others...unfortunately often their turnaround times may be months rather than days or weeks.

Jean-Michel Posted August 12, 2019 Share #16  Posted August 12, 2019 If it is a new camera, and even if second hand, this sounds like a warranty job. Take it back to your dealer or contact Leica directly. Link to post Share on other sites More sharing options...

I mean it's the primary connection between your eyes and the lens-if I'm out of a camera every so often because of this it'll be problematic. Link to post Share on other sites More sharing options...
spydrxx Posted August 13, 2019 Share #18 Â Posted August 13, 2019 Only had a that type problem once in 50 years, and that was because I dropped the damned body with a lens on it. 2 Link to post Share on other sites More sharing options...

Always put the lens in close focus when mounting it and line up the red dots before putting the lens near the body.

It's not something that's happened to me in many many years of owning Leica cameras so it's not at all common and it's important to remember that Leica's with the same hellicoid and follower system have been used reliably in the harshest conditions by war correspondents for many years.
