torbotek Posted October 13, 2012 Share #1 Posted October 13, 2012 Advertisement (gone after registration) Am i missing anything here? I bought a soft release for my M9 and it won't fit and I get resistance when I try to install it. I have an M7 and M3 with soft releases too and even if I try to switch soft releases, it still wont securely attach to my M9. What gives? Link to post Share on other sites More sharing options...

Jay B Posted October 13, 2012 Share #2 Posted October 13, 2012 I am having difficulties with my Monochrom & a new soft release as well. Did Leica change the threads on the digital bodies? Link to post Share on other sites More sharing options...
tobey bilek Posted October 13, 2012 Share #3 Posted October 13, 2012 I took the soft releases from the film cameras and put it on the M9 and M8. There is a problem with your camera or a tolerance stack up issue with a third party manufacturer. Link to post Share on other sites More sharing options...
torbotek Posted October 13, 2012 Author Share #4 Posted October 13, 2012 tobey- I think I am with JB. I got the last of the new Leica M9's. I have 2 other film Leica M's and the softies are working without problem. I think they changed the thread. In any case, i hope the manufacturers make new ones for the Monochrom and the New M's. I would like to hear more from other M users of newer models if they are experiencing my problem and JB. Thanks. Link to post Share on other sites More sharing options...
el.nino Posted October 13, 2012 Share #5 Posted October 13, 2012 I think they changed the thread. They definitely (!!) did not change the thread. Doing that would mean that none of the billions of cable releases around would fit. The thread has always been the same on every camera (from every manufacturer) for the last 70 years. I'm 100% sure that it's a tolerance issue with your M9. Link to post Share on other sites More sharing options...
jbl Posted October 13, 2012 Share #6 Posted October 13, 2012 I have a near-the-end M9P and the soft release fits fine. I use the Match Technical bug release fwiw. -jbl Link to post Share on other sites More sharing options...
Notman Posted October 13, 2012 Share #7 Posted October 13, 2012 Advertisement (gone after registration) I found the same problem when trying to fit a soft release button on my Monochrom. This is a machining error as the depth of the thread is too shallow leaving the thread too small at the entry point. 1 Link to post Share on other sites More sharing options...

pico Posted October 13, 2012 Share #10 Posted October 13, 2012 Well, it certainly seems to mess up any use of a cable release. DOY if you can. If it were deep enough already, I would tap it myself, otherwise drill then tap. I am pretty sure this is correct (by ISO 6053:1979) Tap: M3 x 0.5 Drill: 2.50 Link to post Share on other sites More sharing options...
el.nino Posted October 13, 2012 Share #11 Posted October 13, 2012 (edited) My thoughts exactly! I think they changed something here.... But not on purpose. Call Leica and have them replace your shutter release button. Neither any cable release manufacturer nor any soft button manufacturer will change anything!

Notman Posted October 13, 2012 Share #12 Posted October 13, 2012 I have measured my M 9 and Monochrom button heights and have calculated that the thread depth in the Monochrom button is 1.854 MM shallow. Link to post Share on other sites More sharing options...
Jay B Posted October 14, 2012 Share #13 Posted October 14, 2012 Yes, both my Match Tech soft release and my cable release only thread in a very small amount. Not far enough to stay in. Tested both with a M6 body today & the thread in properly. Time to take the MM to the dealer & show them. Link to post Share on other sites More sharing options...
LeicaMSeattle Posted October 14, 2012 Share #14 Posted October 14, 2012 I had a Match Technical soft shutter release on my M9-P as well and lost it because of this thread issue. The one on my M8-P has remained on only because I placed a minute amount of small fastener loctite on the threads before threading it on. I seldom if ever use a shutter release cable.

Notman Posted October 14, 2012 Share #15 Posted October 14, 2012 I have examined the internal threads on my Monochrom, M 9 M 8 and M7 cameras and they look to me as if they are tapered. The Monochrom is visably smaller at the entry point. The soft release buttons that I use have tapered external threads as do my cable releases 1 Can the material be tapped by hand safely? 2 Can a taper tap be obtainedto fix this problem? Good luck everyone. Link to post Share on other sites More sharing options...

It might help read the thread before writing. Yes, with even modest skills you can drill and tap to fix it.

Notman Posted October 14, 2012 Share #17 Posted October 14, 2012 I did read your simple solution but the thread in the stem is taper not straight.Measuring the male thread on a soft release button it is 3.43 mm on the large diameter, 1.65 mm on the small diameter over a thread length of 3.43mm. The spindle rod moves up and down and has a small amount of side movement which would present a small problem to an amateur to tap. Solution, a small amount of thread loctite on the thread or remove the spindle and place in the chuck of a C N C lathe. Program the computer to redrill the thread hole using a taper drill then programming to retap the hole using a taper tap. If these parts were made as a production run on a C N C lathe there should have been no quality problems. Making the parts on an ordinary lathe with no quality control then this type of problem can appear. 1 Link to post Share on other sites More sharing options...
torbotek Posted October 15, 2012 Author Share #18 Posted October 15, 2012 So my options are to bring it to a Leica dealer or to tinker it myself? Bringing it to a Leica dealer woudl be my only option as I am not very mechanically inclined to fix the soft release myself. Bringing it to a leica dealer will keep me away from my camera for a good while though... Link to post Share on other sites More sharing options...
Notman Posted October 15, 2012 Share #19 Posted October 15, 2012 I would consult your Leica dealer for advice. Your M 9 is too valuable to attempt to fix without professional help. Link to post Share on other sites More sharing options...
Jay B Posted October 15, 2012 Share #20 Posted October 15, 2012 According to my Leica rep, the shutter button thread was changed slightly with the advent of the M7, due to a number of reported issues of the release plunger pin going too deep and damaging the new style shutter button mechanism. The current Leica cable release (of course) fits & functions perfectly. Don't know what I'm going to do about my ill-fitting soft release. Link to post Share on other sites More sharing options...
