twocutedogs Posted December 1, 2011 Share #1 Posted December 1, 2011 Advertisement (gone after registration) Anyone else noticed that the 35 cron will wobble a bit with the MP? I have tried over 10 crons (and even one 35 summarit) and they all wobble. It doesn't seem to be my MP as I tried a 35 cron with an MP in the Leica store and it was loose too. Leica tell me that it isn't an issue but wondered what others thought. Link to post Share on other sites More sharing options...
Advertisement Posted December 1, 2011 Posted December 1, 2011 Hi twocutedogs, Take a look here Leica MP and 35mm Summicron. I'm sure you'll find what you were looking for!
wattsy Posted December 1, 2011 Share #2 Posted December 1, 2011 Not sure what kind of wobble you are describing - do you mean rotational play at the lens mount? Link to post Share on other sites More sharing options...
Marty Posted December 1, 2011 Share #3 Posted December 1, 2011 I wouldn't call it a wobble but yes all my lenses are definitely tighter on my M9 than the MP including the 35 Summicron ASPH. Doubt it's a bad thing and certainly don't believe this has affected anything else... Link to post Share on other sites More sharing options...
peter_n Posted December 1, 2011 Share #4 Posted December 1, 2011 I've not had the experience. I use a v.1 and an ASPH on an MP3 and a regular MP. No wobbles on either camera body, they both mount properly and are secure once on the camera. Link to post Share on other sites More sharing options...
Keith (M) Posted December 1, 2011 Share #5 Posted December 1, 2011 The fit of a lens on my M9 is much tighter than on my M7 (from new). In my case the lenses went onto the M7 like a hot knife through butter and there is slight rotational play when locked in place whilst on the M9 a very firm grip was needed and there is no play. Never having had Leica's before I expressed concern about the M7 to the dealer (who then spoke with Milton Keynes) and the response went along the lines of "they are all like that, Sir". Hmmm, I was not totally convinced but accepted their word. Recently I bought an M4 and was surprised to find that the lens-fit was very similar indeed to the M9. As it happens, the elecronics on the M7 failed early last month so the camera is currently at Solms and I included the concerns about the 'loose' lens fit amongst the list of items needing attention. It will be interesting to see if there is any difference when it is returned to me. Link to post Share on other sites More sharing options...

lincoln_m Posted December 2, 2011 Share #7 Posted December 2, 2011 Advertisement (gone after registration) My lenses are a much tighter (too much?) fit on my 46 year old M2 than on my M7 or MP. I haven't noticed much difference between M7 and MP. I guess it only takes a few thou extra thickness of the M mount to make a big difference in the feel. Perhaps a thin shim can be added to the film Ms or taken out of the M9 to make the fit correct? Perhaps more people who notice this should call Leica so they realise there is a slight issue in some cases, I guess serial numbers of body and lens are what they need.

Jon Pop Posted December 3, 2011 Share #8 Posted December 3, 2011 I don't own a 35mm Summicron so I can't comment on that, however, I do own both an MP and an M9. My lenses are: 28mm Elmarit 2.8 Asph, 35mm Zeiss Biogon C, 50mm summicron, and 90mm Elmar C f4. I noticed a significantly different 'fit' of the lenses between the MP and the M9. I found that all my lenses mounted on my MP smoothly and consistently, with no play but not too tight. My MP has seen moderate use, but is far, far from being 'all broken in' like an M3 from the late 50s. However, the M9 mount doesn't feel as smooth, nor is it as consistent lens to lens. Particularly the 28 - it's a really tight fit, actually a bit difficult to mount. It's almost as though the fit of the M9 mount feels less 'polished', as though the metal was drier or something. Hard to describe. I wouldn't care, except that as I said, the 28 is actually a bit of a bear to mount. I was told by Leica that the mount on the M9 is different than the MP in that it's 'slightly thinner', but that's all I have to offer. Link to post Share on other sites More sharing options...
MPerson Posted December 3, 2011 Share #9 Posted December 3, 2011 Just dug out my Summicron 35/2 (latest version) - I never use it now - and it mounts smoothly and firmly with no play whatsoever on my MP, M2 and CL. Link to post Share on other sites More sharing options...

250swb Posted December 23, 2011 Share #11 Posted December 23, 2011 I never cease to be amazed at what people can find to worry about. You say you tried ten Summicron's and still need to ask if a little play is unusual? Steve Link to post Share on other sites More sharing options...

twocutedogs Posted December 24, 2011 Author Share #13 Posted December 24, 2011 thanks for the replies all. i think that the problem was with my MP. some of them are made with a looser mount - works well with all lenses except the 35 cron. i tried a 35 cron on another few MPs are about half were loose. cheers.

Jon Pop Posted December 24, 2011 Share #14 Posted December 24, 2011 I have an MP and an M9. While I don't have any problems with free play or wobbling with lenses mounted on the MP, I do know that the mounting on the M9 is extremely tight in some circumstances. I actually prefer it on the MP - just the right amount of resistance, but smooth all the way, solid, and consistent across every lens I have. With the M9, however, my 28 Elmarit Asph is extremely tight, as in it's quite difficult. I have been told that the mounts are 'different'. Someone on the forum said something like "it fits tight...why complain?" etc., and implied that I was over-thinking or over-worried about something so trivial. It's not that at all - it's more that I'd prefer not to struggle to mount a $2000 lens on a $7000 camera. Too loose isn't good...but neither is so tight that you struggle, and can't make quick changes. All I know is that my MP is perfect...but then it's perfect in a lot of other ways too!!

Never had a "wobble" in my MP's nor M9/8's Nice word " Wobble" sounds like Hugh Laury would say in " Blackadder" . Link to post Share on other sites More sharing options...
vonheim Posted January 2, 2012 Share #16 Posted January 2, 2012 Anyone else noticed that the 35 cron will wobble a bit with the MP? I have tried over 10 crons (and even one 35 summarit) and they all wobble. It doesn't seem to be my MP as I tried a 35 cron with an MP in the Leica store and it was loose too. Leica tell me that it isn't an issue but wondered what others thought. I have used a Leica MP for a couple of months now, and lenses are definitely "loose" when mounted on it. My 50 1.4 ASPH has actually fallen off twice. Once I caught it an inch from the camera, and the second time it was luckily sitting on my desk. Very strange indeed. I will send the camera in for service. The M9 has a much tighter fit and I detect no movement with any mounted lens (that I own). My first four rolls from the MP are still undeveloped, so I don't know if it will affect the pictures. My suspicions are that film is not flat enough for it to matter. When using the MP now I just make extra sure to check the fit in the mount frequently. Cheers, Knut Link to post Share on other sites More sharing options...
normclarke Posted January 2, 2012 Share #17 Posted January 2, 2012 The fit is a function of the retaining spring that sits behind the mount and due to production tolerances may vary, but not enough to cause a catastrophic problem. It would be a fairly simple fix to strip the camera and reset the spring to impart a firmer action to the lens mounting. I guess that batch sample variation has a part in this as as far as I can tell this part has not changed in the life of the M system. Best, normclarke.

jhild Posted January 7, 2012 Share #19 Posted January 7, 2012 The reason IS the retaining spring behind the bayonett. It´s hold in place by 4 screws from behind. When a lens is mounted to the camera the spring is pressed against the bayonett which increases it´s diameter a little bit. Lensmounting is tough if there isn´t enough space for the retaining spring to expand that little bit. The solution is easy, once the camera is out of the body shell loosen the 4 screws an get the spring out. Use a dremel or something similar to reduce the spring´s diameter very little, 1/10th mm is enough. It still has to slip under the screws again what it doesn´t do if the diameter is reduced too much. Fit everything back in place, the 4 screws might be a bit tricky but it´s possible without special tools. Before the camera is going into the body shell again fit a lens to the bayonett and check out whether it´s better now, it usually is. I´ve done this on several M2,3,4-P bodies that were due for a CLA anyway and it always worked. No need to go for a new spring. Jo Link to post Share on other sites More sharing options...
