gettons Posted September 21, 2020 Share #1 Posted September 21, 2020 (edited) Advertisement (gone after registration) Hello there, I have just received my M3 and whilst investigating it is functioning properly, I tried mounting an Elmar 28mm M-mount like the one attached (the idea is to use both a 50mm ridig and a 28mm elmar with an external optical viewfinder on the M3). Problem is the lens' red dot gets in the way with the lens release button whilst I twist the lens, and I am therefore unable to screw it to the body. I can screw with no problem at all using my M6. Are you aware of any difference between M3 and M6 when it comes to lens mount? I mean they are both M-mount but the lens release button in the M3 is slightly thicker than the one in the M6.

Advertisement Posted September 21, 2020 Posted September 21, 2020 Hi gettons, Take a look here M3 and modern Elmar 28mm. I'm sure you'll find what you were looking for!
Reini Posted September 21, 2020 Share #2 Posted September 21, 2020 You mean the 28mm Elmarit asph? The red button on the Elmarit touches the upper edge of the release button border, but it can be locked on the M3. Link to post Share on other sites More sharing options...
a.noctilux Posted September 21, 2020 Share #3 Posted September 21, 2020 (edited) Same problem, like here https://www.l-camera-forum.com/topic/127042-leica-28mm-f28-elmarit-m-asph-thoughts/?do=findComment&comment=2400581 When I want to mount the Elmarit-M 28 asph. on my M3, the red dot fell, touching the release button, so to use this lens on my M3, red dot must be deleted.

I have not done the modification, just had the red dot deleted.

Matlock Posted September 21, 2020 Share #4 Posted September 21, 2020 There are quite a few lenses (the 7Artisans 50mm being one) which cannot be fitted on the M3. Link to post Share on other sites More sharing options...

I have been trying to mount it but I am a little concerned as the red dot prevents me to push the lens fully in the mount. have you successfully mounted a 28mm elmarit on an m3?

Reini Posted September 21, 2020 Share #8 Posted September 21, 2020 (edited) Yes, it works and then clicks into place nicely. When attaching the lens, try to lift it up slightly and then rotate it. I don't want to work on mine now. Maybe you can remove the release button guard and file something above? Edited September 21, 2020 by Reini Link to post Share on other sites More sharing options...

I see. when you say it fell, do you mean it actually came off? If so, after it came off, can you put it back on the lens somehow or it’s gone?

a.noctilux Posted September 21, 2020 Share #10 Posted September 21, 2020 I glued the red dot back with not too strong glue later on, as I've done so many times on my lenses. Why didn't I use strong glue ? In the past, the red dot broke in pieces when hit somewhere, in use or transportation, when glued strong. 1 Link to post Share on other sites More sharing options...
gettons Posted September 21, 2020 Author Share #11 Posted September 21, 2020 Same thing here apparently Upon checking with a couple stores the red dot really does not make any difference when it comes to the value of the lens (unless for mint status and collection purposes). So I decided to take it off, but I am struggling as it's very well in place. Probably best to use a glue solvent? I Link to post Share on other sites More sharing options...

Probably best to use a x-acto knife or small screw driver. Or, maybe just try to mount it and let the camera push it off...

105012 Posted September 23, 2020 Share #13 Posted September 23, 2020 Later M3's have a reduced size lens release button guard (slightly smaller). On 1966 M3's there is no lens release button guard. I prefer the feel of the earlier M3 release button guard, but obviously a problem for cylindrically shaped lenses with button... As it happens none of my lenses have this issue (including APO-Telyt 135mm)... Link to post Share on other sites More sharing options...

We know that later M3s had the button guard reduced and then discontinued. The 7Artisan lens (at least the models I have) depress the actual release button and the lens cannot lock, later lenses may have been modified?

Rennrocky Posted September 23, 2020 Share #16 Posted September 23, 2020 I think that the lens is modified. But I don´t have experience with a early M3. With my two M2 and my M3 (No +1.000.000) I have no problems 1 Link to post Share on other sites More sharing options...
raizans Posted September 24, 2020 Share #17 Posted September 24, 2020 Some M3 have a lens release button and shroud with less clearance than others. https://rangefinderforum.com/forums/showpost.php?p=2965002&postcount=2102 from MaZo: Welcome, dear visitor!

Yes, I remember well that this question was discussed also in the Forum some years ago : both collar and button had variations during the life of M3... the problem of interferencing did arise with some lens introduced in those years (don't remember which one... maybe a 90 mm) Link to post Share on other sites More sharing options...
Reini Posted October 3, 2020 Share #19 Posted October 3, 2020 I have the same problem with my new M3. The Elmarit 28mm asph cannot be connected because of the red dot. Apart from that I won't mount it there. Link to post Share on other sites More sharing options...
