lct Posted March 26 Share #21 Posted March 26 Advertisement (gone after registration) A reissue of the Elmar-M 50/2.8 would have a single hard stop, i guess, the same way as the Macro-Elmar 90/4 v2 compared to the v1 of it. I could be interested then but the current Elmar-M remains my favorite "slow" 50 since i bought my first copy with the M6J in the nineties. Great lens definitely 👍 1 Link to post Share on other sites More sharing options...

charlesphoto99 Posted March 26 Share #22 Posted March 26 (edited) IME it's best to keep these type of lenses extended, unless one absolutely needs the compactness when retracted. My 90mm f4 macro (v1) had to go to repair due to the inner barrel falling apart. Just give the inner barrel a quick wipe when retracting if it's been a while or it's dirty. Point being, if left extended, one also doesn't have to concern themselves with aligning the correct extension stop.

I never collapse the Elmar-M as I don't see the point (I would happily use a rigid version of this lens if Leica made one). Also, I discovered that repeated collapsing and extending stretches the springs that hold the lens in place when extended, requiring some adjustment to tighten them up and stop the lens barrel wobbling. Put together with the warning to always extend the lens before mounting or dismounting (especially on digital M), this gives me several reasons to keep it always extended.

Passivsportler76 Posted August 1 Share #25 Posted August 1 Really intersted in this lens. Just a short question for you all. Is it possible to collapse the lens while mounted on a modern digital M (M10) or only on film Ms? Link to post Share on other sites More sharing options...

The answer is yes, but you must not mount it in the collapsed state. 4 Link to post Share on other sites More sharing options...

Recently decided on a whim to add back a new 50 Summicron v.5 (sold my 35 Summilux FLE). Better than I remember from using one many years ago, and a terrific companion of late on my M10 Monochrom. Nice handling, smooth operation and fine IQ. No flaring issues that I’ve yet encountered. Also pleased with results pairing it with my M10-R, but that gets far less use. Still have my 50 Summilux ASPH v.1, but I’ve put it aside for now. Go figure; I guess one can go back.

250swb Posted August 2 Share #29 Posted August 2 If you aren't clumsy you can mount it in the collapsed position, it can't touch the sensor or shutter no matter how cack-handed you are. The warning is for the people who wouldn't feel there's a problem lining the lens up by touch alone, pushing against the focus arm or rattling it around and scratching the black paint off. Set the camera on 'B' and open the door then see how close the back of the lens gets to the shutter, nowhere near, then try mounting it at an odd clumsy angle, again nowhere near.

Forgive me, but I am one who moves the lens to minimum focus before mounting to avoid touching rangefinder cam, so I accept risk adverse!😉 2 Link to post Share on other sites More sharing options...

Like I said, the advice is for clumsy people, I don't see how it's 'too easy to hit the roller cam' unless somebody mounts all their lenses by fumbling about. Any less can potentially hit the roller cam and all lenses make contact with it even before they are fully mounted. Just centre the lens in the opening, it should be easy enough.

lct Posted August 2 Share #33 Posted August 2 Good for you but it still happens to me after 20+ years experience so mounting the lens in collapsed position is an advice i would not give in any way. YMMV. 1 Link to post Share on other sites More sharing options...

YMMV. Fact or fiction, or another Leica myth? I've gone through the Leica owners manuals that I have and neither the M3, M2, M4-P, or MP manuals mention needing to have a collapsible lens extended when mounting it. Then I thought I'd have a look at the M5 manual given that one should mention the 'issue', and it does, but not to retract collapsible lenses 'at all' (because of the meter arm). The M8 manual doesn't mention it as an issue but the M10 manual says retractable lenses should never be retracted. However the depth of the body from the face of the lens mount to shutter is 24mm, and the maximum depth of the 50mm Elmar M from lens flange to the rearmost part of the lens is 18mm, so there's 6mm to play with on the M10 and no other impediments in the way. I have the lens mount on my M10 right now and there was no crunching and grinding noise when I mounted it in the collapsed position. So as far as I can see Leica have never warned against mounting a lens retracted, they've only ever warned when never to collapse it at all. Which in the case of the M10 is crying wolf because it doesn't touch anything inside anyway, so there is only one camera the Elmar M cannot be collapsed on or mounted collapsed, the M5.

TomB_tx Posted August 2 Share #35 Posted August 2 55 minutes ago, 250swb said: So as far as I can see Leica have never warned against mounting a lens retracted Why would a lens be "retracted" when not mounted on a camera? I think Leitz expected lenses to be fitted with a rear cap to protect them when not on a camera, which means the lenses would be in the extended state when off the camera, and they didn't expect someone to then collapse the lens before mounting. 1 Link to post Share on other sites More sharing options...

Considering the precision in the construction of the rest of the camera that 2mm gap is massive. Every lens touches the roller even before it's been twisted to mount it.

wizard Posted August 2 Share #40 Posted August 2 (edited) vor 11 Minuten schrieb 250swb: that 2mm gap is massive. I don't think that gap is 2mm wide. According to my own observation, a retracted barrel does come very close to the roller indeed. And if the retracted lens barrel touches the roller on mounting the lens, the roller may be pushed inwards a lot further than by touching the roller cam on the lens, and damage to the roller mechanism or at least its adjustment may occur. I am with lct here, it is safer to mount such a lens in its extracted position, but there is no risk of retracting the lens barrel once the lens has been mounted on the camera body.
