Advertisement Posted December 23, 2009 Posted December 23, 2009 Hi jsrockit, Take a look here Which collapsible lenses are safe to collapse with M8?. I'm sure you'll find what you were looking for!
barnack Posted December 23, 2009 Share #2 Posted December 23, 2009 I use the new version of the 50mm f/2.8 Elmar and have had no problems. This lens is a perfect compliment to the M8. It is small and takes extermely sharp photos. Link to post Share on other sites More sharing options...
jaapv Posted December 23, 2009 Share #3 Posted December 23, 2009 The 90 macro is fine too. Link to post Share on other sites More sharing options...
jsrockit Posted December 23, 2009 Author Share #4 Posted December 23, 2009 I should've added that I'm looking at the older collapsibles... I knew the newer ones work well. Thanks guys. Link to post Share on other sites More sharing options...
UliWer Posted December 23, 2009 Share #5 Posted December 23, 2009 Here (and in following postings) http://www.l-camera-forum.com/leica-forum/leica-m9-forum/102865-screwmount-elmar-50mm-m9.html#post1086292 we did a little research on the topic of collapsible lenses for the M8/M9: Keep in mind that the main risks come from hitting something when you mount the lens collapsed. So only mount it uncollapsed Link to post Share on other sites More sharing options...
sarav Posted December 23, 2009 Share #6 Posted December 23, 2009 I know what the M8 manual says and I've read all of the conflicting information online. I'd would like to know, from people who know from experience, which collapsible lenses you've been able to collapse without harming the M8. I normally use Elmar 50 1:2.8 from 1966 both in M8 and M9 without any trouble. remember to mount and unmount it extended because collapsed could hurt rangefinder-cam or black-tinted inner parts.

I'd would like to know, from people who know from experience, which collapsible lenses you've been able to collapse without harming the M8. From my experience: Ok any of the 50s (including Summar and Summicron), NOT the Elmar 90 collapsible. Sarav's advice is important,and I can add that has to be AVOIDED to accidentally fire the shutter with lens collapsed. Link to post Share on other sites More sharing options...
jsrockit Posted December 24, 2009 Author Share #8 Posted December 24, 2009 Ok, but once the camera is turned off and the lens is mounted, the f/2.8 50mm elmar, from any time period, can be collapsed? Anyone know if the f/3.5 Elmar can be collapsed properly? Link to post Share on other sites More sharing options...
sarav Posted December 24, 2009 Share #9 Posted December 24, 2009 Ok, but once the camera is turned off and the lens is mounted, the f/2.8 50mm elmar, from any time period, can be collapsed? Anyone know if the f/3.5 Elmar can be collapsed properly? Yes, the Elmar 50/2.8 can be collapsed. For older lenses, manufactured before 1961, you have to verify. Happy Christmas!

Stefan-S Posted December 24, 2009 Share #10 Posted December 24, 2009 I have also used Elmar 3.5/50 amd Hektor 2.5/50 from the 1930s,without problems,even collapsed.It works for me,you must try for yourselve,i'm not responsible for you. Link to post Share on other sites More sharing options...

Do you really think I'm going to hold you responsible? You are just a voice out in internet-land as far as I'm concerned.

cbretteville Posted December 25, 2009 Share #12 Posted December 25, 2009 My 1952 50mm Summitar collapses fine on my M8 as does my 195x 50 Elmar RS. Carl Link to post Share on other sites More sharing options...

marknorton Posted January 5, 2010 Share #16 Posted January 5, 2010 Can I point you to this thread I did earlier in the year which showed a late 50mm Elmar on an M8. With this lens, at least, it is safe to collapse the lens, there is no issue at all with the shutter and the only recommendation is to follow sarav's comment and only mount/dismount the lens when it is extended. The clearance is quite small and you risk scratching the internal surface of the lens throat. http://www.l-camera-forum.com/leica-forum/leica-m8-forum/95761-safe-collapse-50mm-elmar.html Link to post Share on other sites More sharing options...

UliWer Posted January 5, 2010 Share #18 Posted January 5, 2010 What is supposed to happen, Luigi?. I have done that several times inadvertently and I have observed no ill effects. I think, it is supposed that nothing will happen (besides getting a very unsharp picture). Though things don't always behave as we suppose them to do. If you look into the camera without a lens mounted, you'll notice the ridges/edges/shields on both sides of the shutter. Here shown by wlaidlaw in a screw-mount body, but the principle is the same: http://www.l-camera-forum.com/leica-forum/attachments/leica-m9-forum/168697d1256076838-screwmount-elmar-50mm-m9-iif.jpg The space between those ridges is 24+something mm; every collapsible lens tube's diameter is bigger than that - so the tube can only hit those ridges but never directly on the shutter. In the M8/M9 those ridges differ from the older Ms: they are thinner, less high and look less stabile (perhaps they have the same stability or even a better one, but I won't test this.) Theoretically it might be possible that a collapsed lens pressed the ridges downward thus touching or obstructing the shutter. From what I see and have measured, I'd rule out this possibility for any 50mm Leica lens (I don't know the old collapsible 90mm Elmar). There is always enough room for the lens tube not hitting the ridges of the M8 (and the M9 if it has the same construction, which I don't know). The higher ones of the M2, M4might be touched and scratched, but as far as I know it has never been reported on M39 or M-mount cameras that a collapsed lens pressed the edges onto the shutter... Though you never can be sure: the lens might have an irregular tube, different non-Leica-lens etc. Those very theoretical risks make it safer not to collapse the lens and not to cock the shutter when it is collapsed. In any case one should avoid to mount a collpased lens, for the room to the sides of the camera throat is much, much narrower than the distance to ridges. I think the whole discussion was caused by fear of theoretical liability: "Leica told me that it was o.k. to use collapsible lenses, now I have those scratches, I sue them..."

luigi bertolotti Posted January 6, 2010 Share #20 Posted January 6, 2010 What is supposed to happen, Luigi?. I have done that several times inadvertently and I have observed no ill effects. Not sure it does happen something bad... but seems to me that there is some mech component of the shutter that, just for a moment, "sprouts" in front of the blades, a bit inside the rectangular area... I had the idea that it could touch a retracted lens' tube... but I can be wrong. Link to post Share on other sites More sharing options...
