Infantasy Posted July 25, 2016 Share #1 Posted July 25, 2016 Advertisement (gone after registration) I have a 90/2 lenses in R mount for using on my R5 SLR. Just bought a M9 and wonder if using a R to M mount adapter for using in M9. Cos I seldom to use the R5, does it worth to buy a adapter or simply sell the R90/2 and buy a used M lenses afterwards? Thanks Quote Link to post Share on other sites More sharing options...
Advertisement Posted July 25, 2016 Posted July 25, 2016 Hi Infantasy, Take a look here R to M adapter. I'm sure you'll find what you were looking for!
FrozenInTime Posted July 25, 2016 Share #2 Posted July 25, 2016 (edited) R to M only really practical at infinity as there is no rangefinder coupling. On the M.240 etc. live-view and the LCD and EVF would make it slightly more viable. Edited July 25, 2016 by FrozenInTime Quote Link to post Share on other sites More sharing options...
Infantasy Posted July 25, 2016 Author Share #3 Posted July 25, 2016 Do you mean it is unable to focus internally when using R lenses? Quote Link to post Share on other sites More sharing options...
steppenw0lf Posted July 25, 2016 Share #4 Posted July 25, 2016 When using R lenses on a M camera you need an electronic viewfinder or the LCD at the back for focusing. This is not possible with the M9. You probably need to upgrade to a M240 or M246, or a SL If you have a lot of practice and are good at estimating distances, you can also try to set the distance on the distance scale of the lens. This can be ok for wide-angles. But it will probably not work for a 90mm lens with its small depth of field. If you do not want to upgrade the camera, then you should sell the R lens and buy an equivalent M lens instead. Quote Link to post Share on other sites More sharing options...

lct Posted July 25, 2016 Share #6 Posted July 25, 2016 (edited) Better choose an M Lens for the M9. I like much my R 90/2 pre-apo but i find it useless w/o EVF or SLR cameras like my old Canon 5D. Edited July 25, 2016 by lct Quote Link to post Share on other sites More sharing options...
FrozenInTime Posted July 25, 2016 Share #7 Posted July 25, 2016 Advertisement (gone after registration) If you look into the lens mount of the M9 with the lens removed, you will see at the top a roller. The roller is pushed in and out by a cam on the rear of a rangefinder specific lens as focus ring is turned. This is a precision calibrated mechanical action which moves a mirror in the cameras rangefinder mechanism. SLR lenses don't have this cam so there is nothing to move M9 rangefinder mechanism.

Infantasy Posted July 27, 2016 Author Share #9 Posted July 27, 2016 BTW, I had seen some guys mounting old lenses onto Leica M series camera but not sure what lenses and what adapter/mount. Is it possible using non M-mount lenses on M9 but still able to focus correctly? Quote Link to post Share on other sites More sharing options...
steppenw0lf Posted July 27, 2016 Share #10 Posted July 27, 2016 The M9 can only focus with the rangefinder, so you need a rangefinder-coupled lens. That means a Leica M lens, a Leica screw-mount lens, a Zeiss ZM lens or a Voigtländer lens. All adapted lenses can only be focused via EVF or LCD, so only with M240, M246, SL. (Also not with M262, because it has no life-view). Quote Link to post Share on other sites More sharing options...
spydrxx Posted July 27, 2016 Share #11 Posted July 27, 2016 The old lenses you probably heard about are probably screw mount lenses, for an earlier version of the Leica bodies. Yes, they mount and focus just fine (& to infinity) with the proper mount. I use Leica, Canon & Tanack ones just fine on my screw mount & M bodies. Where caution should prevail is with some of the FSU (former Soviet Union) lenses, typically manufactured after appropriations settlements after WWII...many can be adjusted by a qualified technician to work perfectly well, but there were some very minor differences in manufacture which may make some unsuitable without some work being done on them.

Belle123 Posted August 8, 2016 Share #13 Posted August 8, 2016 Have a new question on this topic. Was doing a lens comparison between my Summicron M 35mm v4 and an ancient Summicron R 35mm with R to M adapter on my M246. I noticed isn't a 1:1 image comparison as the R image was magnified. So, does the r to m also have some extender qualities? Anyone have any data on this? Quote Link to post Share on other sites More sharing options...
Michael Geschlecht Posted August 8, 2016 Share #14 Posted August 8, 2016 Hello Billinghambaglady, How "magnified'? Meaning by what %. Best Regards, Michael Quote Link to post Share on other sites More sharing options...
Belle123 Posted August 8, 2016 Share #15 Posted August 8, 2016 Hello Billinghambaglady, How "magnified'? Meaning by what %. Best Regards, Michael My best guess, not very scientific, would be 25%. Or, slightly wider than 50mm equivalent M lens. Quote Link to post Share on other sites More sharing options...
ramarren Posted August 8, 2016 Share #16 Posted August 8, 2016 The marked focal lengths on lenses is often not exactly their true focal length. However, the difference you're suggesting seems more than normal. I'll check FoV between my Summcron-R 35 and Summilux 35 v2 when I get home ... I can do it on both SL and M bodies. Either the Summicron R is longer than expected or the M lens is wider than it ought to be. Quote Link to post Share on other sites More sharing options...
Michael Geschlecht Posted August 9, 2016 Share #17 Posted August 9, 2016 Hello Billinghambaglady, A few more questions, if you don't mind: What is the filter size of your lens? Is the lens hood built in or do you have to put it on? Best Regards, Michael Quote Link to post Share on other sites More sharing options...

This lens is probably first version. Serial 243xxxx Edited August 9, 2016 by billinghambaglady Quote Link to post Share on other sites More sharing options...
Belle123 Posted August 9, 2016 Share #19 Posted August 9, 2016 Mystery solved. I feel so dumb. All this time thought the R lens was a 35mm when finally screwed my head back on and looked at it and is a 50!!! OK to laugh. Ha! Quote Link to post Share on other sites More sharing options...
Michael Geschlecht Posted August 9, 2016 Share #20 Posted August 9, 2016 Hello Billinghambaglady, Does, by chance, the lens in question takes a Series VI filter & have a detachable lens shade? Best Regards, Michael Quote Link to post Share on other sites More sharing options...
