rtai Posted January 28, 2022 Share #1 Posted January 28, 2022 Advertisement (gone after registration) I already have a Leica M mount to L adapter. I also want to use R lenses on the SL2. Is there a reason to buy the very expensive Leica R to L adapter rather than just mounting the R lens to the M adapter and then add the M to L?

Advertisement Posted January 28, 2022 Posted January 28, 2022 Hi rtai, Take a look here Is there any advantage to getting an R to L over separate R/M and M/L adapters. I'm sure you'll find what you were looking for!

If you want the SL2 to detect the R lens via ROM contacts, assuming it has ROM contacts, then you’d need the R to L adapter. 1 Quote Link to post Share on other sites More sharing options...
rtai Posted January 28, 2022 Author Share #3 Posted January 28, 2022 Thanks on the info about the vignetting. I’ll just get a Metabones R to L adapter. The Leica one is quite pricey. Quote Link to post Share on other sites More sharing options...
jrp Posted January 29, 2022 Share #4 Posted January 29, 2022 The Leica adapters are priced ridiculously but you can check https://www.lensrentals.com/blog/2013/09/there-is-no-free-lunch-episode-763-lens-adapters/ https://www.lensrentals.com/blog/2017/03/mixing-camera-systems-our-guide-on-how-to-use-adapters-properly/ from which I conclude that adapters are not a panacea and that using 2 of them may or may not help. But it depends on how much you care about micro contrast. Quote Link to post Share on other sites More sharing options...
caissa Posted January 31, 2022 Share #5 Posted January 31, 2022 (edited) Metabones is definitely worse than the two options you mention. I’d get a Leica R to M adapter. I use this combination of adapters since several years successfully. (And feel no need for the intelligent single adapter.) (And metabones is as dumb as dumb can be, and not even very precise.) Metabones is probably one of the worst types. Novoflex is probably the best non-Leica option. The vignetting is not a great problem. It affects only lenses like the old 560mm, which is not a top lens in modern eyes anyway. Edited January 31, 2022 by caissa 1 Quote Link to post Share on other sites More sharing options...
