pgk Posted June 16, 2021 Share #1 Â Posted June 16, 2021 Advertisement (gone after registration) Is it possible to 'cascade' adapters R-Adapter M (14642) and M-adapter-L (18771) and if so, will they work and transmit nformation in the same way, from lens to camera, like the R-Adapter-L (16076)?

Yes, if you’re using mechanically (2-cam and 3-cam) coupled R lenses. No, if you’re using electronically coupled R lenses. With the stacked R>M + M>L, the camera will recognize that you have an R>M adapter on but will not be able to know exactly which R-lens is mounted. The R-Adapter M does not have any electronic coupling. You’ll need to manually select the lens model attached for the camera to know. 1 Link to post Share on other sites More sharing options...
Photoworks Posted June 17, 2021 Share #3 Â Posted June 17, 2021 you can just like getting a generic R-to L adapter for $30 on amazon. Lens correction only apply when using R Lens with electronic contacts and Leica's R-to-L adapter you can still enter lens info to get sensor stabilization by selecting a focal length in the menu 1 Link to post Share on other sites More sharing options...
tedd Posted June 18, 2021 Share #4  Posted June 18, 2021 (edited) This is what I am doing, as 3 out of 4 of my lenses are M mount. I'm using the offical Leica M-Adapter-T, which is great, and was initially using a cheapo $30 R to M adaptor that didn't focus properly to infinity. I now use a Novoflex R to M that is built well, feels great to use and doesn't leave me worried that I'm crippling the performance of my super lovely 80mm Lux. By coding the R adapter (Novoflex comes coded) the camera at least knows that an R lens is mounted, which you can then select from a customisable list to apply corrections and EXIF data. As I only use the one R lens, the camera always knows which one it is. This was a great incentive for me to sell off my other R glass to minimalize gear and avoid confusion! EDIT::Added second paragraph.

You need to have the offical M to L (or T) adapter with the code reader on it and then use an R to M adapter with the R to M code applied. Eg:  Welcome, dear visitor!

pgk Posted June 18, 2021 Author Share #9 Â Posted June 18, 2021 Hmmmmm. I think that have the latest Leica M to L Adapter (I think that there was an earlier M to T - was it different in any way I wonder?)Â and was hoping that if I got the R to M then the camera would either read any ROM lenses or offer the R lens menu if it detected the R to M Adapter with a non-ROM lens. It sounds as though this may sometimes work (or as shown in the previous post with the Novoflex R to M Adapter). So it the Novoflex R to M a potentially better option than the Leica R to M? Is it worth contacting Leica to ask? Link to post Share on other sites More sharing options...
tedd Posted June 18, 2021 Share #10  Posted June 18, 2021 Note that my SL is the first gen and frame-it said that (s)he is using the SL2S. Not sure which model you're using but perhaps that's the issue. I do believe that to read ROM information you need the Leica R-Adapter-L and cannot stack them (as the M-Adapter-T/L only has a 6-bit code reader), but obviously I've managed to pull up the correct R menu in camera (and I've not owned a ROM coded lens anyway) with the two stacked units. Link to post Share on other sites More sharing options...

jaapv Posted June 18, 2021 Share #12 Â Posted June 18, 2021 How could stacked adapters work other than only registering that an R lens is used? - The M-(T)L adapters only read the 6-bit code just like an M camera. They can only "see" that there is an R-M adapter on - if it is coded. So there is no way that they can possibly transmit ROM information. To get an R lens into EXIF it must be entered manually which is possible as soon as the camera knows that there is an R adapter in the stack. To read the ROM information you need to use a R-L adapter. 1 Link to post Share on other sites More sharing options...

To read the ROM information you need to use a R-L adapter. So I suppose what I wanted to know is whether the M>L adapter can read and register that there ir an R>M adapter fitted to it and tell the camera this. So is there a 6-bit code which thells the M>L Adapter that there is an R>M Adapter fitted to it and does the M>L Adapter transmit this information to the SL (601) to allow access to the R menu and enable the r lens to be selected?

Spot on. This is what the Novoflex adapter I posted above does, though the offical Leica one does too and even that cheap $30 one that I started with had the mount milled so you could code it however you wanted. 1 Link to post Share on other sites More sharing options...
Photoworks Posted June 18, 2021 Share #16  Posted June 18, 2021 don't forget to ad the macro-adapter-M to the mix, you can stack does and it will be always a 90mm macro😆 1 Link to post Share on other sites More sharing options...
