I wouldn't complain.

This is the behavior I certainly want, namely bringing up the lens menu no matter what the frames lines are.

FD 300/4 L

FD 85/1.2 L

FD 35/2.8 TS

 

The FD 50/1.4 is not interesting given its definition compared to the Summilux 50/1.4 ASPH.

 

Bert, those lenses sound perfect for filling in where Leica leaves off. I saw a used 85/1.2 Eos lens and wanted to adapt it knowing it was only usable at f1.2 however the focus is controlled electronically and can't be used on non-Canon bodies.

I have just tested today with my newly arrived replacement M240 and a Kippon R to M adapter. The framelines tab on this is totally ground back, so that it leaves the framelines in their rest position i.e. 35/135mm. I have hand coded this 110111. As I expected, it cannot bring up the R lens menu and the code is not recognised. I have not got an adapter which brings up the 50/75 framelines, to test if 55-2 works or not. My other hand coded adapter a Contax CX/Y to M, which does bring up the 28/90 framelines, immediately brings up the manual lens setting menu on the LCD, when you press menu and allows me to access all the R lenses.

Is it totally out of the question that you possibly may have mis-placed the code by 0.5 - 1 mm? The code patches must be positioned very precisely, or they won't tbe recognised.

Well—assuming the hand-made coding on your Kipon adapter is positioned properly, you've just proven that 55-2 does not work.

 

We all know that 55-1 works (because that's the original Leica R-Adapter-M's own code), and we also know that 55-3 works (because several forum members—including myself—have tried and verified this through hand-coded Novoflex adapters).

I agree with 01af. My Novoflex brings up 50/75 framelines but coded shows up in the M240 menu as Leica R-adapter M and allows lens selection. From my past limited experience with hand coding, I would also suggest matte white rather than gloss white for the appropriate place. I remember having a lens that had glossy white dots not being recognized, but when I changed to matte worked fine.

Olaf,

 

My Kippon adapter has coding grooves milled in it. I checked their positioning with my Coder-M, where they appeared to be spot on, as it is quite common for these grooves to be out of position on third party adapters (they are on my Leitax R to M and Muscelli Contax RF to M adapters). I also have noticed that the M240 is much fussier on coding groove position than the M9. I used the normal Pentel Sharpie pen that has worked for years for the black slots and Tippex in the #3 white slot. Now what I do wonder if the fact that the framelines tab is ground right off makes a difference. It is certainly ground back far further than the framelines tab on my Leica 35 ASPH Summilux.

So I guess we can assume the position is fine.

This might possibly make a difference indeed. So I'm afraid we still don't know entirely for sure whether the 55-2 code (with a proper frameline tab) will work or not. At least we do know that the Leica M (Typ 240) happily accepts the 55-1 and 55-3 codes—i. e. the 28/90 and 50/75 framelines.
