hejenk Posted September 5, 2013 Share #1 Posted September 5, 2013 Advertisement (gone after registration) Like most of us I am bemused why the new R to M adapter has not yet been released.While waiting for my Leica M, I bought a couple of R lenses to use on my new M. I also bought an uncoded adapter. However I seem to be unable to code this adapter. I have seen the code 110111 which I presume is the correct code displayed in images in the Forum as both 3 black and also 2 black first then a gap and the other blacks. I also have a Coder kit. I'm sure there is a simple way to do this but I haven't found it yet! I would prefer to have Leica's own adapter but in the meantime ... Any suggestions please? Thanks Hugh Link to post Share on other sites More sharing options...

gravastar Posted September 5, 2013 Share #2 Posted September 5, 2013 I have a Leitax adapter for some of my R lenses. Although it has the coding slots I've been unable to get it recognised by the M(240). I've made sure the black and white paint I've used is opaque to infrared. The type and layout of the coding sensors on the M(240) are different than those of the M8/9. I believe it's been previously reported that the M(240) appears to be more finiky about coding tolerances than the earlier cameras. Bob. Link to post Share on other sites More sharing options...

01af Posted September 5, 2013 Share #5 Posted September 5, 2013 However I seem to be unable to code this adapter. I have seen the code 110111 which I presume is the correct code displayed in images in the Forum as both 3 black and also 2 black first then a gap and the other blacks. The 6-bit code must be read from left to right, as we write, when looking at the back of the lens and the code is at the 12 o'clock position. A '1' represents a black patch; a '0' is a white patch. So it's two black patches, followed by a white patch (or just a blank when the bayonet flange surface is white metal), followed by three black patches. Each patch is two millimeters wide. Furthermore, normally the camera accepts a 6-bit code only when the framelines selected by the lens match the coded lens. For example, if you code a Zeiss 35 mm lens as "Summicron-M 50 mm" then the camera will reject the code because it says, "50 mm," while the lens does not actuate the 50 mm framelines. However, the R-Adapter-M is an exception. The original Leica adapter actuates the 28/90 framelines but the camera will also accept a coded adapter that actuates the 50/75 framelines (which is what the Novoflex adapters do). But then, I don't know if the camera will also accept the 35/135 framelines. So if your adapter uses the 35/135 framelines then maybe that's the reason why your do-it-yourself code doesn't work ...

algrove Posted September 5, 2013 Share #7 Posted September 5, 2013 Advertisement (gone after registration) I can't get mine to work by hand coding it. I suspect it's because in mostly the fifth position is a screw. The screw also touches the edges of positions 4 and 6. Link to post Share on other sites More sharing options...
jaapv Posted September 5, 2013 Share #8 Posted September 5, 2013 My coding works, but was machined in. Link to post Share on other sites More sharing options...
algrove Posted September 5, 2013 Share #9 Posted September 5, 2013 Was the mount ring changed so there is no screw in the way? Link to post Share on other sites More sharing options...
thighslapper Posted September 5, 2013 Share #10 Posted September 5, 2013 The current Novoflex LEM/LER comes pre-coded and is recognised immediately by the M as R-Adapter-M on the info screen. Got fed up waiting for the Leica adapter. Having not used my Nikon gear for many years I now find I am too puny to use the M with my 280/2.8. Must spend some time in the gym......

thighslapper Posted September 5, 2013 Share #13 Posted September 5, 2013 Interesting, when I got my novoflex adaptor a month ago it was not coded:(. Is yours machined or just inked? No...... it has drilled black pits and a correctly sized white stripe as per normal six bit lens coding in the right place..... it's very difficult to tell if it is recessed or just painted on.... so it's hard to tell whether it will survive repeated removal/attachment I too was surprised when it arrived earlier this week and found it worked straightaway......

lawman Posted September 6, 2013 Share #15 Posted September 6, 2013 thighslapper - any idea why the black bits are drilled and the white is a milled line? I thought that the only key marks are the black ones. Has anyone else managed to get black marks drilled and recognized as black bits by the M? If so, what size drill bit did you use? I have three Jin flanges which work perfectly with the M9 and are not read at all by the M. Link to post Share on other sites More sharing options...
jaapv Posted September 6, 2013 Share #16 Posted September 6, 2013 It seems to me like a patent workaround, this differs from Leica's bars. If the camera will see a screw as a black mark, which it does, it will see a drill hole as a black mark as well. Link to post Share on other sites More sharing options...
jaapv Posted September 6, 2013 Share #17 Posted September 6, 2013 Me to but it did not help.You need to use matte paint.The screw is offset to the reading LED, so it must be partly white, partly black. My coding is certainly not pretty, but it works. Link to post Share on other sites More sharing options...

Very interesting! Mine looks like this: Got the white stripe in right position but I'm missing the drilled holes , unfortunately it does not get detected by the M either.

How does the list of R-lenses look like on the camera screen when you engage the adapter? I seem to get the lising of M-lenses only. Link to post Share on other sites More sharing options...
