Attempting to 6-bit code Voigtlander lens

First I made the template and double checked with a coded Leica lens to be sure the locations for the white and black paint marks is correct.

Then I applied black marker at the correct locations for a Summilux 75mm lens.

When I mount the lens and turn on the M10-P is reads as R-ADAPTER-M. I assumed I did something wrong and removed the black and mounted the lens again with no markings on it and it still reads R-ADAPTER-M. Seems like strange behavior. Has anyone else noticed a Voigtlander 75mm Nocton reading as R-ADAPTER-M?

I would imagine you are among the first to try coding this lens. The day I get around to wanting to do this I’m just going to ask DAG if he would do it for me.

I've coded a summicron 35 asph correctly awhile back. wasn't difficult. this one has me stumped.

I also have the Voigtlander 75 Nocton, I did not code it. Did not get any weird behaviour from it. I manually selected 75mm summilux and that works so far. I did have one occasion where the wrong framelines showed up, but that seems to be a mechanical issue with the mount/flange of the lens.

Without manually selecting a lens does it say it’s R-ADAPTER-M?

If I turn lens detection off, it sais 'LD off'. If I set it to auto, it shows the last manually selected lens, summilux 75mm in this case.

So you applied the code 011100 i guess. What template did you use or reproduce if i may ask?

I think you need to use matt black paint irrespective of using a marker successfully in the past.

The R-Adapter-M thing is just the camera not recognizing the lens, not the camera imagining there is no lens attached. You can use it without coding but for the sake of a dab of black paint you may as well code it. The trouble with marker pens is that the black can still reflect light, it's a shiny black especially when built up in layers. The easy way is to use your template and the black marker to set the position and then fill the rebate in the flange with paint over the top. Depending where you are in the world small bottles or tins of matt black come under the brand names Testors, Tamiya, Humbrol, Gunze, and available from hobby shops.

I had a similar issue and making sure the black markings have a separation between them, even a thin one, solved the issue for me!

That was absolutely the problem. The marker did not work but black paint worked perfectly. I started another thread showing the steps I took to code the lens.
