Re: TTartisan Leica M to Sony E adapter with 6-bit code
Good to hear that my workaround is useful for others as well
I found one limitation to it so far. While the workaround has been applied and a lens that has a "6-bit code misreading issue" is staying on camera (& fl is set correctly via the workaround), if you try to charge the camera via USB-C with camera turned off, and then stop the charging and turn the camera back on, the 6-bit code gets misread again and the effect of the workaround disappears, so that it becomes necessary to reapply it. I tested this with a very short charging time of a couple of seconds and it effectively wiped out the workaround and caused the 6-bit code to be read again.
There might be some other conditions where the workaround gets lost as well. I'm going to test if it is still effective after a longer power-off time (such as all night etc.) as long as charging is not done...
On other news, I found out that my CV 50/2 Heliar classic that had the 6-bit code misreading problem on my earlier tests can be quite easily connected to the TTArtisan adapter so that the hole where the pin on the adapter is supposed to click into is moving further (counterclockwise) than the pin's position and the pin doesn't click into place, although the lens is sitting tight on the adapter. If I make sure the pin is clicking into place precisely, there is no misreading of 6-bit code anymore with this lens. On the other hand, my M-Rokkor 40/2 still always has the misreading problem even though the pin is clicked into correct place.
