coding vintage lenses

Recommended Posts

No.  Home coding does not always pick up with new M camera.   

 

50 and longer generally are fine.

 

28 might benefit if you have an issue corner fix  can not correct.

I'd be coding them purely for the EXIF info if nothing else.

The LTM ones are simple, obtain the appropriate adapter with the 6 bit coding pits already milled in place. I had one on a Canon 50/1.4.

I'm looking for a new M mount for my Rokkor 40 and the voigtländer Ultron 28 with coding pits, but I struggled to find one with the correct screw holes... Any tips where and who to buy the correct one without try--error over and over again.

We go along for a century without lens being recorded.   Do not expose yourself to trouble.

 

If you do not believe me,  do a hand code and then send it to DAG with instructions on how to code.

 

I coded some older lenses with new mounts and when comparing to real Leica factory coding,  the pits  are different.

 

Also if you code to crop and move up later,  the correction my not be optimal.

I would be reluctant to exchange the original mount flange with an aftermarket item, not trusting the precsion... Further, I want to make sure the older lens is "tuned" to the digital sensor, so that calls for a trip to DAG. He has the original flange machined and put back with focus adjustment. Reassuring to have it done right. He's done several older Leica lenses for me, as well as newer Zeiss and Voigtlander, very satisfied with the results.

The flanges I purchased from China do not always focus correctly.   My micrometer told me they we too thick by .001.   Some emory paper and judicious grinding fixed that.   

 

What I can not fix is the pits are different size than Leica pits visually.  They work ok,  but perhaps that is why some report they do not work on M240.
