ryan_peck Posted June 12, 2007 Share Posted June 12, 2007 Is there any way to encode my lenses myself to avoid sending my lenses to Leica for 6-bit encoding? If so, how? thanks ryan Link to comment Share on other sites More sharing options...

james mitchell dc Posted June 12, 2007 Share Posted June 12, 2007 Ryan, this is a great link. Some lenses are easier than others. I did a Zeiss 28/2.8, a Leica 24/2.8 ASPH and two 35 'crons: v4 and ASPH, but have failed with a 35 lux ASPH. With my two coupons, I'll probably get the 35 lux and another lens done by Leica when they seem to be running at a reasonable pace. Link to comment Share on other sites More sharing options...
andy_piper2 Posted June 13, 2007 Share Posted June 13, 2007 Yes, with a Sharpie and with the code list linked above. However, some lenses have a screw head in the area where the coding goes that can screw up (wink!) the reflectivity and thus the reading. I tried coding a 28 and it came out variously as a 21 or a 90. For screw mount lenses, a guy named John Milich is now offering specially machined LTM- M adapters with the 6 little pits already engraved into the mount, so all one needs is some black and white enamel to do a nice permanent no-rub-off coding. Good for the 15mm C/ V (which can be coded as a 16/18/21 to get the right optical corrections with an IR filter), as well as any other LTM lens (Canon, C/V, etc.). You'll find discussion of these mounts at the Leica Users' Forum. Link to comment Share on other sites More sharing options...
clyde_rogers Posted June 13, 2007 Share Posted June 13, 2007 John Milich also will cut those six little channels in your Leica lens flanges for $25 per flange. You fill them with paint based on Carsten's coding guide, and have a durably coded lens. You must remove, reinstall and code the flanges yourself (the removal at least is easy---I sent several flanges to him last week). I'll post again when the flanges are back, and report on quality of work and time taken. --clyde Link to comment Share on other sites More sharing options...
james mitchell dc Posted June 14, 2007 Share Posted June 14, 2007 I finally succeeded with the 35 'lux ASPH. You have to be very exact with that one. Now all of my wide angles are coded except the CV 15 and Kobalux 21--both of which need a wider LTM adapter. I might consider getting some flanges machined. Please let us know your results, Clyde.

clyde_rogers Posted June 15, 2007 Share Posted June 15, 2007 Okay, the short answer is that John Milich does excellent work, send him your flanges. I sent John three lens flanges (35 cron, 21 elmarit, and 90 cron) last Friday, priority mail. I got the flanges back yesterday (Thursday) priority mail, so a six day turnaround including shipping (John is in NYC, by the way). The flanges are exactly as before, just with six small pits milled into them. The pits are very cleanly and uniformly cut, likely with a CNC milling machine. The ends of the pits are semicircles, while the Leica pits are more squared off. Otherwise, they look just like the Leica pits. I filled in the pits as described in Carsten's guide with flat black and gloss white paint last night (it's what I had on hand), let it dry for an hour or so, and scraped off excess with a box cutter blade. I used trimmed down 29 cent paintbrushes to apply the paint. I let it dry overnight, and reinstalled the flanges. One point---on many lenses, if you just tighten down the flanges, you get some slight binding on focusing. Tighten the flange snugly, and back of each screw a quarter turn or so. Then focus the lens through its travel several times, and without touching the flange, snug up the screws, and then tighten them fully. This has made every one of my lenses focus perfectly smoothly. Anyhow, all the lenses are recognized just as if they had Leica flanges. The coding is clean, professional looking and effective. Coding for three lenses cost me $75, plus $20 for insured priority return shipping (regular mail shipping costs nothing extra), and took exactly one week start to finish. Email jm at milich dot com for details. He's responsive, and his work is highly recommended. --clyde Link to comment Share on other sites More sharing options...
clyde_rogers Posted June 15, 2007 Share Posted June 15, 2007 Oh, and James, I also got one of John's LT-M8 adapters. It's a very nice adapter with coding pits neatly machined into it. My CV 15 is now recognized as a wide angle tele elmarit on the M8. These adapters are expensive ($150), but are well made, and function exactly as they should. Until later, --clyde Link to comment Share on other sites More sharing options...

o._refetoff Posted July 27, 2009 Share Posted July 27, 2009 <p>Clyde gave John Milich's email above, but here is is again: jm@milich.com<br> John often responds within a day or two, but he is a photographer and sometimes away on work.</p> Link to comment Share on other sites More sharing options...
