jlm Posted June 8, 2007 Share #1 Posted June 8, 2007 Advertisement (gone after registration) anyone have one of these filters from Leica? I need the diameter and thickness of the glass to make sure it will fit the up-coming adapter, which was sized based upon a Tiffen 55mm UV filter glass. I'll post a pic of the adapter later today. jm Link to post Share on other sites More sharing options...
Advertisement Posted June 8, 2007 Posted June 8, 2007 Hi jlm, Take a look here C/V 12mm and 55mm UV/IR filter. I'm sure you'll find what you were looking for!
Guest guy_mancuso Posted June 8, 2007 Share #2 Posted June 8, 2007 John i will bring my 12mm next week to NY when I see you , maybe I can get lucky and find a 55mm IR leica filter . But OT for a second, I'm a a little pissed about my 12mm first my hood broke , so i super glued the sucker on, it works. Next i noticed my front element coating is really weird and marked up, needless to say that is the LAST time i buy something from e-bay. People sell there junk there more times than not and i am done with it. Feel like I wasted close to 600 bucks because there is no way l will sell this to someone. I'll show you next week, okay back to my sleepless work project. 14 hours sleep in 3 days has made me pretty darn grumpy. LOL Just had to vent a little Link to post Share on other sites More sharing options...
sean_reid Posted June 8, 2007 Share #3 Posted June 8, 2007 Hi John, People will also be using the 55 mm 486 filters as well. I'll get one apart and measured for you as soon as I can. Cheers, Sean Link to post Share on other sites More sharing options...
jlm Posted June 8, 2007 Author Share #4 Posted June 8, 2007 the near-finished product. the mounted adapter is only painted and has the Tiffen UV glass and shows a few bright spots in the finish that will not be in the final product. next to it you see the as-machined adapter and retaining ring, the material is aluminum and the final finish will be black anodized with a matte finish inside the grooved surface of the hood. the adapter is retained on the lens with either a thumb screw or a set-screw, both provided. the glass is from a 55mm filter and is set as close as possible to the lens element without touching it. there is no vignetting that I could see. Sean will be wringing it out next week. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

I was lucky and snagged a Leica 49mm UVA/IR filter from someone that received it in error. The results are excellent . I guess the CV 12 will be next on my list. I also like your Luigi case ..I selected the same one. Roger Link to post Share on other sites More sharing options...
psquared Posted June 9, 2007 Share #7 Posted June 9, 2007 Advertisement (gone after registration) John, Looks great! What's the outside diameter of the hood? Wonder if there's a 3rd party slip-on cover for that. Peter Link to post Share on other sites More sharing options...
valtof Posted June 9, 2007 Share #8 Posted June 9, 2007 the near-finished product. the mounted adapter is only... Hi John, I also use the CV12 on the M8. I have 6bit-coded it as a WATE with a bit of machining on a 90 Leitz adapter and enamel paint, and it works fine. I'm amazed that you could have elaborated a special adapter to provide this lens the possibility of mounting the IRcut filter without going into the CV 77mm adapter solution, which I find too obstrusive and fragile for the very expensive 77mm filter, not being protected by any hood or whatsoever in front of it. I suppose that's the reason you did so. Am I wrong? Congratulations anyway. Question 1 : do this adapter will be available for us at LUF in any manner (also of money may be)? I'm really interested if so, of course. Question 2 : I read (and saw a picture) in other threads that you have also produced special adapters already machined for 6bits coding. Is that right ? I would be interested to get one or two for my only lenses I can't code myself. These are two Canon 50mm (1.2 and 1.4) and if I'm not wrong, I don't think any 50 adapter without cutout do exists. Thanks by advance for your answer. Cheers Christophe Link to post Share on other sites More sharing options...
jlm Posted June 9, 2007 Author Share #9 Posted June 9, 2007 the od of the adapter is 68mm. e-mail me for purchasing details for this and other adapters. I may make a filter adapter for the 15mm C/V lens as well; maybe the same 12mm adapter with a different bore to fit over the fixed 15mm hood petals. jm@milich.com Link to post Share on other sites More sharing options...
sean_reid Posted June 19, 2007 Share #10 Posted June 19, 2007 John sent me a test copy of the (first version) CV 12 filter adapter and it was well-made as always. I suggested a couple of changes to it, however, and John is working on a new and improved version.The new version will allow one to thread a filter directly into the adapter (no need to remove the filter glass or install a retaining ring) and it will, I believe, feature a hood that provides more aggressive lens shading than did the first version. I also suggested a design for a CV 15 filter adapter that John is working on as well. It features a sleeve that the existing CV 15 hood slides into. and it also will allow a filter to be threaded into it directly. Cheers, Sean Link to post Share on other sites More sharing options...
stephengilbert Posted June 19, 2007 Share #11 Posted June 19, 2007 SKGrimes will make custom caps (http://www.skgrimes.com/caps/index.htm); you need only provide the OD and the depth you want. Their prices vary with size, but I think they'll give a discount for multiple orders of the same size. Maybe enough people would be interested to get a "deal." You can find a phone number on their website. Link to post Share on other sites More sharing options...

Guest sirvine Posted June 20, 2007 Share #13 Posted June 20, 2007 John, I think you mentioned this recently, but I have been traveling: are you making (planning to make) a similar filter adaptor for the 15mm? Thanks, Sol Link to post Share on other sites More sharing options...
jlm Posted June 20, 2007 Author Share #14 Posted June 20, 2007 I expect to have the new 12mm version and the 15 out in a week or two. jm Link to post Share on other sites More sharing options...
