biglouis Posted April 8, 2008 Share #1 Posted April 8, 2008 Advertisement (gone after registration) Has anyone else had this happen? I've set my menu option to "Lens Detection On + UV/IR" as my lenses coded. Yesterday, I added a CV 50/1.5 to my collection. I did not think it worth changing the Lens Detection option, the 50/1.5 does have a UV/IR filter on it. Anyway, looking through the results of my CV50 in Lightroom, on an inconsistent basis the image is reported as having come from a 50mm lens. How is this possible? It the camera somehow detecting the frame lines and guessing at the 50mm focal length? LouisB Link to post Share on other sites More sharing options...

bayerische Posted April 8, 2008 Share #2 Posted April 8, 2008 Is this the lens with a screw head just in the right position to get it recognised? Link to post Share on other sites More sharing options...
jaapv Posted April 8, 2008 Share #3 Posted April 8, 2008 If it is on a CV adapter, the adapter will have a cutout over the diodes, admitting intermittent stray light. That can trigger the lens detection. Finally Leica stands vindicated with their admonition in the manual to switch of lens detection on uncoded lenses to avoid malfunctions!

Well, if it is a malfunction it is very odd that it has chosen the correct focal length. Don't know about the location of the screw. I was thinking about manually coding the lens LouisB Link to post Share on other sites More sharing options...
Guest rweisz Posted April 8, 2008 Share #5 Posted April 8, 2008 If it is on a CV adapter, the adapter will have a cutout over the diodes, admitting intermittent stray light. That can trigger the lens detection. Bingo. If you keep the detection on, you really need the old Leitz adaptors (or the new Cosina one's) that just have 3 half-moon cutouts. And, you also need to watch for crud on the lens mounts. A black grease smear can fake out the detector too. Link to post Share on other sites More sharing options...
cbretteville Posted April 8, 2008 Share #6 Posted April 8, 2008 CV's type II LTM-M adapters does not have the cutout and are great ($55 from Cameraquest). They're easy to hand code. Can be milled for permanent coding. An alternative is John Millic's LTM8 adapter a bit more expensive, but is already milled when you get it. - Carl Link to post Share on other sites More sharing options...

Look for auctions by yau38 Hmmm. Just got the price list from John Milich and his adaptor plus shipping to the UK is $130. I think I'll go with John as he has the established reputation in this field. LouisB Link to post Share on other sites More sharing options...

Michael Tyler Posted May 24, 2008 Share #11 Posted May 24, 2008 FWIW, I have the same setup going, except the adapter is the Leica brand instead of the CV. It also recognizes it as a 50mm lens in the exif data. Link to post Share on other sites More sharing options...

Package came fromYau Wai Kin 238 Keong Saik Road Singapore 089130 tel: 65-6221 3445 He machines a stock Voigtlander Type II adapter, whereas I understand Mr Milich makes one from scratch.

cbretteville Posted May 25, 2008 Share #13 Posted May 25, 2008 John Millich will machine the grooves in adapters and lens flanges (provided you remove them from the lens first) too. He's done a couple of old Leitz adapters for me. - Carl Link to post Share on other sites More sharing options...
Hacker Posted May 25, 2008 Share #14 Posted May 25, 2008 "Yau38" has no items listed on eBay at the moment. He machines a stock Voigtlander Type II adapter, whereas I understand Mr Milich makes one from scratch. I have bought I think at least 10 adapters from him, so no issue. I switched after the shipping charges from JM were too much. He codes the adapters for me before sending them my way. Anyway, the free Voigtlander caps are also an incentive for me.

jlm Posted May 26, 2008 Share #15 Posted May 26, 2008 just to clear the record, the adapters I make, which include the coding recesses, were developed about a year before C/V finally put an adapter, without the cutout and without the coding recesses, on the market. When they did, I lowered my price to $100 plus international shipping cost. If you want one of the new style C/V adapters machined for the recesses, that is $25 plus international shipping. no shipping charge for USA deliveries in either case. jm@milich.com Link to post Share on other sites More sharing options...
