roguewave Posted April 23, 2010 Share #1 Posted April 23, 2010 Advertisement (gone after registration) I have both the Rokkor & Summicron 40. Both great lenses. I prefer the Rokkor. Can either be coded for the M8/M9? If I shave the Rokkor to bring up the 35 lines does that adversely impare the effects of the coding? Link to post Share on other sites More sharing options...
Advertisement Posted April 23, 2010 Posted April 23, 2010 Hi roguewave, Take a look here Can the 40 Rokkor or Summicrom be coded 4 M8?. I'm sure you'll find what you were looking for!
ho_co Posted April 23, 2010 Share #2 Posted April 23, 2010 Ben-- Long answer: 1) Since the lenses aren't recommended for M cameras, I doubt it. 2) As of January 2009, Leica's published list didn't include either lens (http://en.leica-camera.com/assets/file/download.php?filename=file_4066.pdf). 3) There is no code established for them. (See Carsten's Leica M Lens Codes.) 4) Would coding be of optical benefit with the lenses? Obviously the EXIF would be wrong. 5) Once you determine how you want them coded, I'm sure you can find someone to do it. That's assuming that none of the mount screws is in the way, as is the case with some of the uncodable M lenses. Which frame line is brought up by the lens may or may not make a difference, depending on how you decide to code it. In many (all?) cases, the frame preview lever position must match the lens code. Short answer: Since neither you nor I have ever heard of it being done, you probably don't need to do it. Link to post Share on other sites More sharing options...
jaapv Posted April 23, 2010 Share #3 Posted April 23, 2010 Yes, you can code them as 50 if you like. If you shave it you must code it as 35. A screw in the way is no problem, you can paint it in, either black or white, as the case may be. Link to post Share on other sites More sharing options...
lct Posted April 23, 2010 Share #4 Posted April 23, 2010 There is a screw in the way on both the Cron & the Rokkor i'm afraid. Should be painted in white apparently but i have no experience of this. Link to post Share on other sites More sharing options...
jaapv Posted April 23, 2010 Share #5 Posted April 23, 2010 Yes - I have an Elmarit 28, with a screw over the diodes. Painted half black, half white. No problem. The persons machining the indentations (I suppose for Ben that would be John Milich) will machine around the screw. Link to post Share on other sites More sharing options...
ho_co Posted April 23, 2010 Share #6 Posted April 23, 2010 Jaap-- Tell me more. You apparently have the same 28 as I, which I found useless uncoded on the M8. So, I take it, you had a machinist machine the depressions into the mount? Then you reassembled the lens and hand-painted it? Which 28 did you code it as? Just one more: I had been thinking I could salvage the lens by getting an M9, leaving the lens uncoded, and letting the camera apply 'base' corrections. If you have opportunity, could you tell me how the M9 works with the lens with lens ID off? Many thanks!!! Link to post Share on other sites More sharing options...
jaapv Posted April 23, 2010 Share #7 Posted April 23, 2010 Advertisement (gone after registration) On the M9, With lens ID off, it vignettes, with lens ID on, either in menu or through coding it is surprisingly good. I am quite happy with it. I just sent it to my favorite repair facility and got it returned coded. It is a third version btw. Link to post Share on other sites More sharing options...
ho_co Posted April 23, 2010 Share #8 Posted April 23, 2010 Thanks. Don't know which version mine is, maybe version two? It's the first one that could meter with the M5. How is yours coded? I guess I need to play, since Carsten shows four different options. Link to post Share on other sites More sharing options...
jaapv Posted April 23, 2010 Share #9 Posted April 23, 2010 Four whites, two blacks. Link to post Share on other sites More sharing options...
ho_co Posted April 23, 2010 Share #10 Posted April 23, 2010 Thanks. I was just coming back to cancel the question, since if you've got a version III, you'll obviously code it as a version III. Duh... Link to post Share on other sites More sharing options...
jaapv Posted April 25, 2010 Share #11 Posted April 25, 2010 Whatever version, these lenses are fine on the M9. I went out and took this test shot today: Welcome, dear visitor!

jaapv Posted April 25, 2010 Share #13 Posted April 25, 2010 Yes, it is coded. It makes no difference if you select it in menu, however. Link to post Share on other sites More sharing options...
lct Posted April 25, 2010 Share #14 Posted April 25, 2010 Otherwise there is some vignetting i guess, right? Link to post Share on other sites More sharing options...
jaapv Posted April 25, 2010 Share #15 Posted April 25, 2010 Yes, quite a lot of vignetting, actually. Link to post Share on other sites More sharing options...

thinkfloyd Posted April 26, 2010 Share #17 Posted April 26, 2010 Ok, rather than create a new thread, I'll just ask my question here... I own a 35/2.5, 50/1.2 and 75/2.5. However, I find myself using the 35mm 95% of the time, with the 50mm the other 5% only if it's super low light shooting. Now, I just want to use a single lens. Both for simplicity's sake and because I can't afford unused lenses (though the 35 and 75 are CV lenses). For the 40 Summicron owners out there, is it feasible to just sell all my lenses and use the 40mm exclusively? I don't really like the images I get with the Nokton 40/1.4, though the speed is welcome. I don't have money for the 35/1.4 summilux ASPH (which would be the perfect one lens kit for me) or even the 35 summicron (v4 or ASPH). Or should I just keep the 35/2.5 and live with the slow speed?

The best lens maybe the 35 Summilux pre asph. Sell for arounf $1,000 US. One of the all time greatest Leica lenses. I have both 40's & they are superb, but the frameline issues, filters, etc may put you off. I love both of the 40's & use them with all my M's: M2, M3, M8 & CL.

thinkfloyd Posted April 26, 2010 Share #19 Posted April 26, 2010 Thanks for the reply Ben... my issues with the 35 pre-ASPH is the minimum focusing distance. I tend to shoot mostly close-up... besides, $1000 is still kinda expensive for me What about the 35/1.4 nokton? I read it has a classic look and although it has slight distortion, is relatively sharp... Link to post Share on other sites More sharing options...
lct Posted April 26, 2010 Share #20 Posted April 26, 2010 The CV 40/1.4 is a very good lens so if you don't like what you get with it i would keep a 35 if i were you. I only use 3 of them in the M format: the pre-asph Summilux 35/1.4, the Summicron 35/2 IV and the CV 35/1.4 SC. The best affordable compromise would be the latter which IQ is close to that of the pre-asph Summilux plus more sharpness at f/1.4. Problem is it flares a lot and i have focus shift issues with it. But there are sample variations at CV so you could perhaps try a couple of SC and MC copies of this lens before deciding. Link to post Share on other sites More sharing options...
