One LCF Posted May 22, 2019 Share #1 Posted May 22, 2019 Advertisement (gone after registration) Hi all I'd like to purchase a Minolta M-Rokkor 40mm f2 to use on my M9 (which was adjusted to my Summilux 35 this March by Leica) to get an even lighter (and slimmer) travel kit. Apart from fungus, scratches and dust in the lens - do I need to worry about the focus being off? Thanks! Quote Link to post Share on other sites More sharing options...
Advertisement Posted May 22, 2019 Posted May 22, 2019 Hi One LCF, Take a look here Focus with a Minolta M-Rokkor 40mm f2 on a M9?. I'm sure you'll find what you were looking for!
lct Posted May 22, 2019 Share #2 Posted May 22, 2019 You mean M-Rokkor for Minolta CLE (not CL) i guess. Normally not but the fact that your camera has been adjusted for another lens may pose problem especially if the latter suffers from focus shift contrary to the Rokkor. 1 1 Quote Link to post Share on other sites More sharing options...

Correct, I'm looking for the later CLE version, since I read that the sloped focus cam of the first version is detrimental to a precise focus. Also the coatings are said to be improved with the later version. Quote Link to post Share on other sites More sharing options...
mdemeyer Posted May 23, 2019 Share #4 Posted May 23, 2019 The latter version has a straight cut rather than tapered focus cam. I have the early one and no problems on my M10. Can’t speak to the M9, however. Latter version might be safer... 1 Quote Link to post Share on other sites More sharing options...

With my Tele Elmarit 90 I already have one flare-queen in my kit... 😂 Quote Link to post Share on other sites More sharing options...
lct Posted May 23, 2019 Share #6 Posted May 23, 2019 Never got focusing issues with sloping focus cams on film or digital Ms so far. True for Leica C lenses (40/2, 90/4) and current 7art 35/2. I have no experience with the Leica M5 though. Quote Link to post Share on other sites More sharing options...
AceVentura1986 Posted May 24, 2019 Share #7 Posted May 24, 2019 Advertisement (gone after registration) Do the two versions have distinct markings so as to distinguish them? If not, then how can you tell? Quote Link to post Share on other sites More sharing options...
Ko.Fe. Posted May 24, 2019 Share #8 Posted May 24, 2019 I've had 40 CLE version on M-E. Not a problem, if not better than 35 lens for 35mm framing. Sharp on f2. Welcome, dear visitor!

If not, then how can you tell? The earlier version (CL; with sloped cam, single coating) had marked its serial number on the front ring, like Leitz / Leica lenses are marked. The later version had its serial number on the lens barrel (CLE; with even cam, multicoated), so no serial number on the front ring.

It isn't Leica normal policy to adjust a body to a lens although I'm sure it could be overridden. What happens when focus is off is Leica ask for both the lens and body to be sent to them so they can check which is out of spec and adjust it back to its original tolerances. This is so another variable isn't introduced as would happen if the body was adjusted to the specific lens. So if Leica have done their normal job using another lens shouldn't be a problem and focus will be accurate if the other lens is also within tolerance. 1 1 Quote Link to post Share on other sites More sharing options...

Actually I'm not sure whether Leica adjusted the camera body or the lens. As you mention, adjusting a camera body to an out-of-spec lens would be counter-productive, as other (in-spec) lenses would show focus errors. 1 Quote Link to post Share on other sites More sharing options...

Additionally the newer CLE version is labeled with "M-ROKKOR", while the old CL version with "M-ROKKOR-QF". 1 Quote Link to post Share on other sites More sharing options...
g2van Posted June 1, 2019 Share #15 Posted June 1, 2019 I have the later version of the CLE for my M10 and it is a tiny and superb lens. Mine was "shaved" to activate the 35mm framelines which I prefer. The CLE version is easier for filters because it's a common 40.5mm. Quote Link to post Share on other sites More sharing options...
