Monochrome Posted April 5, 2016 Share #1 Posted April 5, 2016 Advertisement (gone after registration) I shot some pictures yesterday for the first time with my M262 and the Elmar 24/3.8. In almost every shot there was a slight magenta cast on the sides. It is clearly visible in the skies and also in the mid grey areas. I tried it with both the lens profile on automatic and off, but this made only a small difference. The magenta doesn't show up with my summicron 35/2 or 50/2 when i shoot the same subject, so it must have to do with the Elmar. Is there an easy solution for this problem besides removing it in Lightroom? Is this problem also there with other wide angle lenses on a Leica M? hope someone knows the answer to this.

Is there an easy solution for this problem besides removing it in Lightroom? Is this problem also there with other wide angle lenses on a Leica M? hope someone knows the answer to this. I thought this sounded odd, so I had a look. In looking at my M240, I find no in camera profile for this lens with firmware 2.0.2.5, although a code has been issued. This doesn't seem to make sense as in spite of the lens being 6 bit coded I only see a 24mm/f2.8 in the camera. Presumably the M 262 lacks one as well. Does it say 24/3.8 on the screen and in the exif ? Lacking a profile the camera can't make the corrections on it's own. Perhaps experimenting manually with the other profiles and see if one works. I noticed someone suggested using the Elmarit-M 24/2.8 profile on the M9. Might be worth a look. Welcome, dear visitor!

dkmoore Posted April 6, 2016 Share #3 Posted April 6, 2016 I own this lens and do not experience magenta color cast but I use the M-P240. I doubt there are any intended manufacturing differences between the M-P and 262. I am not technically aware of any adjustment issues with the lens that would create this issue. Maybe post a picture taken with your copy so we can see an example and make a better determination? Link to post Share on other sites More sharing options...
lct Posted April 6, 2016 Share #4 Posted April 6, 2016 It has to do with the 24/3.8 profile that is almost useless with the M240 so i suspect it is the same with the M262. Doesn't mean that the profile is lacking though. Lenses coded from scratch don't need a manual profile since they are all recognized by the camera. It is the case for your 24/3.8 but also for latest asph lenses like 18/3.8, 21/1.4, 21/3.4, 24/1.4, 24/3.8, 35/1.4 FLE, 50/0.95 and 50/2 apo IINW. As far as the M240 is concerned, the 24/3.8 is supported by Leica since firmware update 1.1.0.2 in Marsh 2013. Link to post Share on other sites More sharing options...

This is what I would have expected. Imagine my surprise finding the profile does not appear on my camera M240 M-P. Am I misunderstanding something ? Welcome, dear visitor!

lct Posted April 6, 2016 Share #6 Posted April 6, 2016 I don't think so, as i suggested above some lenses have no manual profile because they are coded from day one so that all their copies are recognized automatically by the camera. Their name doesn't appear in the list of manual lenses then but their automatic profiles are implemented in the camera most probably. You may wish to try different manual profiles if the automatic one does not suit you. Many users prefer that of the 24/2.8 asph AFAIK. Link to post Share on other sites More sharing options...
jonoslack Posted April 6, 2016 Share #7 Posted April 6, 2016 Advertisement (gone after registration) This is what I would have expected. Imagine my surprise finding the profile does not appear on my camera M240 M-P. Am I misunderstanding something ? Hang on This list also misses the 24 f1.4 and the 28 f1.4 - in fact it misses out all the lenses which were always 6 bit coded (WATE 0.95 noctilux, 50 APO, 21 'lux etc. etc) I think it would be safer for Monochrome to look on the info screen and see whether it says 24 f3.8 when the lens is fitted (in automatic mode).

Monochrome Posted April 6, 2016 Author Share #8 Posted April 6, 2016 I did some other tests today. Using the lens with the automatic profile gives the best results, slightly better then with the 24/2.8 asph. profile selected manualy. But it doesn't take the problem away completely. When shooting a grey sky i can still see a magenta cast on the right hand side of the picture with the left side being a little less oblivious. With no profile selected (off) the cast is very clearly visible. I am somewhat surprised by this phenomenon, and never heard about it. My 35/2 Summicron type IV doesn't have it even with the lens profile "off". I wonder if it is a problem with all lenses wider than 35mm? Thanks for all your input so far. If anyone has similar problems or knows a solution i would like to hear about it. Link to post Share on other sites More sharing options...
Peter Kilmister Posted April 6, 2016 Share #9 Posted April 6, 2016 Hi Monochrome, Your English is excellent but the word at the end of the first paragraph probably ought to be 'obvious' rather than 'oblivious'.

graphlex Posted April 6, 2016 Share #12 Posted April 6, 2016 For comparison, I don't see any magenta fringing with the 24 Elmait-M f/2.8 on the M240. Link to post Share on other sites More sharing options...
Monochrome Posted April 7, 2016 Author Share #13 Posted April 7, 2016 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! It is not color fringing but more like a vignetting on the right and left side of the image. this one is taken with no lens correction to show the effect more clearly. F stop was 4.0. I wonder if anyone has similar results with a M (240/262) and a Elmar 24mm/3.8 or any other wide lens. Like i said in earlier posts, the effect is less visible with lenscorrection on automatic, but against a clear sky it is still there. Monochrome.

flyalf Posted April 7, 2016 Share #14 Posted April 7, 2016 Its possible to correct post with Cornerfix. Link to post Share on other sites More sharing options...
Monochrome Posted April 7, 2016 Author Share #15 Posted April 7, 2016 Flyalf, thanks for your reply. I know i can fix this in post (Adobe Lightroom has a similar plug-in), but i find it odd that Leica isn't able to correct this "in-camera". Like Ict said in his reply, the automatic lens correction for the Elmar 24/3.8 isn't able to take the effect away completely. That being said, i am still wondering if the effect is so clearly visible with other M users who have this lens. Also i wonder if it is same with other wide angle lenses? For instance, is it visible with the new 2016 Summicron 28mm or the Elmarit 28mm? Was this effect the reason Leica updated these lenses in the first place? I understand from other forums that it might have something to do with the use of mirrorless camera's and wide angle lenses. Can someone explain this perhaps? thanks, Monochrome.

Schrödinger's cat Posted April 7, 2016 Share #16 Posted April 7, 2016 Try manually testing some of the profiles for other lenses and see if it makes any improvement. Link to post Share on other sites More sharing options...
lct Posted April 8, 2016 Share #17 Posted April 8, 2016 Just shoot a gray monitor with any 21 or 24 folks and you will see more or less color shift out of any full frame M most probably. Link to post Share on other sites More sharing options...
Peter H Posted April 8, 2016 Share #18 Posted April 8, 2016 I can find plenty of vignetting (not obtrusive or unexpected for this fl) but no magenta sides or other casts on my Elmar 24/3.8 on my M240. Link to post Share on other sites More sharing options...

CheshireCat Posted April 8, 2016 Share #20 Posted April 8, 2016 This does seem a bit odd and perhaps not normal for the 24mm SEM. Agreed. Never had any issue with the 24/3.8 EM on M9 nor M240. Note that it is just "EM", because the 24/3.8 is not "Super". Well, it actually is super, but not in the lens name Link to post Share on other sites More sharing options...
