ArtZ Posted October 19, 2009 Share #21 Posted October 19, 2009 Advertisement (gone after registration) An example with a WATE at 18mm and the red shift - on both edges! - can be seen here: http://www.l-camera-forum.com/leica-forum/forum-zur-leica-m8/98843-problem-mit-dem-super-elmar-18mm.html#post1040557 Danke, Uli. Aïe! Aïe! Aïe! For me, personally, the greatest interest of the M9 is the possibility of using lenses like the WATE as real wide angle lenses. I decided no to be an early adopter of the M9. I think I will have to wait longer than I thought... Link to post Share on other sites More sharing options...

I didn't pay attention to the bottom of the picture where is written "M8 WATE 18mm" Thanks Ario. So, I repeat my question: Does the magenta left edge happen also with the WATE at 16mm and 18mm? Or only with the Elmar 18/3.8 and the ZM 18/4? Thanks Link to post Share on other sites More sharing options...

I have this problem only inside with Tungsten (Kunstlicht). No problems outside and with original Leica Filter. regard philipp Link to post Share on other sites More sharing options...
sandymc Posted October 19, 2009 Share #25 Posted October 19, 2009 Since Mark and Sandy have both showed up (relative experts on edge drift and image flow characteristics) - I wonder if the red/left issue has to do with the sensor being read out in 2 halves and the corrections somehow being applied differentially on each side for that reason? (separate A/D converters?)) I would say unlikely. But all the other explanations I can think of are unlikely as well(!) Sandy Link to post Share on other sites More sharing options...
sandymc Posted October 19, 2009 Share #26 Posted October 19, 2009 Oh... Sandy?... I think I know the answer but with Cornerfix - If Leica comes out with a revised firmware one should shoot create new profiles correct?... Depends on what they change. But I would guess that if you generated a profile from a coded lens, then yes, you'd have to reshoot. If it was generated from an uncoded lens, then probably not.

sandymc Posted October 19, 2009 Share #27 Posted October 19, 2009 Advertisement (gone after registration) I think it's the quick-setting glue Kodak uses. Dries on one side quicker than the other, creating stresses that raise one end of the cover-glass or microlens sheet higher than the other during the production process. Well, you joke, but one explanation for this is that the microlens array is significantly offset from the center of the sensor, or is at an angle to the sensor plane. Which would be a Kodak problem. I find that a bit hard to believe though, the microlens array would have to be way off. Sandy Link to post Share on other sites More sharing options...
erlingmm Posted October 19, 2009 Author Share #28 Posted October 19, 2009 why did you use such a narrow aperture:confused:any lens that wide has gobs of DOF & no lens is at its best so stopped down, particularly ultrawides lovely place & sweet colors, though the red problem to the right detracts What aperture do you use on a sunny day in snowy mountains? This is not low light photography! Besides, I was not aware of the red shift, so no reason to hold back (if it is aperture-dependent). I do have more images from the same series, where there is no red shift, at least to my eyes, I can possibly post later. Back in civilization now, so further testing in similar conditions has to be postponed until later in winter. Link to post Share on other sites More sharing options...
ho_co Posted October 19, 2009 Share #29 Posted October 19, 2009 What aperture do you use on a sunny day in snowy mountains? This is not low light photography! Erling-- I think Art is referring to the fact that most M lenses are apparently at their best nearer full aperture. Erwin Puts has said that on the M8, later designs tend to deteriorate from f/5.6 forward, as I recall. I assume that would hold also for the M9. Andy Piper also ran a series of comparisons where he found noticeable diffraction on the M8 after f/5.6. BTW-- Really lovely shots and beautiful scenery, the likes of which we don't get in Texas.
