sandymc Posted July 7, 2013 Share #21 Posted July 7, 2013 Advertisement (gone after registration) A Cornerfix Aperture plug-in would be very helpful. Regrettably Apple don't make the required "hooks" available to third parties. Although one of the Apple folks once told me that Aperture is actually designed to accommodate such things.

Sandy But there are plugins- so assume developers do make them and that they hook in properly? Link to post Share on other sites More sharing options...

satureyes Posted July 7, 2013 Author Share #25 Posted July 7, 2013 ok so.. first trip out with the new M.. Loving it all - but I'm totally shocked at the purple band along the edge of the frame in my 21mm Super Elmar shots.. Earlier I saw it happening massively on the Voigtlander 12mm but I put this down to the non-Leica lens and how wide it is.. but looking at almost all my new M images with the 21SE there's a magenta band along the edge of shot.. as well as some pretty annoying vignetting. Shame - these were not there on the M9 - and I know firmware etc etc.. and corner fix etc etc but surely for a New(isn) released Leica lens this shouldn't be an issue on the new M? See what I mean.. here.. http://500px.com/photo/39753670 Link to post Share on other sites More sharing options...
BerndReini Posted July 7, 2013 Share #26 Posted July 7, 2013 I know that most camera manufacturers integrate some kind of firmware correction for lens shortcomings into their cameras. I'm sure the RX1 does it and I certainly know that Panasonic does it for their 20mm 1.7 for example. The unfortunate side effect of all this is that you are already pushing your files around, which ultimately degrades image quality. The "cleaner" the file that comes out of the camera, the more latitude you have for post-production. Link to post Share on other sites More sharing options...
jaapv Posted July 7, 2013 Share #27 Posted July 7, 2013 Advertisement (gone after registration) Purple fringing: The higher the edge contrast of the lens and sensor, the more you will see it. Nasty, but a fact of digital life, reason why raw converters have "defringe" sliders. I just noticed the same on the Summilux 24 on the M. Link to post Share on other sites More sharing options...

helged Posted July 7, 2013 Share #31 Posted July 7, 2013 Yes, at least on my M240-21SE combo. Mis-coloring is also seen at the lower third of the short-side edges of the OPs photo. Link to post Share on other sites More sharing options...

Lightwrangler Posted July 7, 2013 Share #33 Posted July 7, 2013 What a stupid conversation. What we see here is not Purple Fringing, but color shifts due to the use of wide angle lenses, a problem Leica made us believe is obsolete with the new M. But it obviously is not. Corner fix seems not to be out of business yet. Mike Link to post Share on other sites More sharing options...
satureyes Posted July 7, 2013 Author Share #34 Posted July 7, 2013 ok -that photo perhaps wasn't the best example.. but I am also not a techie - just a photographer! Here's an original straight out of camera - with just default RAW decoding in Aperture. on the right - there's a definite line of magenta. Also that lovely new Leica 'dust spot' feature.. which comes free with all new cameras http://www.satureyes.com/img/s10/v115/p1613536584-6.jpg Which doesn't look that bad on my iPad but does on my calibrated monitor. Hmm... Link to post Share on other sites More sharing options...

kokoshawnuff Posted July 8, 2013 Share #36 Posted July 8, 2013 I had the opportunity to try an M with my SEM 21, unfortunately the camera was manually coded to a summicron 50 for some reason, so I can't really give a valued opinion other than the photos I took only showed minor vignetting at the corners...here's a rather barren shot from LR4 to highlight issues Link to post Share on other sites More sharing options...
CheshireCat Posted July 8, 2013 Share #37 Posted July 8, 2013 Thanks for that explanation- really helped. I've had people tell me my camera is faulty. Clearly not true. Well, let's say all M 240 are faulty by design. Indeed, it is not user error, and knowing that all M 240 users have this issue is not going to make it any better. What CornerFix does could be easily implemented in-camera (just allowing custom profiles), but this kind of processing is science-fiction for Leica.

Guest snowboarder Posted July 8, 2013 Share #38 Posted July 8, 2013 This is a joke. Leica M camera supposed to work well with Leica M lenses. If not, what's the point? NEX-6 seems to work better with those wide M lenses... Seriously, is there anything good about this camera? Sensor s@cks, electronics s@ck, everything else is a joke. What an accomplishment! BTW 21SE is a brilliant lens... Link to post Share on other sites More sharing options...
IkarusJohn Posted July 8, 2013 Share #39 Posted July 8, 2013 Hi Rick, I don't have a calibrated screen (an apparently crappy Apple Cinema screen) and the purple down the left side of your first image and down the right of the second is plain as day, and very unattractive. It might be more accurate to call it Italian Flag rather than purple fringing, which is chromatic aberration (he says, waiting to get shot down in flames). Was the lens coded correctly? Presumably this can be fixed with a firmware update (he says hopefully) ... Disappointing. Cheers John Link to post Share on other sites More sharing options...
BerndReini Posted July 8, 2013 Share #40 Posted July 8, 2013 I would happily suffer a drop in resolution to end time in editing. I have 20+ megapixels to play with. Happy for a few to go towards image correction. I agree with you, which is one of the reasons I'm holding off on the M240 (white balance not corners). What I'm saying though is that I wish Leica had implemented a better hardware solution with the new sensor rather than something that seems to be a step backward from the micro lenses. Also, I'm not talking about resolution, but when you start "pushing" around colors and increasing exposure in the corners of files from wide lenses, the resulting file will still have full resolution but won't be as "clean" at the edges.
