tnturnerx1 Posted January 1, 2012 Share #1 Â Posted January 1, 2012 Advertisement (gone after registration) I've only had my X1 2 months, but have been practising with it a lot. Normal (whatever that is) images do not exhibit chromatic aberration, but on occasions, a very noticeable fringe shows up at the edge of some objects--not all objects in the image, but usually when the object is backlit with good natural light. I'm surprised at a lens of this supposed quality behaving this way. Also, in ACR, there is no lens correction for this particular lens, and the closest I can come only reduces the aberration a little bit such that the image is still unacceptable. Anyone notice this?

tnturnerx1 Posted January 1, 2012 Author Share #2  Posted January 1, 2012 PS: I forgot to add one of the photos that exhibit this behavior. Also, for some reason this post is related to a different post I replied to, so I must have done something wrong with the post. Upper right area, particularly right side of tree trunk. Don't know if you can see it on this drastically reduced size. thanks Welcome, dear visitor!

nickma Posted January 1, 2012 Share #3 Â Posted January 1, 2012 For what its worth I find shots taken with the X1 in similar conditions and from the exact same spot with my old Canon 40D with a decent lens such as Canon's 10-22mm USM or the old 24mm fixed prime exhibit **much less** purple fringing on fine branches against white or bright sky. Yes sometimes I get a little on some shots, but producing way better results than a decent pro-am SLR with good optics from a little pocketable camera seems like a pretty decent outcome.

Mr_Jones Posted January 2, 2012 Share #4 Â Posted January 2, 2012 I went through the process of creating a lens profile for my X1, you just need to print some chequered patterns and photograph them. I did put some examples up in a thread here. I feel it's worth doing and use it all the time. Â On the other hand some forum members believe that Leica would already be adjusting for the properties of the lens in-camera as it is a fixed lens this would make sense.

Ivan Muller Posted January 3, 2012 Share #5 Â Posted January 3, 2012 Looks pretty bad to me.....what raw converter are you using? In fact your sky varies between pink/magenta to blue /cyan...... Link to post Share on other sites More sharing options...
tnturnerx1 Posted January 8, 2012 Author Share #6 Â Posted January 8, 2012 Since I made this post, I "googled" it, and found many posts on various photo sites about similare chromatic aberration. In such cases, I simply have to toss the image as there is no good fix for it. Link to post Share on other sites More sharing options...

phancj Posted January 11, 2012 Share #8 Â Posted January 11, 2012 I believe the jpeg conversion in camera will take care of this, but not in Raw. Â LR3 does help tremendously. Toy with the sliders. Â I have seen this problem, but not to this extent and probably a few shots out of the couple tens of thousands of shots. Â CJ Link to post Share on other sites More sharing options...

phancj Posted January 12, 2012 Share #10 Â Posted January 12, 2012 My guess only nothing concrete is that leica refuses to share their image processing parameters with adobe. With nikon you can see an integration in LR with multiple possible presets plus lens correction profiles already there in LR. Â CJ Link to post Share on other sites More sharing options...

phancj Posted January 16, 2012 Share #12 Â Posted January 16, 2012 personally I recommend setting to "embedded" instead of "adobe standard". Almost always (notice always) the embedded looks more right to me, so I guess "adobe standard" is adobe's interpretation of the file? Â I recommend using LR3. Otherwise just use the jpegs which are very good already. Â FWIW my brother owns the x100, I compared files shot same location and angles the X1 jpegs are better, raw there is very very little to tell the files apart.

Nevin Nevin Posted January 16, 2012 Share #13 Â Posted January 16, 2012 Could the purple fringing (you mean top left in the shot?) be related to the shorter flange distance? The shot was done in f4.0. Maybe closing down the aperture can avoid this fringing behaviour a bit? Being new to the Leica X1, I can make the wrong guess and miss the point though.
