After reading many 35L topics on FM, I decided this lens could be for me. I bought it new about 9 months ago and I've loved it ever since.
Still, I feel it has lots of Chromatic Abberations, or purple fringing. I knew that this was one of its flaws, and it only bothers me in high contrast shots in the 1.4-2.8 range. But that range is what I shoot most, so I was wondering if my copy delivers about standard quality, or if it is substandard.
I'd like to show you some images, but I'd like some suggestions about a test setup: which subject, what light to use?
Most all lenses can produce at least some purple fringing in very high contrast areas near the edge of the frame, especially if the light areas are blown out.
Why don't you post one of the existing images that leads you to think you have a problem?
Your lens looks typical to me. Very high contrast will make fast aperture lenses like these show aberration. Shiny objects against a black background (the lens cap test) are one of the worst-case scenarios.
With fast prime lenses you get red/purple fringing in front of the focus plane and green behind it. So when you are not exactly on the focal plane you may see those colors appear, even in the out of focus areas of the image.
Your images look fine for high contrast subjects though. Stop down to eliminate it under stressful conditions optically if you need to get rid of it.
Looked at your examples, and I don't think you have anything out of the ordinary. In each case, the purple fringe is next to a pure white (or badly blown out, as in the case of the reflective can) area. In those shots I would chalk it up mostly to a need to make a different exposure choice. Even in the images of the reddish flat surface with the torn edge, the white areas of the torn edge - which show a tiny among of fringe perhaps - are very bright and perhaps slightly blown. (Do they flash the "blinkies" in your LCD or do they "peak" in your post-processing software?)
In other cases, you have issues with blur associated with narrow DOF and in at least one the color is not so much fringing as it is an OOF reflection from a background area that has that color.
Invertalon perhaps is saying the same thing in fewer words.
