70-200mm f/2.8L IS II chromatic aberration

[Mt Spokane Photography]

Its purple fringing. Most lenses have it at wide apertures where there are sudden light to dark transitions, and the 70-200mm L MK II is no exception.

If you use lr4, you can pretty well remove it, however, as a side effect, it removes the purple from the entire image, so the skin tones were affected. They can be fixed, but I did not want to spend the time.

So this amount of color fringing is perfectly normal?

This is unedited, earlier on the same day.

and where do I find the DLO or CA module in DPP?

DPP does not do a good job of removing purple fringing, its reduced a bit, and triples the size of your file. Other software cannot read the alterations in the cr2 file, so you must save it as tiff or jpeg to see the changes. Its not a very easy solution compared to lightroom.

I also have occasional CA problems with this lens. I try to cure it in RAW. In RAW I can control intensity and luminance of purple. This way it gets less visible.

I used B+W MRC haze filter... do you guys think that might be the problem? :/

and I always thought chromatic aberration and color fringing were the same thing? How can you tell color fringing from chromatic aberration?

My understanding is that purple fringing is a type of CA so I think in your case they are the same. I am surprised at the amount being produced by your copy, have you had the lens for long? I have the same lens and it's perfect, I have yet to notice it but I don't think i have photographed such extreme transitions yet between white/dark but I have photographed tree leaves and such against the sky and typically those will show CA as well. Try again without your filter, if it's your copy you can try having Canon take a look as I'm sure it would be a warranty item or just remove in PP.

avatar13: I've had the lens since January. Yesterday I did some graduation pictures and again the color fringing is thick. I forgot to remove the filter! Next time I'll try it out without the filter.
