I just bought a used Tokina 80-200 f2.8 and have noticed some purple fringing in my test snaps.
I don't know if this is normal or if its severe and I should send the lens back, or if its mild and acceptable.
What causes this, and are there some situations that this would be a real image killer?
I'm thinking this is mild, but I haven't had this problem before.
These are jpegs with camera processing turned to minimum and no post processing.
Thanks,
Mark.

I think you need to send it back and get another one personally.

What aperture was this shot at?

What aperture was this shot at?

Both at f 4. heres one at f16 straight from camera and with auto levels. looks to have purple cast.
Would like suggestions as to how to check this out further if need be,
Thanks,
Mark.

An overall color cast has to do with the white balance - I don't think this is a fault of the lens although some people used to say that they could see some lenses were a little "warmer" than others when shooting slide film.

I don't think the color fringing is that bad. Your example is a real tough test because you'll see it mostly where you have a light area right next to a dark area. Doesn't get much more pronounced than this example! F4 should look better than wide open, but F5.6 might be better yet. Personally, if it was my lens I wouldn't be too worried about it.

Thanks Peter, thats exactly what I thought yesterday when I saw these. even though these two pics were the only ones out of a handfull that showed the problem(a high percentage).I have checked it against another lens and it does a better job. And I do hate returning things!

Thanks for the help. I was hoping for some reassurance. Sharpness and contrast are nice. It seems to work well overall.
