I recently bought a 20D with the 17-85mm EFS lens and, though I'm very impressed with the camera, I have had horrible problems with chromatic aberration with this lens.
There are thick magenta or blue bands at the edges of the image (high contrast borders), particularly at the wide angle end.
I have had the lens replaced by the supplier and the same poor quality was evident with the 2nd lens.
I have now opted to change for the 17-40mm f4L as I have no faith in these new EFS lenses.
This is my first experience with Canon as I have used Contax/Zeiss T* for the last 20 years. I was astonished that Canon could put out such c**p at a supposedly high end level (£470 is not a cheap lens).
I assume the EFS lenses do not use low dispersion glass, they obviously need it.
Has anyone else experienced this problem?
Matt.
P.S. I've also just got a 70-200mm f2.8 IS and that is an absolute beauty, I can highly recommend it (maybe Canon reprieved themselves a bit with that one).
