I don\'t think any lense should look that way at all. If it is possible, attempt to use this lens on another body to rule out your camera. I would suggest ISO 200 or so just to minimize the sensor blooming. If the problem persists, you definitely need your lens looked at. If it is in warranty, show Canon your unedited RAW file so they can see it for themselves. The camera comes in a relatively hefty price so one expects quality, surely better than a regular consumer camera.
Also, try going to a camera store with your body and use the exact same model lens and take a shot of another contrasty subject matter. See if this is consistent. Then use another model lense, such as the 24-105L set at 85mm with similar settings as this sample shot and see if the problem persists.
Just so you know, I\'ve seen too many lenses out of the factory that need to be calibrated.
Good luck!
P.S. The only time I ever resorted to PS lens correction for CA was the last time. The lens needed fixing and that was that. PS is great, but I try to get as clean an image at capture to reduce post-production.
Nope. My EF100/2 did the same thing...it\'s a common issue with fast lenses and isn\'t an issue with the copy of the lens. Go to www.photozone.de and look at the reviews for this lens (and other fast lenses). You\'ll see that purple fringing is a common issue.
