Brian,
I was recently shooting a snow scene with dark rocks, using the setup in the subject line. I have CA on each and every edge of the snow. The 10-22mm is rated pretty good for CA.
Questions I have since I have used this lens for 4-5 years now and have not had as much of an issue as I did last weekend.
1. Is CA strictly caused by the lens or can it also be the camera body and/or camera body+lens combo
2. In the past I was shooting with a T2I with AV F11 or so. Now a 7D Mark II with F16-F22. Does Aperture make a difference?
Any other suggestions to avoid as much CA as possible?
Thank you,
Colleen
