I'm thinking about getting an EOS M and 22mm f/2 and would be grateful for your views. Was the chromatic aberration turned on for these test shots? There does seem to be some purple fringing along the outer edge, roughly the same as the 35mm f/2 (non-IS version).

Kind regards,


I turned in the in-camera CA reduction off and shot RAW for these tests.

I don't test exhaustively for CA but my gut impression was that the EOS-M does it less than the Sony. (The Sony gets an awful lot of purple fringing, even when stopped down in the corners.) The Canon also seems to have less distortion, which is another pretty cool plus for a compact wide angle!
