I'm very interested in this lens as a replacement for my 70-200/VR. Two issues are holding me back though.
- Is it sharp wide open? Some full resolution samples at different focal lengths would be very much appreciated.
- Every shot I've seen with this lens seems to have a bit of a purple/blue tinge to it, especially skin tones. Anyone else notice this? I'm very particular about rendering, so this is a major issue for me.
