I am quite happy with the image from this lens as long as I shoot at f5.6 or above.
Oh, I think I set the Sharpness to +1 and the rest I just cut and save and post. no other post processing.
I think it is pretty darn good for the kit lens.
CA is very minimal.
This lens is so light, I am happy to bring it everywhere.. still won't replace my 28-135 or 24-135, but for the range (27-105 equiv), it is good.
