It doesn't appear that Canon does much to help remove or reduce fringing in high-contrast areas of photos. Most megazoom cameras produce a lot of fringing, but some create more at the wide or telephoto positions. The SX40 HS is bad at both ends, to the point where you'll see it in larger prints or if you crop heavily. If you're able to look past it or don't mind removing if it bothers you, then it's a nonissue.
As for lens distortion, Canon keeps the barrel distortion in check at the wide end; there was some on the left side of our review camera, but it's barely detectable. When fully extended, the lens exhibits slight pincushioning, but not enough to be concerned. Center sharpness is good and the lens softens only a bit out to the sides and corners.
