Well, basically I am looking for something to replace my 18-55 at the 20-80mm range, and from what I've read, these two seem to be pretty good quality lenses at an afforable price compared to what Canon offers in terms of quality (these seem to be in the middle of the standard and L series Canon lenses at these focal lengths)
Basically which is better overall, I will mainly use this lens for portrait work, possibly some landscape at the 28mm end, and also the bit of random nature photography, trees close up, rock formations and other crazy abstract stuff like that.
Thanks
