I figured I couldnt go wrong with either but with the plastic body of the XTi, it wouldnt exactly be balanced or comfortable around my neck with a few lbs. hanging off the front.
I know with my macro lens, it makes the camera VERY front heavy but thats fine because its almost always used on a tripod. With the type of lens Im looking for now, I think the 17-55 is my best bet. Plus its a few bucks cheaper than the 24-70 so my wallet will thank me.
Thanks for the help guys. I will post some pics in a few days when I pickup the 17-55.
Happy Holidays!
