Canon EF 24-105mm f/4L IS USM Lens

This is probably one of my favorite lens and gets used most of the time. This "L" lens is sharp and colors turn out wonderful. More rich color than non-L lens. Weight is surprisingly light considering it's got IS(Image Stablizer) mechanism. Speaking of IS, this works like a charm and f/4 isn't much of a problem at all and if you mate it with Canon digital EOS cameras such as Rebel XT, 30D, 5D, 1Ds, it produces some amazing shots. I've used 28-135mm IS, and EFS 17-85mm previously and can tell you that the shots are kind of soft. Maybe that's why they are only 1/3 of the price of 24-105mm lens. I recommend it to anyone who wants best image quality, well built, great range lens.
