Any of you have this lens? I am giving it serious thought. I take a lot of pictures that I post on our online store. I am always trying to get a better shot. Right now I use a 100mm macro by Canon, it is a very nice lens, but it is fixed (no zoom) so I am considering this other lens as it has a very wied angle on it. 17 * 1.6 = 27.2. This is an f2.8 lens as well. The only drawback is the price, it is about $1100.
