Rating : - Great Lens
The lens is a good value. I like the photos that I took with it. It is not too large to carry in a standard bag, but you DO need a shorter lens with you. This is too powerful for many routine shots. It is not quite to the "must have tripod" power, but it is nice to use one if you have the capability to lug one along.
