I use this lens on a Canon Rebel xti. I recommend getting it from B&H or Amazon.reviewed July 11th, 2008 (purchased for $585)
It's a large lens, yes, but smaller than other f/2.8 lenses of with similar range. It is even small enough to fit in my little Lowpro Slingshot AW200 Bag while still attached to the camera.
This lens is a lot of fun to use! It's like having a telescope and a microscope attached to your camera at the same time.
Great for use indoors (low light) and outdoors. This is good to shoot, portraits, family moments across the room, or maybe a wedding. It's not just for bugs and flowers. However it is really good at bugs and flowers, and they are surprisingly fun to shoot.
For image quality.. the test results above speak for themselves.
It is a bit of a challenge for a newbie to place the narrow depth of field at f/2.8 correctly all the time, but its a fun and rewarding challenge.
The motor is fast, and very quiet, however this is a macro lens so fast is a relative term here. The focus ring must rotate a full 270 degrees to move the focus from 1:1 macro all the way to infinity, so it takes a bit more time than you may be used to on non-macro lenses.
I like the build, it feels like this lens will be sturdy enough to be a longterm investment. It's kind of expensive, but that is also relative... it is a great price, comparatively, for a lens of this quality.
