This lens was added to our arsenal about a week before Christmas of 2008 and wasn't in our possession all that long because it was replaced by the 16-35mm f/2.8 MK II from Canon.

While this lens is intended to be used on Canon's 1.6 crop body cameras, I have used it on both the 1D MK II and MK III camera bodies and gotten some very nice results.

The shot of the Xcel energy center was when it was mounted on the MK II camera.
