Tilt Shift Photography is very interesting to me, I would love a chance to try out one of those lenses just to help understand it more.

DPReview.com reviews the new Canon 100mm 2.8, how does it stack up against the other versions?

Canon has just published a new version of the Professional Series White Paper. I find these very informative when learning to use the 1 series cameras. They are very detailed and help you understand how to get the most out of the camera.
