Northlight Images have posted a comprehensive review of Canon’s 24mm tilt/shift lens, which allows a limited set of view camera-like movements for perspective and focus manipulation:
Keith recently obtained a Canon TS-E 24mm 3.5L lens primarily for interior and exterior photography of buildings. There are quite a few reviews of the TS-E 24mm on the web, but we wanted to give a bit more of a feel for what it is actually like to use a shift lens for real (on a Canon EOS 1Ds). Given the very wide angle pictures you can get with a 16mm lens and the ease of correcting perspective in Photoshop, why bother with this manual focus lens and all the extra effort involved in using it? This review/article is intended to give an overview of some of the effects, and has links to more detailed technical info at the end.
