Review on Canon TS-E 17mm f/4L UD Aspherical: The Ultimate Tilt-Shift Lens for Canon DSLRs by Joshua Sharma

PRO: This lens is essential for architecture or interior design. Even if you have to buy a Canon full-frame body to take full advantage of it because you're using a different system, just consider this lens and camera a must-have purchase. The TS-E 24mm, a great lens, often lacks that little bit extra to frame the shot perfectly. The TS-E 17mm gives that extra something that gets it right. CONS: I don't have enough filters to protect the front surface of the lens. Just pay attention to what you're doing.
