Tilt/shift photography (the real kind, not the kind you fake with a computer) can be quite fascinating and is a key component of high quality architectual photography. I have often wondered why Canon’s tilt/shift lenses didn’t come in wider focal lengths than 24mm. Tuesday, Canon announced the TS-E 17mm f/4L lens. This lens promises to make high quality wide angle tilt/shift photography available to APS-C sensor cameras (27.2mm equiv) while allowing full frame and 35mm film users to explore a whole new world of creative possibilities. If it is anything like Canon’s other TS-E lenses I’m sure (to the right people) it will be worth every penny of the $2,500 Canon is asking for it. Scheduled to ship in May.
