Canon TS-E 17mm f/4L

Manufacturer's Description:

"Canon was the first company to offer 35mm camera users a combined tilt and shift lens, With 36 years experience in this field, Canon has now added a new unique functionality to the TS-E 17mm f/4L, allowing users to rotate the direction of the tilt and shift independently of each other. This affords greater control over the focal plane, replicating the movements of a large format view camera. Canon's revolutionary tilt and shift revolving mechanism is particularly useful when shooting product shots from a perspective where specific framing and focal plane is required."
