Lenses with 'shift' capability have been available for 35mm and medium-format SLRs for decades. What made Canon’s Tilt-Shift lenses special was summed up in their name. For the first time, SLR users had a lens that could mimic the movements of the front standard of a view camera. These lenses not only could shift to retain proper perspective control, but also could tilt to alter the plane of focus.
Now more new Tilt-Shift prototype lenses have been spotted in field tests. The older 45mm and 90mm lens are long overdue to be upgraded and become 'L' grade so there is a chance they may be announced before the end of the year and available for early 2014.
