Nikon PC-E Micro NIKKOR 45mm f/2.8D Perspective Control Lens
Along with catadioptric (mirror) lenses, I’ve always been intrigued with the “perspective control” lens, also known as a “tilt and shift” lens. It’s the SLR’s take on the view camera, bringing some of its functionality to the smaller 135 format. One of its many uses is to correct the rather odd perspective when photographing tall buildings or other objects from a low angle. It’s what separates the pros from the amateurs in dedicated architectural photography.
