This is a Nikkor 35mm f2,8 PC (Perspective Control) lens.

From Ken Rockwells' review of this lens "I can't figure out why people would want a PC lens in 35mm format. It has no tilts or swings.

If you are going to spend the time to get good results you should be shooting a larger format.

If you are doing digital or low-resolution work you can shoot with what you already have and correct it in Photoshop.

Some people do make creative use of the PC lens. I've seen a shot by Galen Rowell from an airplane where he deliberately shifted the lens the "wrong" way to exaggerate perspective. This is cool, but he still had to meter the hard way.

For what you pay for this lens you could buy a used view camera and lens." Sure looks cool though.
