This sale is for a Nikon APO-NIKKOR 360mm f/9 process lens.
Nikon's entire series of process lenses are excellent for ultra large format cameras.
Tack-sharp optics. This lens has no optical defects and covers the 11 x 14 format.
This lens comes as shown in the photos: no retaining ring, no lens caps.
Like all process/barrel lenses, this has no shutter. For the long exposures used on an ULF camera, a shutter is really not needed.
The lens board fits Wisner Classic
