The Nikonos V is the culmination of Nikon's underwater 35mm viewfinder camera system. Introduced in 1984, the Nikonos V enjoyed a production run lasting until 2001. The Nikonos V is the most complex and feature-filled of the non-SLR Nikonos cameras and, as such, it is also one of the most sought after cameras.
While the preceding Nikonos IV-A introduced TTL light metering and an aperture priority mode to the system, the Nikonos V added a full manual exposure, in addition to as aperture priority. Otherwise, the V has a very similar form and control layout to the IV-A. The camera is a viewfinder-only camera, and focusing must be done via distance scale on the lens. The aperture and focus are set via large knobs to either side of the lens, while shutter is set via a familiar shutter speed dial, atop the camera. The viewfinder displays a simple light meter that indicates over, under, or correct exposure.
Most of the Nikonos lenses were marked "UW" and are for underwater use only. However, there are two Nikonos lenses, the 35mm f/2.5 and the 80mm f/4, which can be used both above and below water. On land, the 35mm has a slightly wide angle field of view, while underwater it has a field of view roughly equivalent to 50mm. The same applies to the 80mm, this field of view multiplication is due to diffraction caused by water. Nikon also produced an on-land only LW 28mm f/2.8.

Nikonos V - Don't Fear The Rain
Easily one of our all-time favorite rainy weather cameras: the Nikonos V. We love the feel of this camera, the muffled sound of its shutter, the smooth film advance stroke, and the utter fearlessness it gives us walking around in the Oregon winter weather. If you are in need of a stalwart, rainy-weather companion, this is a camera to track down.
