In 2005 2,500 models of a repro model were manufactured under the name of "Nikon SP Limited Edition". The camera was exclusively sold in Japan and came with a (modern multi-coated) W-Nikkor 3.5 cm f/1.8 lens.

Features

The Nikon SP has dual viewfinders providing frame lines for a total of six focal lengths. The main viewfinder has 1x magnification and has frame lines for 50mm, 85mm, 105mm and 135mm (selected by rotating a dial under the rewind crank). The frames are parallax-corrected and the focusing patch appears in the centre of the viewfinder. A separate, smaller viewfinder (less than life size) to the left of the main viewfinder has non-parallax corrected frame lines for 35mm. The entire window acts as a frame for 28mm lenses.

The camera uses Nikon's 'S' bayonet lens mount

 which is a modified Contax 'C' bayonet and Contax 'C' lenses are physically compatible but do not accurately focus with the built-in rangefinder. In common with Contax, a small toothed wheel in front of the shutter release is used to focus lenses that use the internal bayonet.

The camera does not have a flash sync on its hot shoe
Hot shoe
A hot shoe is a mounting point on the top of a camera to attach a flash unit.- Design :The hot shoe is shaped somewhat like an inverted, squared-off "U" of metal. The matching adapter on the bottom of the flash unit slides in from the back of the camera and is sometimes secured by a clamping screw...

Pentaprism
A pentaprism is a five-sided reflecting prism used to deviate a beam of light by 90°. The beam reflects inside the prism twice, allowing the transmission of an image through a right angle without inverting it as an ordinary right-angle prism or mirror would.The reflections inside the prism are not...
