Nikkor 50mm 1.8 Nikon 3214543 - none AI
The 50mm F/1.8 lens, or the “nifty fifty” as photographers lovingly call it, has long been known as the best possible bang for buck. On a full frame sensor or 35mm film, the 50mm focal length has been the “standard” for years.  It was the brainchild of Mr. Souichi Nakamura, Nikon’s most celebrated lens designer and the creator of many Nikon optical designs.  Manufactured in Japan from July 1981 - September 1985.  Similar lens have sold on eBay from $75.00 - $90.00.

RMC Tokina Doubler
The Tokina 2x RMC teleconverter is mounted between the lens and the camera. The teleconverter doubles the focal length of the existing lens and minimizes the relative aperture setting on the lens by two f-stops; therefore, quadrupling the exposure time. With this converter focusing is virtually unaffected and the focal scale can be set to infinity. The 2x Tokina is compatible with Nikon F mount AI lenses.  Has sold on eBay for $15.00
