Aside from the miniature HIT camera, the Diana is the lightest camera in my collection. Manufactured by the Great Wall Plastic Company on the 1960’s as a very inexpensive novelty camera (and copied extensively). This is the original “No. 151 Made in Hong Kong” model which, as I understand, produces interesting results from its plastic meniscus lens.
It has a two-speed shutter (B and I) and three aperture settings, Sunny, Partly Cloudy, and Cloudy which roughly translate to f22,f16, and f11 respectively) and three-zone focus which in the absence of positive lock is essentially 4ft to infinity.
