The Krasnogorsk-3 (Красногорск-3) is a spring-wound 16mm mirror-reflex movie camera designed and manufactured in the USSR by KMZ.
[1] It was one of the most popular 16mm movie cameras in Eastern Europe, where it made a prominent appearance in Krzysztof Kieślowski's 1979 film Camera Buff, and continues to enjoy considerable popularity in the West.
Cameras which have been modified from the original standard 16mm (double-perforartion) to accept Super 16 (single-perforation) film may experience vignetting at the widest zoom setting with stock Meteor lenses.
Film speed is adjustable from 8 frame/s to 48 frame/s; however, many cameras are capable of functioning at higher frame rates (upwards of 60 fps) if the adjusting dial is turned beyond the 48 fps indicating mark.
The PX640 battery required to power the internal light meter is no longer sold due to its mercury content.
