Introduction
The Canon Scoopic 16-M is a high quality 16mm cine camera designed for
professional and advanced amateur use. It is designed to meet the current market
demands for high quality, versatility and ease of operation in a compact package.
It provides all the features of the original Scoopic 16 such as built-in zoom
lens, automatic exposure control (EE), automatic film threading, 100 ft. film
load, and "human engineering" body and grip shape. New features of the Scoopic
16-M are provision for single frame photography, macro focusing lens, and
the adoption of the true transmis sion "T" number marking system for the aperture
rather than the theoretical "F" number marking.
The camera has also been designed for easy maintanence. Most adjustments
can be made from the outside without major stripdown.
