When used in automatic mode, it's possible to lock the current aperture value, then recompose the picture, if desired, by pressing the small silver button next to the film rewind knob.Īutomatic exposure required the FD-mount lenses.
#Canon 35mm film camera manual
The Canon EF could operate "Variable Aperture AE" mode (commonly called shutter priority) or full manual mode, where the operator would control both the shutter speed and the aperture. Note that this requires the camera to be held horizontally taking vertically oriented pictures requires some care by the user. The Canon EF contained a silicon photocell light meter with a range of EV 18 to EV -2 which measured light in a "central emphasis metering" pattern (also called center weighted average metering) with less influence from the top of the frame, to minimize underexposure due to a bright skyline. Neither does it provide any interchangeable viewfinder. Unlike the F-1, the EF does not support any motor drive for film transport. The EF shares the F-1's rugged construction and tough metal body. The shutter is mechanical at all speeds starting at 1/2 second and faster, but from 1 second and beyond the shutter is all electric, allowing for AE shutter speeds as long as 30 seconds.
The EF was built as an electro-mechanical version of Canon's top-of-the line wholly mechanical Canon F-1. It was compatible with Canon's FD-mount lenses. The Canon EF is a manual focus 35mm single-lens reflex camera produced by Canon between 19.
