Canon F-1

This represents a turning point for Canon: their first professional grade camera, introduced in March of 1971 along with a new lens mount – the FD range.

The F-1 established it’s pro-credentials by offering a huge range of interchangeable parts – viewfinders, focusing screens, winders, backs – and a range of flash accessories. Also notable was the 1/2000s top shutter speed

A number of interesting technical solutions are seen with the F-1, including TTL metering achieved by locating the meter cell at the side of the focusing screen, where light was directed to it by a small mirror. This allowed metering to be independent of the finder attached, much simplifying things.

One of the most curious accessories was the Servo EE finder, a bulky finder made even bulkier by the battery pack it needed, holding 8 AA cells. This finder incorporated a servo motor – hence the name and the need for all the batteries – which mechanically connected to the shutter speed dial in order to change speed based on metered light and selected aperture.
