300:. Unusually long exposures (from 1 second to 30 seconds) were electronically controlled, while shorter ones (1/1000 second to ½ second) were mechanically controlled. This was very useful in conserving battery power, and allowed one to use the camera even with dead batteries. The light metering system's power switch turned on the meter, removed the lock from the shutter trigger button and let the film advance lever pop out 15 degrees from the camera body, all in one flick of the thumb. In the axis of the main switch, a multiple exposure button is located. Pressing this while cocking the shutter prevents advancing the film. The frame counter is also blocked, thus preserving the correct frame count. At the time, most cameras did not support longer exposure times than about one second, without having to use the bulb setting. Maybe this was why Canon placed a red LED to the left of the pentaprism, and had the LED flashing as long as the electronic shutter timer was running. The LED was also used for battery check. 308: 199:. The shutter is mechanical at all speeds ½ second and faster, but at 1 second and longer the shutter is all electronically controlled, allowing AE exposures from 1/1000 to 30 seconds. The EF shares the F-1's rugged construction and tough metal body. Unlike the F-1, the EF does not support any motor drive for film transport.

1:5.6 S.C. The smallest aperture is not adjusted for. The camera always displays apertures up to f/22, but with a red line down to f/16, to remind the user that some lenses, like the Canon FD 50 mm 1:1.4 S.S.C. has its smallest aperture at f/16, while some, like the Canon FD 135 mm 1:2.5 S.C. can stop down to f/22.

The EF is the only camera in the manual focus Canon line of the 1960s and 1970s (which includes the FTb, the F-1, and the FT) that can be used with common 1.5 volt batteries without modification to the internal electronics. 352:

The film advance lever, though it stands out from the body when the shutter lock button is released, has a soft spring that allows the lever to be pressed back in to the body during use, without turning off the meter, and therefore does not hinder left-eye users shooting in landscape format.
