Canon EF 35mm SLR, The Black Beauty

Canon EF 35mm SLR, The Black Beauty

Introduction and Overview

Canon introduced the professional level F-1 system camera and the FD range of lenses in 1972 which went on the be a very successful product.

Canon EF, Front
The cost of the system was quite prohibitive for the enthusiast and towards this end, Canon took the cue and launched the consumer level Canon EF, an electronic version of the F-1.

Unique to the EF was the Copal Square shutter, designed to be controlled electronically for shutter speeds from 30 to 1 second, and mechanically from 1/2 to 1/1000 second. The electronic part of the shutter would not be used unless the shutter speed setting was 1 second or longer, which when used with a dead battery, we hardly need never to use these speeds.

Like the F-1, the EF is only available in black, the preferred color for professional photographers, and in addition to the new shutter and autoexposure system, the EF was loaded with many other useful features. In Canon's lineup the EF was placed below the F-1, but above the FTb. The EF was a single model that was the first and the last of the pedigree, was in production for a just over 4 years, making it one of Canon’s shorter-lived models.

Canon EF 35mm SLR

The Canon EF is an Aperture-Priority AE (Automatic Exposure) 35mm film SLR with a Copal Square Electro-Mechanical focal plane shutter, with metal blades running vertically. Shutter speeds available are electronically controlled for long exposures, from 30 to 1/2 second, and mechanical from 1 to 1/1000th second.

The focusing screen is center spot microprism surrounded by plain ground glass ring, and ground glass with Fresnel screen with 92% vertical and 93% horizontal field of view. Film ASA setting is from ASA 12 to ASA 3200. Metering is switchable with an On/Off lever.

The EF also featured a self-timer and a stop-down metering mode which could also be used for depth-of-field preview, and stop-down metering for older FL lenses. The mirror can be locked up for long exposures. Body weight is 740 grams.

Basic Camera Features

This camera is also known as the Black Beauty, based on its gorgeous design out of pure metal with strong and proportional lines.

Aside from the lens mount housing, the front of the EF is plain aside from the Self-Timer/Stopped Down Metering/Mirror Lockup combination mechanism. This multifunction mechanism, with levers both top and bottom, may need a bit of practice to understand its functions fully.

Canon EF, Top

On the left of the pentaprism housing of the top plate is the Film Rewind Crank, which is integrated with the film ISO Selector dial. In between the rewind dial and the pentaprism, towards the front, is the Battery Check LED, and towards the back of the top plate, the AE Lock button.

On the right is the Shutter Speed dial, Film Advance Crank, and Shutter Release button integrated on a single axis, beside which is the Film Counter window.

Canon EF, Back

On the right of the back portion of the top plate is the On/Off Switch which will activate the exposure meter. Switching the lever On will also release the Film Advance Crank from its lock position. On the axis of the switch is the Multiple Exposure button. The film back is hinge type.
Canon EF, Bottom

On the bottom plate of the EF are located the twin-pot Battery Chamber, with a red Battery Check switch on its side, the Tripod Socket, and towards the left of the plate, the Film Rewind Release button.

Canon EF, Film box

The film box is a typical easy load type with a slotted take-up spool. Film loading on the EF was designed without Canon's QL (Quick Load) mechanism.

Viewfinder Readout

Canon EF, Viewfinder Info

The viewfinder displays a horizontal Shutter Speed Scale at the bottom of the screen with an indicator showing the speed setting, and a vertical Aperture Scale on the right side of the screen with a meter needle pointer showing the aperture setting. Red over- and underexposure warning marks are at either end of the scale.

Center-Weighted Average Metering

Canon EF Metering Pattern
Canon EF Metering Pattern
The Canon EF utilizes a center-weighted average metering system which is specially configured to be less influenced by the area at the top of the frame. This is to minimize underexposure which may be caused by a bright skyline. The system is powered by a silicon photocell light meter with a range of EV 18 to EV -2. For a proper meter reading, the recommendation is for the camera to be held horizontal.

The Canon EF can operate in shutter priority or in full manual mode with FD-mount lenses. In automatic mode, the exposure value can be locked with the button, located on the top plate of the camera, between the pentaprism and the film ISO selector dial.

Aperture Priority AE (Automatic Exposure) Mode

This is the recommended shooting mode for the camera (defined by Canon as Variable Aperture AE shooting mode in the camera's Instruction Manual), which varies the aperture opening of the lens based on the shutter speed you select. Set the lens aperture ring to its auto mark, adjust the shutter speed to the aperture that you want, displayed on the right vertical bar in the viewfinder, focus, and release the shutter.

The Canon EF can also be operated in shutter priority or in full manual mode with FD-mount lenses. In full manual exposure mode, you need to first release the auto setting of the lens, set the aperture manually, focus, and adjust the shutter speed so that the aperture needle matches the aperture setting on the lens, and release the shutter.

AE (Automatic Exposure) Lock

An AE lock button is located between the pentaprism and the ASA ring. To use, press and hold the button while you re-frame the subject and release the shutter.

Multiple Exposures

A Multiple Exposure button is located on the axis of the main switch. Pressing this while cocking the shutter prevents the film frame from being advanced. The Film Frame Counter is also disabled during this operation.

Self-Timer Mode

Self-Timer shooting mode on the Canon EF is activated by first pressing the small Self Timer Lock Button on top of the Self Timer Lever, which will release a catch that will let you turn the self-timer lever out (counterclockwise). Press the Shutter Release to start the time delay, the mirror will flip up, and the shutter will fire after the delay times out.

Stopped-Down Metering

To do Stopped-Down Metering, push the Self-Timer Lever in (clockwise) towards the lens mount housing. This will close the lens aperture to aperture value you set for on the aperture ring of the lens. The lever is spring loaded and it will revert to its original position once you release your finger pressure from the lever.

Mirror Lockup

Mirror Lockup is a two-step process. First set the Self-Timer Lever to its Stopped-Down Metering position (in towards the lens mount housing), hold, then turn the 'L-M' lock lever, located on the lower part of the self-timer to 'M' position. The mirror will stay locked up till you reverse the 'L-M' lever setting, after taking the shot.

Loading and Unloading Film

The Canon EF is fitted with an Automatic Blank Shot Mechanism, which frees you from using the Shutter Release Button when loading the film. The winding (film advance) lever works independently of the shutter button until you reach Frame 1.

Lens Compatibility

Canon EF, Canon FD 50mm f/1.8
The camera is compatible with all breach-lock Canon FD lenses available by 1975, which ranges from a 15 mm fisheye to 300 mm telephoto, including three zoom lenses. Older FL-mount and R-mount lenses can also be used on the EF in manual exposure and stop-down mode.

Using the Camera

An ON/OFF switch on the right side at the back of the top plate sets the meter on, disables the shutter trigger lock removed the lock, and frees the film advance lever to pop out 15 degrees from the camera body.
