Canon Ae-1 Program Exposure Lock
Aug 13, 2013 Canon A-1 vs Canon AE-1 Program. Discussion in 'Canon FD' started by paul_wheatland, Feb 9, 2013. I think the Canon AE-1 Program was one of the largest production runs in SLR history, at least. My complaint about them is that in Aperture Priority mode there is no exposure lock. Thie leads me to use plain F-1s more often. I do not enjoy.
- The Canon AE-1 is a 35mm film SLR camera with shutter-priority automatic exposure and manual override, produced by Canon in Japan and produced between 1976-1984. By using a microprocessor, Canon was able to simplify the design, and by using a highly automated production process, they were able.
- The AE-1 has a Canon FD breech-lock lens mount and. It supports either manual exposure control or shutter priority auto exposure. Canon AE-1 with lens cap of.

2. The AE-1 PROGRAM's battery checkcircuit not only tells you whether the battery is good but also how good it is. First make sure the main switch is on 'A.' |
Then press the battery check button for two to three seconds. If the battery's power is sufficient, the camera will emit about six or more 'beeps' per second. If the battery is weak and needs replacing, the camera will beep at the slower rate of about three 'beeps' or fewer per second. 3. The battery is exhausted if, after pressing the battery check button for about three seconds, no sound is emitted. Replace the battery with a new one. 4. Pressing the battery check button, the shutter button, the exposure preview switch, or the AE lock switch uses battery power. Take care that nothing presses on any of these when the camera is not in use. 5. Remove the battery if you do not expect to use the camera for about three weeks or longer. With normal use, the battery should last about one year.

Viewfinder Information for Canon AE-1 Program
The AE-1 PROGRAM's viewfinder is especially bright to facilitate viewing and focusing. It displays only the necessary information, using a Light-Emitting Diode (LED) system of illumination. The degree of LED illumination changes in four stages depending on the brightness of the subject. When the subject is brighter, the LED brightness is slightly higher; it is slightly lower with a darker subject.
Thus the LED maintains an almost consistent degree of brightness to the human eye. |
Correct exposure is provided by the Central Emphasis Averaging System (Also generally referred as 'center-weighted average metering'), which reads the entire viewing area with emphasis on the central portion where the subject is most likely to be placed. Since a new type of split-image rangefinder is used in the center of the viewfinder, the brightness of the split-image rarely changes even when using a lens whose maximum aperture is f/5.6 or smaller.
Out ot Focus |
In Focus |
The laser-matte screen appears fuzzy until the subject is in focus. It is particularly effective when you are using accessories for copying or close-ups. Canon offers eight different types of inter-changeable focusing screens. When using a lens with a maximum aperture of f/5.6 or smaller, half of the split-image rangefinder may take on a slight color.
Note*:When the lens aperture ring is set to 'A' and the shutter speed selector dial to 'PROGRAM,' a green 'P' LED is displayed, indicating programmed AE photography. Note**: Other than the standard split image/microprism rangerfinder screen. Canon has designed seven other types of focusing screens for the AE-1 program to suit various photographic needs, these screens are user interchangeable (Unlike the Canon A-1 which requires factory technician or a experienced serviceman to change).
If the shutter speed selected automatically by the camera is 1/30 sec. or slower, the 'P' will blink. This is to warn you that your picture may be blurred due to camera movement if you are hand-holding the camera. The aperture selected automatically by the AE-1 PROGRAM is displayed in the viewfinder. The meter index is for setting exposure with a non-FD lens and in close-up photography. When using a Canon Speedlite 011A, 133A, 155A, 166A, 177A, 188A, 199A, 533G or 577G, a green flash charge-completion signal lights up when the flash is charged.
When using the Speedlite 188A or 166A, this signal flashes on and off for two seconds after the shutter is released if the flash-to-subject distance was within the auto coupling range. |
Meter coupling range
When using an FD 50mm f/1.4 lens and ISO/ ASA 100 film, the built-in exposure meter couples within a range of EV1 (f/1.4 at 1 sec.) to EV18 (f/16 at 1/1000 sec.). At given film speeds, the built-in exposure meter couples with the aperture and shutter speed, as indicated in the chart on the next page. If the shutter speed and aperture combination are outside the coupling range, the camera warns you by flashing the appropriate display inside the viewfinder.

The Canon AE-1 is a 35 mm single-lens reflex (SLR) film camera for use with interchangeable lenses. It was manufactured by Canon Camera K. K. (today Canon Incorporated) in Japan from April 1976 to 1984. It uses an electronically controlled, electromagnet horizontal cloth focal plane shutter, with a speed range of 2 to 1/1000 second plus Bulb and flashX-sync of 1/60th second. The camera body is 87 mm tall, 141 mm wide, and 48 mm deep; it weighs 590 g. Most are black with chrome trim, but some are all black.

Features[edit]
The AE-1 has a Canon FD breech-lock lens mount and accepts any FD or New FD (FDn) lens. It is not compatible with Canon's later Canon EF lens mount, though adapters made by independent manufacturers can be found. The camera will also accept Canon's earlier FL-mount lenses through the use of stop-down metering.[2] Original FD lenses, introduced in 1971, did not rotate in the mounting process; instead, a locking ring at the base was turned to attach the lens. This was often criticized as being slower than the bayonet mounts of competing cameras.[1]:201 The counter argument, though, was that as the lens/body mating surfaces did not rotate, there was no wear that could affect the critical distance from lens to film plane. In 1979, Canon introduced the New FD series of lenses that rotate the whole outer lens barrel to lock. The inner lens barrel remained stationary, and thus the signal levers and pins still did not rotate. During the late 1970s, there were over 50 Canon FD lenses available for purchase. They ranged from a Fisheye FD 15 mm f/2.8 SSC to a FD 800 mm f/5.6 SSC, plus special purpose lenses such as a 7.5mm circular fisheye and a 35 mm tilt and shift lens.
Accessories for the AE-1 included the Canon Winder A (motorized single frame film advance up to 2 frames per second), the Canon Databack A (sequential numbering or date stamping on the film), and the Canon Speedlite 155A (guide number 56/17 (feet/meters) at ASA 100) and Canon Speedlite 177A (guide number 83/25 (feet/meters) at ASA 100) electronic flashes. The later Power winder A2 was also compatible, but the Motor Drive MA was not.
The AE-1 is a battery-powered (one 4LR44 or 4SR44) microprocessor-controlled manual focus SLR. It supports either manual exposure control or shutter priority auto exposure. The exposure control system consists of a needle pointing along a vertical f-stop scale on the right side of the viewfinder to indicate the readings of the built-in light meter (center-weighted with a silicon photocell). The viewfinder used by the AE-1 is Canon's standard split image rangefinder with microprism collar focusing aids.
Design history[edit]
The AE-1 was the first in what became a complete overhaul of Canon's line of SLRs. The 1970s and 1980s were an era of intense competition between the major Japanese SLR brands: Canon, Nikon, Minolta, Pentax and Olympus. Between 1975 and 1985, there was a dramatic departure from heavy all-metal manual mechanical camera bodies to much more compact bodies with integrated circuit (IC) electronic automation. In addition, due to rapid advances in electronics, the brands leap-frogged each other with successively more automated models.
Although Canon Camera K. K. had been making quality 35 mm cameras for decades, it had always been overshadowed by their rival Nippon Kokagu K. K. and their Nikon cameras. While Canons easily led in the amateur compact fixed-lens rangefinder market (where Nikons did not compete), Canon SLRs had far less cachet than Nikon SLRs. Nikon, with its solid reputation for quality of material and workmanship, held a stranglehold on the prestigious professional SLR market that competitors could not break.
The AE-1 was the vanguard of the landmark Canon amateur level A-series SLRs and led Canon's charge into the emerging electronically controlled SLR market. The other members of the A-series were the AT-1 (released 1977), A-1 (1978), AV-1 (1979), AE-1 Program (1981) and AL-1 (1982). They all used the same compact aluminum alloy chassis, but with different feature levels and outer cosmetic plastic top panel. By sharing most major components, including an inexpensive horizontal cloth-curtain shutter, viewfinder information display, and autoflash control, Canon further reduced costs and could undercut the price of the more expensive SLRs then on the market.
In keeping with its cost-cutting philosophy, Canon designed the AE-1 to use a significant amount of structural plastic for a lighter and cheaper camera at the expense of being less impact resistant. Canon went to great effort to disguise the use of plastic - the injection-molded acrylonitrile-butadiene-styrene (ABS) for the top panel finished with either satin chrome (or black enameled) to give the look and feel of metal. The bottom plate were made of brass and then finished with satin chrome (or black enameled). Extensive use of electronics also allowed simpler modular internal construction instead of mechanical linkages. Five major and 25 minor internal modules reduced the individual parts count by over 300. Modular construction, in turn, allowed automated production lines in order to reduce cost. Unfortunately, cost concerns also resulted in the use of plastic in some of the moving/operating mechanisms.
The AE-1 was never designed to be a professional camera. However, it was made to have relatively straightforward controls and automatic aperture for newcomers, with various manual controls and system accessories to appeal to more experienced photographers. The AE-1 was the first SLR purchased by millions of amateur photographers, persuaded by its feature list and low price.
In many ways, the AE-1 represented the confluence of two streams of Canon camera development. The first generation electronically controlled 35 mm SLR Canon EF (1973) merged with the final generation rangefinder Canonet G-III QL17 (1972). After decades of chasing Nikon for Japanese optical supremacy, Canon finally hit upon a formula for success: high technology for ease of use, cheaper internal parts and electronics for lower price, and heavy advertising to get the message out. Despite outcries from traditionalist photographers who complained about an “excess” of automation ruining the art of photography, automation proved to be the only way to entice the amateur photographer.
The AE-1 had only one pointer needle used to indicate the light meter recommended f-stop, and neither a follower needle to indicate the actual lens set f-stop, nor plus/minus indicators for over/underexposure. The shutter-priority system of the AE-1 was more suited to sports action than to preserving depth-of-field, yet the 1/1000 s top speed of its horizontally traveling shutter limited its use for such activities. The battery door design was subject to frequent breakage, and over time owners have reported instances of shutter and mechanical gremlins, including mirror linkage wear (the 'Canon squeal'). Canon's eventual abandonment of the FD lens mount for the EOS autofocus design also had an effect on prices for the AE-1 on the used market.
