Design History
Beginning with the amateur level Canon AE-1 of 1976, there was a complete overhaul of the entire Canon SLR line. The 1970s and 1980s were an era of intense competition between the major SLR brands: Canon, Nikon, Minolta, Pentax and Olympus. Between 1975 to 1985, there was a dramatic shift away from heavy all-metal manual mechanical camera bodies to much more compact bodies with integrated circuit (IC) electronic automation. In addition, because of rapid advances in electronics, the brands continually leapfrogged each other with models having new or more automatic features, and less expensive components and assembly. The industry was trying to expand out from the saturated high-end professional market and appeal to the large mass of low-end amateur photographers keen to move up from compact automatic leaf shutter rangefinder cameras to the more "glamorous" SLR but were intimidated by the need to learn all the details of operating a traditional SLR.
The A-1 is the high technology standard bearer of the landmark Canon amateur level A-series SLRs. The other members of the A-series are the Canon AE-1 (released 1976), AT-1 (1977), AV-1 (1979), AE-1 Program (1981) and AL-1 (1982). They all use the same compact aluminum alloy chassis, but with differing feature levels and outer cosmetic acrylonitrile-butadiene-styrene (ABS) plastic panels. By sharing most major components, and an inexpensive horizontal cloth-curtain shutter, costs could be spread out over a larger production volumes. The A-1 represented Canon's bid to defeat Nikon through more features and the cheapest price.
The A-1 caused a sensation when it was released in early 1978. Most photographers were amazed at its advanced features, years ahead of the competition, but in the face of changing technology, not all comments were positive. Professional photographers worried about the long term reliability of its consumer-level mechanical and electronic components under heavy daily use, the relatively slow flash sync and top shutter speeds. Traditionalist photographers complained about an "excess" of automation ruining the art of photography, a criticism that was leveled at all of the newly-automated cameras released in the 1980s. However, automation turned out to be the right way to entice many new amateur photographers on a budget, and paid off very well for Canon.
The Canon A-1 was a runaway best seller, as it offered new SLR buyers considerable features and value for the price. It was reliable for its day in amateur usage. But as competitors brought out their own programmed SLRs, the A-1 began to show its age. This is especially true for its horizontal cloth-curtain shutter, viewfinder information display and autoflash control. The A-1 was due for replacement when the Canon T90 came out in 1985. Canon's abandonment of the FD lens mount for the EOS design also had a significant effect on demand for the A-1 on the used market. But it is still regarded as one of the most fascinating SLRs of its generation and many are still in regular use.

Famous quotes containing the words design and/or history:
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“In every election in American history both parties have their clichés. The party that has the clichés that ring true wins.”
—Newt Gingrich (b. 1943)
