The Canon FD 35-70mm f / 4 AF lens, released in 1981, was Canon's first attempt at adding autofocus capability to their range of single-lens reflex cameras.Canon took their existing, successful Canon FD 35-70mm f/4 lens and added a box above the lens which housed a self-contained autofocus mechanism, Canon's SST (Solid State Triangulation) system, as used in the AF35ML compact camera earlier ...
The Canon AL-1 was an FD mount, 35mm single-lens reflex camera introduced in March 1982. [1] [2] Its main feature was the "Quick Focus" focus-assist system [3] that was aimed at those who had trouble focusing through the viewfinder—either novices, or those with poor eyesight—and was intended to head off competition from the first full-autofocus cameras from other manufacturers, such as the ...
Phase-detection autofocus "sees" through window glasses without problems and is much more accurate, but it does not work in low-light conditions or on surfaces without contrasts or with repeating patterns. A very common example of combined usage is the phase-detection auto-focus system used in single-lens reflex cameras since the 1985s. The ...
The Canon AF35M, by Canon Japan or the Sure Shot by Canon USA, was Canon Inc.'s first autofocus 35mm lens-shutter compact camera. [ 1 ] [ 2 ] It was launched in November 1979 [ 1 ] and received the Japanese Ministry of International Trade and Industry's 1980 Good Design Award in September 1980. [ 2 ]
The lens has a self-contained autofocus system that does not require autofocus electronics in the camera body. Canon, unlike Minolta and Nikon, was convinced that having the motor in the lens was the optimal approach; this line of thinking continued with the new EOS system in 1987, which remains Canon's standard mounting system for SLRs today.

For example, the Canon EF 50mm f / 1.8 II or Nikon AF Nikkor 50mm f / 1.8D are very inexpensive, but quite fast and optically well-regarded. Old fast manual focus lenses, such as the Nikkor-S(C) or Nikkor AI-S 50mm f / 1.4, or Canon's FD and M39 counterparts, were historically produced abundantly, and are thus sold relatively inexpensively on ...
For example, as of 2008, Nikon cameras allow one to set the maximum and minimum ISO sensitivities, and slowest shutter speed that will be used in automatic modes, [4] while Canon cameras will select within the fixed range of ISO 400–ISO 800 in Auto ISO mode. In Nikon cameras, the Auto ISO mode first adjusts the shutter speed, keeping ISO at ...
