Aimed at the professional market, the EOS 1 is notable for being a major game changer for Canon. For the first time ever, Canon's standard USM lenses offered better focusing performance than Nikon's professional lenses on the then-inferior Nikon F4.
The EOS-1 (1989) was succeeded by a few improved models and variations:
- EOS-1n (1994), with improvements in focusing system and various iterative improvements.
- EOS-1n RS (1995), with a pelicle mirror similar to that of the EOS RT and older Pelix.
- EOS-1v (2000), the final version, and the fastest SLR camera with a moving mirror.
The last in the series, the EOS-1v is still in production as of 2010, making it one of the longest production runs for a camera in recent history. Its digital successors include the EOS-1D and brethren Mark I-IV, themselves very heavily based on the 1v.
