| The EOS-1 series clearly being the professional camera for the EOS system. Over the years there have been several versions of the EOS-1. The original EOS-1 was introduced in 1989 as the first professional body for the new EOS autofocus system. |  Canon EOS-1 (Original version) |
| In 1994 a new improved version was introduced, called the EOS-1n. The camera body itself is simply known as the EOS-1n. When Battery Pack BP-1 is attached, it's called the EOS-1n DP. With the powerbooster PB-E1 attached, it's called the EOS-1n HS. There is also a special version with a fixed mirror called EOS-1n RS (introduced in 1995), capable of doing 10 frames per second. |

| The 1v features some major improvements like the 45-point AF system introduced in the EOS-3. The body is rounder, stronger and again better protected against the environment with new weather seals everywhere. Today this body still is the ultimate 35mm film camera and it will probably be Canon's last film body. Like the 1n, it can be fitted with a battery pack or a power booster. With the PB-E2 power booster and NP-E2 rechargeable batteries it is as fast as the EOS-1nRS at 10 frames per second. |  Canon EOS-1v |

With the start of the new millenium the EOS-1n itself was succeeded by the all
new EOS-1v.
