Canon EOS RT - Camera

Canon EOS RT - Camera

The Canon EOS RT is a 35mm SLR camera produced by Canon from 1989 to 1992. The camera is essentially an EOS 630/EOS 600 with a pellicle mirror. It was the first autofocus camera to feature a pellicle mirror.

“RT” stood for “Real-Time.” The fixed pellicle mirror drastically shortened the shutter-release time lag. The camera was developed for pros.

Pressing the shutter button halfway readies the camera for instant picture-taking. It takes only 0.008 sec. for the shutter’s first curtain to open and the second curtain to close after exposing the film. The camera also features a continuous shooting speed of 5 fps, predictive AI Servo AF, autobracketing, multiple exposures, six AE modes and metered manual, and 15 Custom Functions.

Canon EF

Canon introduced the EF mount to the world in 1987. At the time it was the first fully electronic lens mount on the market and offered faster autofocus than the competition. The all-electronic nature of the mount means that the oldest EF lenses will still work properly on the newest bodies without any compatibility issues.

The decision to completely scrap the FD mount was not a popular one at the time, but it allowed Canon to wrest control of the professional market away from Nikon.

One of the main advantages of the EF mount compared to Nikon F, Pentax K and Sony A is the shorter flange distance. The EF mount has less distance between the back of the lens to the image plane, allowing for the easy use of lens adapters. A shorter flange distance also allows for more effective wide-angle lenses at lower prices.
