35mm Focal-Plane Shutter SLR Camera

EOS RT  [A] [E] [J]
Marketed October 1989
Original Price 115,000 yen (body)

"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.
