This camera introduced the newly-developed, Multi-BASIS AF sensor which provided three autofocusing points.

One-Shot AF and predictive AI Servo AF are featured as AF modes. In the Full Auto mode, the camera detects whether the subject is still or moving with signals received from the Multi-BASIS. The AF mode is then set automatically.

The three focusing points are red LEDs in the viewfinder’s image area. They are easy to see and any focusing point can be selected manually with a button and dial. A bar-code book was also provided to enter the bar-code for camera settings needed to achieve the effects shown in the book’s sample photos.

Type 35mm focal-plane shutter multi-mode AF SLR camera
Picture Size 24 x 36 mm
Normal Lens EF 35-135mm f/4-5.6 USM
Lens Mount EF mount
AF System TTL phase detection. AF modes: One-Shot AF and predictive AI Servo AF. When the Full Auto mode is set, subject movement is detected and the AF mode switches automatically between One-Shot AF (for a still subject) and AI Servo AF (for a moving subject). Even in the One-Shot AF mode, focusing is continuous. If the subject starts to move, the Predictive/AI Servo AF mode takes effect automatically. AF operating range at ISO 100: EV 0 – 18. Multi-BASIS (3 focusing points ) for the AF sensor.
Shutter Vertical-travel, focal-plane electronic shutter. 30 sec. – 1/4000 sec., B. X-sync at 1/125 sec. (hot shoe). Shutter speed can be set in half-stop increments. Built-in electronic self-timer (with blinking LED). Built-in interval timer for intervals from 1 sec. to 23 hr. 59 min. 59 sec. for frames 2 to 36.
