An improved version of the EX EE, the EX AUTO was very popular with beginners who previously had difficulty understanding SLR cameras. The EX AUTO had maximum-aperture TTL metering and shutter speed-priority AE.The lens' maximum aperture f-number was corrected automatically when the lens was attached to the camera. Another improvement was the addition of the EX 125mm f/3.5 interchangeable telephoto lens.
The lens focusing ring was also coupled to autoflash metering. With the dedicated Speedlite D mounted on the hot shoe and the EX 50mm f/1.8 lens attached to the camera, the CAT System automatically obtained the correct flash exposure for the subject distance. Taking pictures at night became as easy as taking pictures during the day.
