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.
