The Riva Zoom 75w (also known as the Freedom Zoom Explorer EX) is a fully automatic compact camera with zoom lens and built-in pop-up flash. It was a minor upgrade from the very similar Riva Zoom 70W with a slightly longer focal range. With this model it stretches from wide angle (28mm) to portrait (75mm) with maximum apertures of f/3.5 to f/8.9. It automatically recognizes the DX-coded ISO speed between 25 and 3200 from the 35mm film capsule. Exposure control, focusing and film transport are fully automatic. The lens allows "macro" exposures (min. distance 40 cm), and the flash has multiple modes: off, on, automatic, red-eye reduction. Focusing and exposure lock are triggered by pressing the shutter release halfway down. The camera was sold in a crowded market in which many compact autofocus zoom viewfinder cameras offered a similarly medium-high quality. The camera has a mighty little flash, reliable automatic functions, but a slight sharpness weakness in portrait focal length and cushion distortion in wide angle focal length.
