Autofocus 35mm SLR camera introduced in 1985, known as the Maxxum 7000 in North America and 7000 AF in Europe.

Overview

The Minolta Alpha 7000 is a 35mm autofocus SLR camera produced by Minolta from 1985 to 1988. It was released in Japan under the name Alpha 7000, while the same model was marketed as the Maxxum 7000 in North America and the 7000 AF in Europe. This camera is recognized as the world’s first autofocus SLR with an in-body motor, marking a major advancement in SLR design by integrating autofocus directly into the camera body.

Design

The Minolta Alpha 7000 featured a blocky, angular design made of black polycarbonate with prominent buttons and dials, giving it a futuristic appearance for its time. It was controlled by two 8-bit microcomputers that managed autofocus, auto multi-program exposure, film transport, and LCD data displays. Each compatible Minolta AF lens included a ROM IC to send over 30 lens parameters to the camera’s computer for accurate autofocus and exposure control. The camera also included a built-in lithium cell for memory backup with an estimated 10-year lifespan.
