Chinon CE-3 Memotron (c.1978)

A compact 35mm electronic SLR with aperture-priority automation and an M42 screw mount

Overview

The Chinon CE-3 Memotron is a 35mm electronic SLR introduced around 1978. It was the final model in the Chinon CE Memotron series, and it was also sold as the Revueflex AC1. It does semi-automated shooting with aperture-priority mode and stop-down metering, which makes it one of the few M42-mount cameras that can. It has a built-in memo holder and three focusing aids: split image, microprism, and scale focusing. Lenses mount on the M42 screw mount, which takes Pentax/Practica-type lenses.

Design

The CE-3 Memotron is an electronic SLR with a compact body and a built-in memo holder for shooting notes. The M42 screw mount supports aperture-priority automation with compatible lenses. Stop-down metering is what makes the semi-automated exposure control work.

Context

The CE-3 Memotron was positioned as the last model in the CE Memotron series, and it was also marketed as the Revueflex AC1. It belongs to a small group of M42-mount SLRs that can do aperture-priority automation. Many of its contemporaries needed fully manual operation with stop-down metering.

Market

One recent listing priced a Chinon CE-3 Memotron at €105.00, with the body and original box. It has appeared in collections with noted photo rarity index value, and film photographers still use it with various M42 lenses.
