The Chinon CE-3 Memotron is a 35mm electronic SLR camera made by Chinon and introduced c.1978 as the last in the Chinon CE Memotron series. It's among the small number of 42mm screwmount cameras to offer aperture-priority autoexposure. One change from the CE II version is a switch to a more common and easy-to-find battery type.

The CE-3 was also sold under the name of Revueflex AC1 and some other brand names.
