It was the first SLR to use a body completely cast of plastic, and the first camera to use the, then-new, DX encoding for film sensitivity.
It is fully mechanical and a basic SLR with a CdS TTL light meter, Shutter-priority, and auto-exposure. Shutter speeds were from 1/8s to 1/1000s and Bulb. It uses the Konica AR bayonet. While it makes use of a battery, the battery is only needed for the light meter, it can use AA or AAA alkaline, depending on the model.
