The Olympus AZ-4 Zoom is a 35mm fixed-lens SLR camera introduced in 1989. Overview It appeared in the 1989 Batman film. It is almost identical to the Ricoh Mirai, except it does not have a remote control socket and uses different batteries. It has a built in zoom lens which zooms from 35 to 135mm in approximately 52 steps. The zoom lens moves slowly compared to modern 35mm cameras, and the autofocus is slower and less reliable.

It has the following features usually only found on SLR cameras: Real image viewfinder Manual focussing mode Exposure adjustment Shutter speed adjustment Hotshoe for external flash It has the following features usually only found on compact cameras: Autofocus Built in pop up flash Self timer (Timer to take photo 10 seconds after shutter is pressed) Fill-in flash It also has the following features LCD Beeps when autofocus locks Tripod socket Some models use 2 123 size lithium batteries.
