Olympus Zuiko 35-70mm f/4 Auto Focus
Stand alone autofocus lens to turn any Olympus OM manual focus camera into an autofocus unit. By pressing the buttons on the side of this lens the built in CCD sensor, microchip and focus motor are activated to detect focus anomalities and correct focus when necessary.
The electronics and AF motor are powered by three AAA size batteries in the built-in battery compartment.
In combination with the OM-30 (OM-F) this lens turns into a dedicated unit that can also be controlled by the shutter release button.
The lens also has a normal focusing ring for manual focus; alternatively a Power Focus mode can be selected to control the focus mechanism with two buttons.
