What are the differences between an OM-F and an OM-G?
The OM-F differs from the OM-G in the following ways: focusing aid LED’s in viewfinder, F2/F4 switch for focus system, In-Focus trigger cord socket, automatic focus with the Zuiko 35-70 AF zoom, no PC flash socket, and no exposure compensation warning. The OM-F also takes 5 SR44 batteries which mount in a compartment on the left hand side of the front of the camera. In place of the normal battery compartment is a switch to turn off the beeper.
