3. Conserving battery power

The experienced E-2 user will know that the main power drain on the camera comes from the use of the motorised focus. Using the camera at a fixed focus, for example when shooting the same scene with different subject matter e.g. table top pack shots , can save power by preventing the focus servo from hunting as the subject is changed.

Another major power drain occurs when sending a video output from the camera (playback in the E-2/E-2s or preview and playback on the E-2N/E-2Ns). It is recommended to use the AC power supply if possible when requiring video output from the camera.
