I'm using the GP 1600 nimhs, took about 70+ night shots with all those zoom in , zoom outs, focusing etc. And the batteries indicator is still showing full blocks. Good Deal!

The viewfinder definitely contributes a lot to this low battery consumption thingy. Since most of the infos are shown on the viewfinder, I hardly use the LCD screen.

Olympus just refused to officially recognised the microdrive support for E10.
