On saturday I went from full charge to flat.

The battery lasted for 102 mins [1] recorded 18GB at
1920?*?1080, H.264, AAC


which worked out at about 5 1/2 mins per GB

Mostly manual focus, most vids between 4-13 mins each.



[1]Well 4 photos too but not really relivant to battery life

Just wondering - how is your M3 at auto focussing?
I use mine with the adapter and my L lenses from the other Canons, and
autofocus is useless. Rarely locks in, unless I'm in bright light with
lots of contrast in the image.
