Today I tested the time I can shoot with the Leaf Aptus22 connected to the MBP on battery power alone.
One hour was without a problem, after app 70 minutes sometimes a corrupted image came in, after app 80 minutes it was three good one corrupted, three good, one corrupted etc.
So at this moment the real shooting time is app 70 minutes on battery power with the Leaf Aptus 22.
Not so bad but not good, especially because my battery still was for 55% full, would love to be able to shoot till it's really empty, but possibly the power on the firewire connector drops after that time.
Best solution for location work without power would be to shoot on the card and empty the card in between sessions.
With a firewire 800 card reader that is a relative quick process to I think for most people it's a good option (or shoot with a Canon tethered with it's own power).
After the workshops in Hertfordshire I hope to bring the Applejuisz with me that claims to run the laptop 5-6 hours before it goes over to it's own accu pack.
That would mean that I can shoot 6 hours in a worst case scenario which sounds very tempting.
Will update the review on my blog and make a new review there when I bring the applejuicz with me.
