Title: Leaf Aptus 22 ....battery life
Post by: explora56 on August 16, 2011, 08:26:17 am: Well I have my recently aquired 22 fiited to my Mamiya 645 AFD11 all set up after an ititial scare with error db but I eventually reset the camera to factory settings and hey presto all seems to be working OK.

I have 2 new batteries both now fully charged and good to go first foray into the studio on Thursday. Won't be shooting tethered yet.

From experience can anyone tell me what sort of average number of shots I may expect to get from a fully charged battery and any tips on rationalising the power consumption for optimum performance.

Any help advice would really be appreciated.

Bill

And also you can minimize the LCD brightness setting, which has a strong effect on battery life.

Another question.....

I see it is possible to attach an external power supply directly to the back using a firewire adapter for power only....anyone any idea where I can sourse such an item I have searched the net to no effect at the moment.

Yes, with all LEAF backs a power adapter connected to the FireWire 800 is provided (small connector in a form of a L). You can directly connect your power supply used for charging the battery, or the 12V car adapter or bring power via a Quantum battery with the dedicated cable SD16. Cheers, Jean-Luc

You can see the adapter on the left side of the two batteries:
