Concerning F5 battery usage I measured the
following current
F5 left on without metering 0,76 mA
F5 with lighting on 175 mA
F5 with AF usage 250-300 mA
F5 in CH 8 F/s 600-700 mA
My solution as of now:
1. Lithiums for mobile work
2. MC-32 12V adapter and 220V/12V power suppy for studio work
3. MC-32 12V adapter and a YUASA 12V lead gel accumulator for
sports semistationary work.
The MC-32 cable is 2,5m long and doesn´t bother me at all.
My small accu weights 1200 gr and fits into my (nikon) photo vest
and I can also put it on the floor or into a selfbuit cradle on my
tripod.
This setup is - admittedly - heavy but it saves a lot of money for the
lithium batts. When I shot a rhythmic gymnastic competition here it
gave me 40 rolls of 36 slide film with a lot of energy to spare
(almost
continuous AF and metering).
