i have been using batteries to power my flashes for so many years now... and as assignment grows i am still using batteries because it can power up other devices in my home when i am not shooting.
i do not hope to bleed too much on a new investment.
but i have the following flashes to power.
usually, its only 1 550ex and 1 sb800 in action. the rest is all backup. both flashes drink up the batteries like drinking coke.
so i am wondering which qtm module besides the 2x2 and the few latest one... which other qtm batteries can power both canon and nikon systems.
and of course.. i strongly welcome suggestions to other brands.... besides qtm, because its going to make me bleed and after my purchase of my 70-200...
many thanks in advance...
