if you are shooting with d-slrs as well as video cams I’d thing you’d do well to consider a compact video light that can mount on all your cameras hotshoes as well as any off camera lights you think will fit your needs….
I find by having a video light on my d-slr hotshoe I can work in low light and switch-hit from stills to video quickly..
I went with a small sony unit that runs on AA’s because I try to limit how many propriety batteries and chargers needed… My portable flashes and video lights as well as my video d-slrs (pentax kr’s) all take the same batteries AA nimh rechargeables…. a fast charger and smart charger and eight sets of batteries in one kit bag…
then my sony camcorders and accessories in another kit bag, and lastly my stills d-slrs in another bag…
trust me, on a shoot is no time to be looking for a propriety battery when you’re running multiple cameras/systems, and accessories! especially if you find your self with ten fully charged batteries and the one you need is dead! lol!
