that is pretty sweet, but i fail to see where 3 7d's come in handy, let alone 5 bodies(still jealous) are you triggering them remotely at events or something? or did someone else throw their 7d in for the photo
(4 bodies is still a lot!)
i use 2 camera at a time, 1 for long and 1 for wide, and jumping between the 2 can get sketchy at times, just think of holding 5 bodies and lenses at once
thats y i ask if ur remotely triggering them.
either way
to you sir!
