i think that its less about battery power and more about distractions...
intereetsingly sunday night at this gig i was at a guy was behind me using a nikon f65 (a multi-program starter slr), with a 28-80mm f3.5 lens with no flash. I was quite intrigued, but i doubt he got any real photos...
Also another guy had a canon dslr with an antique flash (which wasnt doing much for him...), but he also had a holga round his neck, the version with the f8 lens, i dont know what he expected to do with that unless he was hoping to catch someone else's flashes
