>>2693195I'm actually really happy with it, but it's the only one I've used. There's flicker that anything faster than 1/120 or so will catch, but I'm shooting at .6 seconds and it's working great.
>>2693211 You might be right, I haven't done much of this before and I pretty much pulled it out of my ass. That said, I'm doing .6 sec exposures which are definitely slow, but not battery-eating slow. It lasts longer than my motivation on any given evening. The camera is an NEX-5R which goes pretty cheap on KEH and has had the shit beat out of it anyway, so if it's damaging the sensor I'm not super concerned. Using an IR remote, camera shake hasn't been a problem at all.
I think a feeding system would be more fiddly than this method. Repositioning isn't bad at all, you settle into a move-shoot rhythm that only needs a couple seconds per shot.
Light evenness and color don't seem to be a problem, but I'm not that good at the post processing side of it yet so it may be that I just don't know any better.
