My understanding is SLRs are very common for miniatures using motion control and/or stop motion. Lots of tools support canon DSLRs primarily for automating precise capture. And effects shots really benefit from the extra resolution. Also still cameras are used for VFX such as capturing mirror balls etc. Many reasons to have DSLRs on set on such a movie.
That's not really the case anymore, is it? There are LED fresnels and pars now. Even a 1x1' LED light isn't that hard to control with barn doors or flags since it's not really all that large, and large and diffused leds can still be controlled with with eggcrates like any soft light.
Is it really only 2 watts? That must be the worlds most expensive LED per watt :P
If you're looking for more info, I've been testing these lights over the past 9 months and posting about it on here: http://www.dvxuser.com/V6/showthread.php?349097-New-Flexible-LED-Panels
Not really, the wondlan ff+monitor is >$2k and this thing should really hope to be better than the wondlan follow focus or else it is nearly useless. The wondlan FF requires a separate receiver box to be mounted on your rig, and from what I understand it is way louder than any normal professional wireless follow focus. In the tests I saw it made a pretty loud high pitch whine. Then again neither of these look like they could stand much abuse and I wouldn't be surprised if the lenzhound was pretty loud as I haven't seen any videos in which you can see it operational and get a sense of the noise it makes...
