Interesting. I'm not doubting what you're saying, cuz my speculation that it was probably for motion-capture was just that -- uneducated speculation. You clearly sound like you know a little more about the subject.
Oh, all good, man! It's fun to think about what the tech can be used for! I may be wrong, but MoCap's usually actually done on a stage pre-rigged with smaller cameras that have live feeds into arrays.
Last year, in San Diego, I shot some live action content for Killzone 3 (Sony) and the two stages that they had Malcom McDowell and Ray Winstone on were just like this. Lots of blaring red lights, etc. The cameras are usually rigged with Sigma zooms and balanced, zoomed, etc.
It's all really wicked stuff! And real time!
I'm curious, though -- I thought Cameron built his own 3D cameras, partially because in order for the 3D to work, the two lenses needed to be really close to each other -- much more close than just smashing two cameras together would allow. Is that wrong?
Not arguing. Sincere question.
Cameron had engineers at Sony construct a rig comprised of F23's, I believe. Not F35, as the F23's are smaller sensors and the deep focus is a great asset to 3D. However, I don't think they built more than four or so. F23's are expensive cameras, they're also large and heavy.
The Epic opens up a new world of high quality image acquisition coupled with the freedom and ease to go handhed or move fast. Where it may take three to four guys to move a 3D rig of F23's, it'll take one or two to grab an EPIC 3D rig and throw it into a different location.
Also, the EPIC's cost a ton less than any other camera in its class. Machined M's are coming in at around 60K or so with accessories that you need to get it moving, Arri's Alexa is 80+ and doesn't come with much at all.
F23's are still in the 100+ range, F65 (although I want to shoot with this sucker) is going to be 200K+ I bet.
There are clear advantages to purchasing 50 EPics (25 3D rigs) that would allow him to really push 3D into places where it may not have gone before, including lower budget productions that normally couldn't afford to shoot in 3D.
Cameron's big deal is that everyone should SHOOT 3D, not post-convert, and this'll be his way of really hammering away at it.
