NAB was massive, both in the number of people attending and the sheer volume of products and technology on display. The headline for video producers was all about HD - it was everywhere, and it seems like there never was such a thing as SD or film. The products are flooding the market, but workflow issues are still very tricky.
I'm in the market for a HD camera and I was leaning toward the Panasonic AG-HVX200, but for documentary work in the field, I don't think it's the right camera. Thankfully, there are lots of good alternatives out there.
