How about the Hyperdeck Shuttle 2 as external recorder?

Yea... much cheaper than the Atomos, albeit without a built-in monitor, but a good option for those who are happy to use the camera's screen, or already have a monitor they're happy with. I just wish the Hyperdeck could do >30fps for 10-bit 4:2:2. Perhaps a new (but still affordable) model will be unveiled at NAB, or if we're lucky, a firmware update.

Advantage of Nikkors is that you can use them in combination with a speed booster on a G6. So if you are thinking about getting a speedbooster Nikon would be a better choice.

There's a SpeedBooster for Minolta lenses, too, you know.

Expressing the increase in brightness via F-stops ("turns your lens into a f0.74!!!!") is what's so confusing for people, because people tend to think of DOF in terms of F-stops. I think people have a better grasp of differences in DOF if they are expressed via sensor sizes:

The easiest way to think of the speed booster is by acting like it modifies the sensor.  Giving the BMCC an APSC crop factor. Giving the same depth of field and noise as an APSC camera, but giving a brighter image for a given iso.

Exactly. For FOV and DOF, think of the Speedbooster as attaching to and modifying the camera, not the lenses. Meaning, think of your camera as now having a larger sensor (exactly how much larger depending on which SB model you're mounting to it).

For exposure (brightness of image), think of the Speedbooster as giving your camera a "free" improvement in ISO (meaning a brighter image but with no additional noise/grain). So you think of any given ISO on your camera as one stop (or 1&1/3 or 1&2/3 stops, for these new SB's) brighter, but with the same noise.

So, if I have a Pocket, and get the new Pocket-specific Speedbooster, I will think of it as turning my sensor into a 1.74x crop/slightly-smaller-than-Canon-APSC/slightly-larger-than-GH2 size, and making the ISO performance 1&2/3 stops better.

Amazing! Hopefully they eventually do a Minolta MC/MD version.

Consumers probably won't even be considering the GH4, as it will be part of the Panasonic pro/prosumer line, not the consumer line. Most of them won't even know of its existence because it won't be at the normal consumer outlets- Best Buy, etc. But the true successor to the GH3, the GH5 or whatever they call it, will be, and it certainly will have 4K, but probably just at 8-bit 4:2:0. And of course at a high consumer price point, say $1400-1500.

I don't see how a GH4 could do 4K 10-bit 4:2:2 at only 200mb/s. ProRes 1080P 4:2:2 is 220mb/s... and intraframe of course, but it's still only a quarter of 4K's resolution. It seems like 4K would have to have a ridiculously long GOP to fit into 200mb/s at 10bit/4:2:2, which would make motion look weird. Personally I would greatly prefer to have an excellent all-i 1080p with lots of detail and color info and frame rates, than an uber-compressed 4K. Hopefully the cam will at least give us both.

I too am awaiting the GH3 user's guide! New camera announcements and theories are great and all, I follow them as much as anyone else, but I want help with using a camera that's available right now. Please finish up that GH3 guide!
