The new Sony 4k PXW-Z100 and FDR-AX1 4k cameras

Here's a clip from Alister Chapman at IBC about the new Sony 4k PXW-Z100 camera - and at about 2:30 they talk about why you would use the PMW-200 over this jobber!

So don't feel so bad!  You probably have a better camera!  Unless you have client clamoring for 4k…..

But seriously, 4k on a less-than-half -inch chip!?  I notice all the demo shots are wide, because if they shot close you would see how video-y it will look.  Still, pretty cool.

What I have been imagining is a camera like the EX3 with (3) 4k chips, or one big one.  Been looking again at the FS-700, as they have enabled the 4K capability on that, and it looks pretty.  Super 35mm sensor as in the F5 and F55.

A quick way to explain the Bayer sensor deal (almost all of these large single-chip cameras nowadays are Bayer sensors) is:

"One thing to remember is that because of the nature of a Bayer sensor you need the sensor to have a higher pixel count than the final desired resolution. Typically you want at least 30% more pixels than your target resolution. As a minimum for good 1080 you want around 2.5K-2.7K pixels."

That's also from Alister Chapman, a cameraman/blogger who knows his stuff.  So when the REDs of the world are bragging on their latest mega-mega-pixel sensor, you have to ask, "how many REAL pixels is that?"
