A British film, Belle, is the first in the UK to be shot in true 4k with Sony's F65 camera

Sony has been teasing us with glimpses of their new 4K delivery system since shortly after they released details of their 84" 4K Bravia TV. Concrete details have been thin on the ground, and we still don't know what the final product will look like. And there's a bigger question as well…

A day is a long time in digital video technology. And what we now know is that the battle-lines have been drawn for the fight over 4K delivery. Is this simply a squabble between obscure and proprietary systems, or the end-game in the democratisation of cinema that started with the RED One, and blossomed into the plethora of affordable cameras that start with DSLRs and go all the way up to the new Sony F55?

Sony are launching a new version of their "Anycast" production switcher, the AWS-750. It is smaller and lighter than its predecessor and features an innovative dual touch screen control surface 

Sony caught the entire industry on the hop with their low list pricing for the recently-announced F5 and F55 4K-capable cameras, but now we're seeing the first street prices, and they are, of course, even lower!

Sony was in a difficult position when they presented their press conference today at the Mirage Ballroom in Las Vegas. They've already announced their F5 and F55 4K cameras in October last year (they've already sold 2000 of them) , and no-one was really expecting any ground-breaking news from them today. But that doesn't mean that the content of the news conference wasn't important, because the underlying seismic movement towards 4K was solidified by a few of the more subtle comments

Sony begins to flex its 4K ecosystem. What's an ecosystem? It's what happens when content owners also control the means to distribution.

Sony had a lot of announcements at NAB, one that you might have missed was the establishment of a new subsidiary, Sony Cloud Media Services, with a package of cloud based tools for content creators 

We've already reviewed the FS700's slow motion capability and now (thanks to @sonyproeurope for bringing this to our attention) it's been used together with an FS100 to capture the colour and spectacle that is a Coldplay stadium gig.
