Re: Sony announces PXW-FS7 4K UHD Camera, This is what the EA50 is as 4K shooter
 

I wonder if the EA-50 lenses and adapters we already have will work?

I would also like to know if this will lead to new e-mount lenses....

Yes, if it's an E-mount, it'll work.
The one caveat is the 18-105 power zoom lens. It can only be used in HD mode with the FS7. 4K will cause it to have distortions and other issues. I think the EA50's 18-200 power zoom is good, even in 4K. But that's just a guess. I used an 18-200 power zoom on an FS700 on a shoot (in HD, not 4K) and it looked just fine.

Yes, there will be more E-mount lenses developed. I believe Sony now groups all E and A mount lenses as Alpha lenses. Either way, use an E to A mount adapter and they're all good to go.

Plus, all the other lens adapters for Canon, Nikon, etc. You can have an amazing variety of lenses for the FS7.

This WILL be the camera for me if (and it's a big IF at the moment) I decide to go 4K because of my EF lens and adapters investment - Expensive at the moment but give it 6 - 12 months on the market and the price will drop.

ND FILTERS - JOY!!!!!

I'd like to know if they've improved the servo zoom speed over the EA50!
