I’m also very impressed with the 2K slow-mo at 96fps. It is an improvement on the KineRaw MINI from last year which only shot 96fps at 720p, though there is still some moire and aliasing at the higher frame rate.
One of the enigmas emerging from the A7S is whether you can shoot 4K in APS-C crop mode as well. APS-C is Super 35mm in cinema language. I really would like to use my Cooke S4i Minis via a PL adapter on this camera! Taking advantage of the low light sensitivity. APS-C crop mode would also allow the use of standard Sony E-mount / NEX lenses, Canon EF-S and Nikon…
It looks like the story of 2014 is taking shape in the form of very high quality 4K on large sensor mirrorless cameras. Last year for me it was raw on the 5D Mark III which excited me the most and before that it was the Blackmagic Cinema Camera. This year is more exciting on the tech and creative front than any I can remember. Here’s my look at how…
Blackmagic are launching not none, not one but TWO new cameras at NAB 2014. One as you can see packs quite a punch with a quite revolutionary design. The aim of the URSA is to take all the accessories you’d normally rig onto a Blackmagic Cinema Camera and integrate them. That is a sensible idea. However the execution looks to have produced a 7.5KG monster. There’s even an HDMI version…
Breaking news… The Sony A7S has been announced at NAB 2014. It records 1080p internally in XAVC-S format at 50Mbit but the big news is the support for full 4K output via HDMI to an external recorder. Unfortunately it does NOT have an internal 4K recording codec like the Panasonic GH4.

As we get closer to the press conference, more unconfirmed rumours on the A7S have come in from NAB.
