On a trip to Pinewood Studios I saw for the first time Sony A7S 4K footage projected in a theatre. The surprise was just how well the 1080p held up for cinematic projection. I also had my hands on the Atomos Shogun 4K recorder / 7″ monitor, the new Sony PXW X70 1″ camcorder with 10bit XAVC codec and more…
[vimeo]http://vimeo.com/101260603[/vimeo] I’ve had the A7S for over a week now and can share my initial thoughts, even some firm conclusions. Here’s one I’ve come to already – the Sony A7S is the best consumer camera Sony have ever made. For $2500 the video performance of the A7S sits between the FS700 ($8000) and F5 ($17,000) yet the full frame sensor lends more character and allows for groundbreaking low light performance.

S-LOG made its debut on the Sony F35, a workhorse of Hollywood. Now Sony have put this on a $2500 consumer camera along with the best full frame sensor I have ever used for video. How good is it? Very!! I am sharing a pack of LUTs for the A7S…
The A7S is so close to being a ‘complete’ system for high end video quality in a small prosumer camera, but there’s one issue that has quite rightly been highlighted by filmmakers such as Andrew Wonder and that is the rolling shutter distortion. The A7S actually has a very fast sensor with high efficiency made possible by the latest technology but because it does not skip any lines when reading out…
Picture (“Buddy”) courtesy of James Miller, inset – the CYP 4K HDMI scaler The picture above (click for 1080p original) is from the 4K full frame sensor inside the Sony A7S (ISO 3200, S-LOG2). Internally the camera does a simple downscale of the 4K signal to 2K for standard 1080p XAVC or HDMI recording – but James discovered adding a hardware scaler on the end of the 4K HDMI signal results in a…
Slashcam have chart tested the A7S internal recording modes and the results for the regular frame rates 24-30p are incredibly positive. However it seems that in 60p the camera cannot utilise the full pixel readout of the sensor, which results in a worse image with moire and aliasing. You can read my take on this below or head over to Slashcam to read the original piece (Google translated)
