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.

Only a few years ago S-LOG was a $3800 upgrade for the Sony CineAlta F3, itself a $15,000 camera. 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 which can be applied in Premiere, Resolve, etc. for an instant cinematic look to your A7S S-LOG 2 footage.

Three LUTs are provided in the zip. Dynamic – for best dynamic range, will suit a low contrast shot requiring high dynamic range and plenty of shadow detail. Also good for low light. Vivid will give a punchier look to those shots that benefit from it like a sunset and where some dynamic range can be scarified for higher contrast and saturation. S-GAMUT is for when shooting S-LOG with the Color Mode of S-GAMUT and compensates for the purple tint to reds I find I am getting in this mode. For the Dynamic and Vivid LUTs you must set the camera colour mode in PP7 to ITU709 Matrix.

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)

Just how is the rolling shutter exactly on the A7S - intolerable or similar to what we’re used to on other DSLRs?

gh4 vs 5d mark iii dxomark

DXOMark have tested the raw sensor output of the GH4. Raw stills have 12.8 stop dynamic range vs 11.7 stops on the 5D Mark III, illustrating just how far ahead almost everyone is on sensor performance over Canon.
