Sony A7S Video Test

This is the Sony Alpha 7s Mirrorless camera video test. This camera comes with 12 Megapixels Full-Frame Exmor CMOS 4K Sensor. And the high sensitivity goes up to 409600ISO. The reason why I picked this camera because the A7S is the world first 4K full frame camera without any crop factor. I personally like shooting wide angle stuff. But since I stepped forward to the 4K world. I found it is very difficult to shoot 4K wide angle shots. Even the Canon 1DC has got 1.3x cropped in 4K, Black Magic 4K camera has got 1.6x cropped in 4K, and Panasonic GH4 has got 2.3x cropped in 4K. So this camera has got what I want. Another reason why I like the A7s is the lowlight Sensitivity. I shot most of the footages at f/5.6 at night and between 3200ISO to 5000ISO. All the footages looked super clean and sharp. Even though I can't test the real 4K just yet. Because the Atomos Shogun isn't out yet. I believe the 4K should be even nicer. But I'll definitely do another test once I got the recorder.

A7S Pros and Cons (Personal Opinion)
Pros
Full Frame (Do not have any crop factor in 4K)
Full Pixel Read Out
PP7 S-Log flat picture profile
Focus Peaking
Mic and headphone jacks
Extremely great low light performance

Cons
No 4K internally (Requiring an expensive recorder)
50mbps codec still a bit behind comparing with canon or Panasonic
Poor battery life

Hi there, Hong Kong is it? Very good camera work and the post is unbelievably nice. I have tried out the SLOG-2 on my A7S but cannot come even close to your result. What is the secret? Any short cuts or is it just years of practice  that counts?? Thanks again // Ron

very nice video. I'm thinking about selling my 5d Mark 3 and getting an A7S. Did you overexpose the S-log and bring it down again in post, to get less noise in the shadow areas? From what i've heard S-log 2 performs best if overexposed by 2 stops. What's your experience?

great stuff! love your work :) any chance of a gh4 vs. a7s vs. 5d3 raw?  I currently have 5d3 for hybrid video & photos but was contemplating getting a gh4 or a7s...would love a test, especially of human subjects to compare the three :)

[AIexanderHartdegen]

My god. The video looks like shooted on 4k and downscaled on 1080p!!

[vrhomes-floridavacation]

What white balance did you use, did you just set it each time?

[Deanzsyclone]

Jeez such amazing low light, I wonder if the 1080 image is from a supersampled down 4k signal?  I doubt it but it would be nice.

Great review! Has there been an enhancement?

It can see almost the exact things you can see....
