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.
