After years of waiting Sony has finally released its third edition of the A7s series. It is essentially a native 4k camera with impressive video specs and a revised user interface. It can capture 4k at upto 120 fps in 10 bit 4:2:2 encoding and promises 16-bit Raw video output.

Instead of chasing headlines, Sony has worked on giving filmmakers a camera they need, with lots of codec choices without limits on frame rates.
- 12MP Full-Frame Exmor R BSI CMOS Sensor
- On Sensor Phase detection
- ISO 80-102,400 (expandable to 40-409,600)
- Fully articulating 3 inch LED touchscreen
- UHD 4K 120p Video, 10-Bit 4:2:2 Internal
- 1080p at 240 fps
- 16-Bit Raw Video output at upto 60p
- 5 axis in body stabilization with Steady shot active mode
The camera also boasts of shooting 240fps at 1080p but the only way to get it is to use the camera in HD S&Q mode which means it doesnt record audio.

It can be used to rack focus smoothly and organically, depending on the AF focus settings. The speed of focus can be adjusted over seven increments from fast to slow, and the transition speed in five steps. With great focus tracking, helped by touch-to-focus on the screen which then tracks the object as it moves, its Sony’s best yet.
If your work is predominantly video in 4k or HD then this is the camera that will suit your needs. And thats what most film makers want from their camera right now. Sony A7s mark 3 is now available for rentals with Paxton Equipments.
