Sony A7S III (Body Only)
Get Rewarded with Sony's $50 Cashback Campaign! More details below.
Product Overview
The Sony A7S III is a fantastic full-frame mirrorless camera body, and it especially excels when it comes to video. Low light performance is incredible. Being able to shoot at ISO 409,600 means you can shoot in almost total darkness. It can also shoot 4k video up to 120fps. The camera's autofocus system is also lightning quick with its 759 phase-detection points along with 425 contrast-detection areas; it's not only fast but also accurate.
The optical quality of the Sony A7SIII is second to none; it can capture tack-sharp details helping you produce stunning photos and videos! As this camera is primarily targeted towards video shooters, Sony has consciously avoided packing it with a high pixel count, instead opting for just enough so it can shoot 4K quality footage. By doing this, they have massively reduced the risk of rolling shutter.
You can get crisp 4K footage, and pin-sharp still images with more than enough detail to satisfy even the keenest amateur or most demanding professional but without the rolling shutter. This is one of Sony's most popular cameras and for very good reason. If you have any questions about the A7S III, please reach out to the experts here at Bluewater Photo; we're always happy to help.
