Astro Design’s new 8K camera solutions – Newsshooter



Astro Design has been making 8K cameras for a long time. We have covered quite a few of them previously on the site. Well, now they have an 8K 120p/60p Live Transmission System that is based around the AB-4815 camera. This camera is not new and it has been around since mid last year.

Astro Design also has a new 8K 60p camera called the AB-4831 which features a global shutter. The third 8K camera is an S35mm global shutter multi-purpose box-style camera that features an M4/3 mount.

These cameras have all been designed for live 8K transmission and outside broadcast applications. Japanese national broadcaster NHK has been using Astro Design cameras for quite some time and plenty of their cameras will be used to cover the 2020 Olympics if they go ahead this year.

The AB-4831 is an 8K 60Hz camera that features a Super 35mm CMOS Sensor (24.576mm×13.824mm) with a global shutter.

8K video at up to 60p can be output in real-time through four 12G-SDI outputs for use in live events such as stage performances and sports matches. Just like Canon’s prototype solution that we recently featured on the site, the AB-4831 has not been designed for 8K internal recording. This is a camera that has been specifically designed to be able to output 8K for live broadcasts.

The camera can be controlled externally by connecting a remote controller (RB-4816-2). It features a PL mount and Astro Design claims it has 11 stops of dynamic range.
