Sony has just released a new firmware update for one of their most popular bridge cameras on the market, the sony rx10 IV. This firmware update 2.00 adds real-time Eye AF for animals. Let’s take a closer look at it.
Sony RX10 IV Firmware Update
The Sony RX10 IV is a bridge camera that was released in 2017, and even to this day, it’s one of the most expensive cameras in its category. In short, it features a built-in Zeiss Vario-Sonnar T* 24-600mm F/2.4 – 4 x25x times zoom lens in front of a 1″ 20MP BSI CMOS Exmor R sensor. The camera can take stills in JPG/RAW at up to 24 frames, and the autofocus performance is some of the best available in a bridge camera: 0.03s AF speed and subject tracking that also works in video mode.
Talking about the video side, the sony rx10 IV can record in 4K UHD at up to 30 frames per second in XAVC S/AVCHD. Also, you can shoot in slow motion at up to 60 frames per second in FHD, and up to 1000 frames per second in 912 x 308. There is a micro HDMI port on the camera, microphone input, and headphone jack 3.5mm ports, and Wi-Fi/Bluetooth capabilities. To this day, the RX10 IV is still relevant if you are starting and want an all-in-one camera.
Nearly two years after its launch, the Sony RX10 IV just got better with firmware 2.00, that adds the following features:
- Adds real-time Eye AF for animals.
- Enables the possibility to operate the real-time EYE AF by half-pressing the shutter button.
- Improves the overall stability of the camera.
Real-time Eye AF for animals is a feature that is already available on the Sony a7R III and a7 III full-frame mirrorless cameras. It is nice to see that Sony is adding this feature to more “consumer” cameras.
