The Chinese manufacturer Bosma has developed a compact 8K camera with MFT mount, which is distributed by the Japanese company Astro Design. It is aimed specifically at broadcast and surveillance tasks and can therefore stream its images live via network.
The Astro Design BOSMA G1 8K Micro 4/3 camera weighs only 1.25kg and uses a 33 megapixel CMOS sensor measuring 18.84 x 10.60mm (which is roughly the same as the Panasonic GH5 MFT camera) with a resolution of 8K (7,680 x 4,320 sensel). It records 8K video at 30/25/24 fps and 4K at 60/50/30/25/24 fps to CFast 2.0 cards or via USB 3.0 of an external SSD.

The video can also be output via HDMI and recorded using an external recorder - to output 8K the latest HDMI version 2.1 is used.
8K is recorded with a maximum bitrate of 200 Mbit/s, 4K with a maximum bitrate of 100 Mbit/s - compressed either by H.264 or H.265 (VBR/CBR) as .MOV or .MP4 files. The Astro Design BOSMA G1 8K supports the IPv4, RTP, RTSP and SRT streaming protocols and can thus stream its videos live to the network via its Ethernet connection or WLAN. The lens can be remotely controlled via network as well as other functions. The Bosma 8K draws its power either from the mains via its DC 12V 5A (4-pin LEMO) input or from a Sony NP-F series battery.
It is suspected that the 8K sensor is the one developed by Sharp in collaboration with Foxconn for its 8K MFT camera, which was first introduced in 2019, as Astro Design has cooperated with Sharp many times before.
The same objections we made to the Sharp 8K MFT camera apply to the Bosma 8K MFT camera: at 8K resolution, the edge length of a sensor is just 2.25 µm. These days, you can only find pixels that small in smartphone cameras or consumer camcorders with sensors under one inch. This narrow sensor structure leads to severe limitations in light intensity and dynamic range.
Astro Design has not yet officially announced the price of the Bosma G1 8K.
