Bosma Bosma G1 Pro 8K Camera (MFT) Review
The Bosma G1 Pro shoots incredible 8K video, but it demands you do all the work. Here's who should buy it and who should run for the hills.
The 30-Second Version
A powerful 8K video module that forgets how to be a camera. Fantastic output if you manually focus and stabilize everything yourself.
Overview
The Bosma G1 Pro is a camera that asks one simple question: do you need 8K right now? If you're a filmmaker who demands the absolute highest resolution for reframing or future-proofing projects, this is a surprisingly compact and capable tool. But if you're looking for a versatile daily shooter, this isn't it. It's a specialist, laser-focused on delivering a high-end video signal with a ton of connectivity options, wrapped in a body that feels more like a cinema module than a traditional camera.
Performance
The video performance is, unsurprisingly, its standout feature. It scores in the 97th percentile for video quality, which means it's among the best on the market for pure output. The 11 stops of dynamic range and the ability to shoot 8K30p at 600 Mb/s are serious specs. What surprised us, given its cinema ambitions, was the middling score for autofocus (43rd percentile) and the lack of any built-in stabilization (41st percentile). This camera assumes you're using manual focus primes on a tripod or gimbal. The sensor itself is solid (78th percentile), but the overall 'build' score (81st percentile) suggests it's well-made but not in the ultra-rugged tier.

Value & Pricing
Prices swing wildly from $3499 to $4862. That's a $1363 spread, so shop carefully. At the lower end, it's a compelling value for the raw video power you get. At the high end, it starts bumping against more established names. Worth it only if 8K is a non-negotiable requirement for your work today.
vs Competition
Against a Sony A1 or Canon R6, the Bosma loses badly in versatility. Those are hybrid cameras with world-class autofocus and stabilization. The Bosma beats them in pure 8K video output and pro connectivity. Against a dedicated cinema camera like a Panasonic GH7, the fight is closer. The GH7 will have better overall handling and a more polished ecosystem, but the Bosma's 8K specs and Ethernet/data control might edge it out for certain studio or live-stream setups. It's a niche pick.

Common Questions
Q: What is this thing actually for?
It's a dedicated video camera, best suited for controlled filming environments like studios or scripted shoots where you need the highest resolution.
Q: Can I use my Panasonic or Olympus lenses with it?
Yes, the MFT mount means native Micro Four Thirds lenses will work. But be prepared to focus and adjust aperture manually—autofocus communication seems limited.
Q: What's the sensor crop factor?
It's a Micro Four Thirds sensor, so the crop factor is 2x. A 50mm lens will give you a field of view equivalent to a 100mm lens on a full-frame camera.
Who Should Skip This
If you're looking for an all-around camera to shoot both video and photos, skip this. Its stills capabilities are weak, and it has no autofocus or stabilization. Go get a Sony A1 or Canon R6 instead.
Verdict
We recommend the Bosma G1 Pro only for a very specific user: the independent filmmaker or studio that needs a compact, 8K-capable video capture module with robust streaming and data features. It's not a camera you'll take hiking. It's a tool you'll bolt onto a rig. If that's your use case, it's a strong option. For everyone else, look at the hybrids.
