The SJCAM C400 takes a different approach to the action-camera market. Instead of simply shrinking down a conventional action camera, it combines a tiny detachable camera with a battery grip that doubles as a larger monitor and wireless controller. The result is a versatile setup aimed at casual vloggers, travelers, and everyday creators.
It records in 4K, features six-axis gyro stabilization, has a rotating touchscreen, and can deliver up to seven hours of claimed battery life with its grip. It also comes with a generous selection of mounting accessories. However, the C400 isn’t without compromises, particularly when you push it beyond casual shooting.
34K Video Is Good for Casual Shooting
The C400 records at up to 4K/30fps, with 2K/60fps and 1080p/120fps also available. It supports slow motion, timelapse, loop recording, pre-recording, motion detection and car recording.
In good daylight, the footage is sharp enough for travel videos, casual vlogging and social media. However, the 1/2.8-inch sensor means this isn’t a camera I’d pick primarily for challenging lighting conditions.
Low-light footage can look noisy and flat, while bright scenes can sometimes have blown-out highlights. Colors can also appear somewhat muted in certain situations.
The biggest specification limitation is the lack of 4K/60fps. If you’re recording fast-moving subjects, 4K/30fps doesn’t offer the same fluidity as higher-end action cameras. Slow motion is available at lower resolutions, with 2K supporting 60fps and 1080p reaching 120fps.
For casual creators, however, 4K/30fps should be sufficient for most everyday use.
