SJCAM SJ4000 Pro-Grade 4K Action Camera - Stabilized Waterproof

In this review the SJCAM SJ4000 is presented as an entry-level action camera that punches above its price class thanks to built-in gyro EIS stabilization, a 170 super wide angle lens and an extensive accessory kit. The bottom line: it is best for hobbyists, motorcyclists and divers who want solid 4K 30fps video, long run times from dual batteries and plenty of mounts without paying premium camera prices.

Key Features

• 4K 30fps video: Records crisp 4K 30fps video for high-resolution clips suitable for social uploads and cropping.
• 40MP photos: Shoots up to 40MP stills so you can extract detailed frames from action footage.
• 3-axis EIS stabilization: Built-in gyro stabilization reduces shake during rides and active sports for smoother footage.
• Waterproof to 98 ft: IP68-rated case enables underwater mode for diving and clear recordings at depths to 30 m.
• Accessories and power: Includes two 900mAh batteries and a kit of mounts so you can shoot longer and attach the camera to helmets, bikes and more.
• Ultra wide and zoom: 170FOV plus a 1.0X to 5.0X zoom gives flexible framing for landscapes and close-ups (note FOV must be turned off when using zoom).

Who It's For

The SJ4000 suits hobbyist shooters, motorcyclists and vacation divers who want a budget-friendly action camera with a full accessory package and decent stabilization. The combination of wifi, two batteries and included 32GB SD card makes it a ready-to-shoot option for outdoor adventures and helmet mounting.

Those who need professional audio, flawless in-camera stabilization every time, or the absolute highest dynamic range should look at higher-end action cameras; customers reported mixed results with the EIS feature and noted that sound quality is not a strong point.
