Strengths and drawbacks
SJCAM SJ11 Active
- +5 m of bare waterproofing, which several pricier budget cameras do not offer
- +Dual screens make framing to camera possible
- +A Sony sensor and an Ambarella processor, both named by SJCAM
- +GoPro folding fingers rather than a proprietary shoe
- −Joint-smallest sensor in the catalogue at roughly 18 mm²
- −No horizon lock, and 4K caps at 30 fps
- −5 m bare covers a pool or a snorkel; anything deeper needs the case
SJCAM C300
- +Six hours of 4K30 recording with the grip is a genuine all-day figure
- +Pocket format clips to a pocket or lapel where a GoPro shape will not
- +Dual screens at $159
- +Six-axis gyro stabilisation rather than software-only smoothing
- −No bare waterproofing; the case is required
- −4K30 only and no horizon lock
- −The body shape does not suit helmet or handlebar mounting
- −SJCAM publishes no weight or bitrate for it
