Caveats
- Waterproof figures on the spec table appear swapped/garbled ('16ft with waterproof case / 131ft with protective frame'); marketing text says 16 ft with protective frame and 130 ft with waterproof case.Source
- Listed weight 370 g likely includes the battery grip/accessories; bare camera weight not stated.Source
- Both sensors are only 1/2.8-inch per SJCAM's SJ30 comparison; 20MP stills are a maker claim.Source
- Exact announcement date not found; SJCAM blog of 2023-11-07 calls it 'newly launched'.Source
