Unless otherwise stated, all figures assume a fully-charged battery and an ambient temperature of 23 ±3°C (73.4±5.4°F) as specified by the Camera and Imaging Products Association (CIPA). JIS/IEC protection class 8 (IPX8) equivalent (under our testing conditions) Capacity to record images and movies underwater up to a depth of 10 m (33 ft) and for 60 minutes

1. Battery life does not reflect the use of SnapBridge and may vary with the conditions of use, including temperature, the interval between shots, and the length of time that menus and images are displayed.

2. The remaining movie recording time (the amount of time that can be recorded for an individual movie) displayed at the top of the shooting screen depends on the remaining amount of space on the memory card. Recording may end before this limit is reached if the camera temperature becomes elevated.

3. When the battery temperature is 0°C (32°F) or lower, movies with the size/frame rate set to 2160/30p (4K UHD) or 2160/25p (4K UHD) cannot be recorded.
• If the battery temperature is 0°C (32°F) or lower before you start recording, the size/frame rate of the movie switches to 1080/30p or 1080/25p.
• If the size/frame rate of the movie is set to 2160/30p or 2160/25p and the battery temperature drops to 0°C (32°F) or lower while recording, the camera stops recording and automatically turns off. The recorded movie is saved.

4. Dropped from a height of 200 cm (6 ft 6 in.) onto a surface of 5 cm (2 in.) thick plywood (changes in appearance, such as paint peeling off and deformation of the drop shock portion and waterproof performance are not subject to the test). These tests do not guarantee that the camera will be free from damage or trouble under all conditions.
