Review Excerpt

  • Good image and video quality for a compact waterproof camera; Stylish, pocketable design; Improved ruggedness; Speedy performance including 10 fps continuous shooting at full resolution.

  • Touchscreen unusable and unviewable while submerged; Slim, slick design makes it unwieldy to hold (and difficult to hang onto!) underwater; Poor battery life.
