There have been many improvements in the compact camera lines over the past few years. Larger sensors, faster focusing, and more controls have all led to a selection of cameras that work smoothly, keep size tiny and are functional with a variety of lenses and accessories to round out your underwater photography experience. Sony and Canon have both given their compact cameras one inch sensors, and greatly improved focus speeds over the cameras of a few years ago. Olympus continued to add features to their cameras while keeping both price and size down.

So what makes a good underwater camera? In addition to image and video quality, there are several other important factors to consider, like the overall quality of the camera's optics, including zoom range and maximum aperture. The latter is crucial for low-light photography, as larger aperture typically results in better photos since it allows more light in. It also minimizes motion blur, making larger apertures perfect for action shots. (Note: The smaller the number, the larger the aperture.)
Another highly sought-after, and relatively exclusive, feature within the video camera realm is the ability to record in RAW or ProRes. These are uncompressed formats that maximize the information gathered by the sensor and provide you with extended flexibility when it comes to color grading and post-processing. As mentioned, this feature is quite an exclusive one and only available in a select few cameras on the market with good processors (again, excluding high-end cinema systems). Some select cameras can record in ProRes Raw with an Atomos Ninja V external recorder. Nauticam offers a housing for the Ninja V for use with your underwater system.
