Compact imaging technology is developing rapidly. Small cameras now feature large sensors capable of capturing high-quality images and HD video, while still fitting snugly in your BCD pocket. Here are nine models above that will empower you to take your underwater photography and video to the next level — and four trends to consider before making upgrading your system.

TREND 1: Big Sensor, Little Camera (Backscatter Canon S100 Powershot Package - Editor’s Pick)

Small cameras are now capable of big things, as image quality improves while body size and weight decrease.

TREND 2: The Video Revolution (Go Pro)

Not only can small, pocket-sized cameras now take high resolutions stills, they can also shoot beautiful, cinema-quality HD video.

TREND 3: Keeping It Simple (SeaLife DC1400 Pro)

Not into all the technical jargon and fancy controls? Menu systems are becoming simpler, allowing for easy navigation of advanced features.

TREND 4: Small and Rugged (SEA & SEA DX-GE-5)

Cameras are being built to withstand extreme conditions — some are waterproof, freezeproof, and even crushproof, without a housing.
