No serious camera today should be without a swivel (or at the very least a tiltable) LCD, which makes it more convenient to take pictures. And yet many cameras lack such a LCD. Swivi wants to rectify this situation with the Swivi External Swivel LCD Monitor which attaches to your existing camera tripod mount and connects to your camera via its HDMI output. It is powered by an included AAA battery adapter and provides Peaking Focus, Zoom In and Zoom Out functions and built-in stereo speakers.
