The Vello FreeWave Viewer VL Wireless Live View Remote Kit with AV/Shutter Cable for Select Canon Cameras from B&H is a transmitter and 3.5" monitor kit that includes a FreeWave Viewer VL Data Cable designed for use with the Canon 20D, 30D, 40D, and 50D for attaching the transmitter to the camera for proper operation. This system allows for wireless viewing and remote shutter triggering of your compatible DSLR camera.
The Vello FreeWave Viewer VL Wireless Live View Remote consists of a 2.4GHz radio transmitter, and a monitor receiver with a 3.5" Live View TFT-LCD screen. Together, the transmitter and receiver provide a wireless viewing system that enables remote shutter control from a distance of up to 328'/100m.
The live view monitor features a 3.5" display with a 320 x 240 resolution that is able to provide a view of what your camera is seeing. A removable pop-up shade allows for improved viewing when shooting in direct sunlight or brightly lit situations. The monitor's design integrates a remote shutter release button that supports half-press control for pre-focusing. A dedicated button allows switching between AV (live view) and CCTV modes for different perspectives of monitoring, and a channel switch button permits changing between different transmitter channels. A 1/4"-20 tripod mount is located on the bottom of the unit for hands free viewing. Both the brightness and contrast of the display can be manually controlled.
The transmitter can be attached to the camera via its hot shoe, and connects to the camera using the included Y-cable. The AV connection provides the live view signal for remote viewing on the monitor, and the shutter release connection allows for wirelessly triggering the shutter from the monitor. A CCTV camera is integrated into the transmitter's design and incorporates a 45mm lens (35mm equivalent focal length) to provide another perspective for viewing subjects in front of the camera. The CCTV camera is especially useful to monitor when a moving subject is about to enter the frame for situations when you're using a telephoto or long lens to photograph. Additionally this camera's functionality is ideal for use when the connected camera does not support live view or if trying to conserve the camera's battery life for extended viewing sessions. The 2.4GHz radio transmitter has four selectable channels for greater control when more than one unit is being used within 328' proximity.
