The FLEX DSLR Remote from Switronix is a patent-pending, handle-mounted DSLR remote that triggers HD video start and stop recording for Canon 5D & 7D cameras. The FLEX's unique gooseneck arm houses an optic that is to be positioned within line of sight to the remote sensor on the camera (transmits up to 3.28' (1 m) away, 135° coverage). Once positioned, the remote transmits a signal through the optic when the button is depressed. The arm can be extended up to 12" (30.5 cm) and coils down to approximately 3" (7.6cm) in diameter. The FLEX's all metal construction will stand up to the everyday rigors of HD DSLR video production and is powered by 2 AAA batteries (included).
