The Phottix Mitros+ is a groundbreaking new product - a third-party TTL flash with built-in radio triggering and power control functions. Currently available in a Canon ETTL compliant version, Phottix Mitros+ flashes can be remotely controlled and fired with a hotshoe-mounted Mitros+ unit or one of many compatible Phottix flash triggers. Unlike optical or infrared flash syncing solutions, radio triggering does not require direct line of sight and tends to work well indoors and out, at night and in broad daylight, over relatively long distances. The Mitros+ offers all of these triggering modes plus a 3.5mm sync port. As to basic flash functionality, the Phottix Mitros+ has a guide number of 58 (in metres), high-speed and second-curtain synchronisation modes, a zoomable tilt-swivel flash head with 24-105mm coverage (14mm with a wide-angle diffuser), an AF assist light and a quick flash mode. Three sets of flash and function information can be saved in the Mitros+’s memory and be quickly recalled when needed. The Mitros+ TTL Transceiver Flash for Canon will start to ship during October 2013. The price has not been announced yet but we expect the Mitros+ to be more affordable than its closest competitor, Canon's own Speedlite 600EX-RT. The Nikon version is expected to be released by the end of 2013.
