The Scott Kelby Mitros+ TTL Flash and Odin TCU TTL Flash Trigger Kit for Canon from Phottix features the Mitros+ TTL flash for Canon, the Odin TCU TTL flash trigger, 10" flash softbox with strap, a 36" Double-Small white shoot-through umbrella, Varos II multi-function flash shoe umbrella holder, a 6. 6 pound Stay-Put Sandbag II, a 28" gear bag, and a 6. 5' 5-section compact light stand. This gives you a wide variety of tools and accessories for advanced off-camera flash photography. The basis of this kit is the Mitros+ flash, which has a guide number of 190' at ISO 100 and 105mm and a built-in Odin transmitter/receiver. This works well with the Odin TCU flash trigger for remote flash control and firing. They work within 4 channels and 3 groups within a range of 328' with a 2. 4 GHz frequency. These are specific to Canon cameras with E-TTL / E-TTL II. The 10" softbox and strap lets you diffuse the light of your shoe-mount flash unit. It even has movable inner diffusers for more control and a top vent for bouncing light. There is also a Varos II Multi-Function umbrella holder for mounting a flash to a stand and utilizing the included 36" Double-Small folding white shoot-through umbrella. Additionally, there is a 5-section 6. 5' light stand, a 28" gear bag, and a 6. 6 pound Stay-Put II sandbag.
