Announced over a year ago at CES 2012, Phottix has priced and released their Mitros TTL Speedlight for Canon cameras today, with the Nikon and Sony versions coming in May. It's priced at $349 MSRP, but I expect to see it from dealers for around $300.
Phottix has been working diligently to make the Mitros as perfect as possible, as you can probably imagine from the very lengthy wait between announcement and release. Phottix claims the Mitros will do everything you expect a top-of-the-line TTL flash to do. Its functions include built-in IR triggering with Master and Slave modes, AF assist light, auto/manual zooming flash head and all with fast recharge times. The Phottix Mitros TTL Flash includes a USB port for firmware upgrades and a 3.5mm Sync port.
The Phottix Mitros is pretty powerful with a guide number of 58. The flash features full TTL functionality as well as manual and multi modes. It is the perfect compliment to the Phottix Odin TTL Flash Trigger system as well as fully compatible as a master or slave with Canon's native IR (no, not radio) system. The Mitros also features an optical slave mode.
