"Introduced at Photokina 2014, there is no flash triggering system that is more anticipated than the Odin II. It is the result of operational requests from the thousands of happy Odin users who love their TTL flash systems and want even more. Phottix is delivering on all of its promises. And then some. Unrivalled Control and Streamlined User Interface The Odin II gives photographers more control than they have ever experienced; control that is direct, logical and fast. Each of the 5 Groups has its own quick-access button. Changes are made by turning a large, perfectly-placed, control dial. Pick the light. Make the change. Lock it in. Shoot. A large, illuminated LCD panel shows all settings at a glance. Control five lights or groups of lights, in TTL Auto or Manual. Switch a Group OFF and its display line disappears from the screen. Displaying only active groups assures an easier and simpler viewing experience. 5 groups A, B, C, D, E 32 channels with User-set Digital ID Group buttons and control dial for fast changes TTL Power Control +/- 3EV Manual Power Control 1/1 to 1/128 High Speed Sync - up to 1/8000s Second Curtain Sync (Nikon, Sony only) AF Assist Light Flash Zoom control Modeling Light Control with Indra500/360 2.4 GHz, Range 332ft (100m) Compatible with Indra500/360 TTL, Mitros+, Odin, Strato, Strato II, Atlas II Firmware upgradable More Channels and Digi"
