New Flash Triggers - Flash Stuff...
Canon users who want to use their 430EX II and 580EX II flashes off camera have a new bit of gear to help them. Hahnel have released their Tuff TTL wireless flash triggers to let you do this easily.
You'll already have seen the Hahnel wireless trigger kits that operate in direct mode - they can shoot over 100 metres with a convenient Canon-fitting hotshoe on the top and a 1/4" screw socket on the bottom. No TTL with that one, but it could be used in one configuration to fire the flash, and in another to fire the camera.
Now the Hahnel people have the TTL version - it is housed in a re-enforced case with rubber covering. There is provision for full TTL operation with Canon flashes and you can command high speed synch, flash compensation, and second-curtain synch right from the transmitter. Range is still 100 metres but in this case they do not intend it to be used to be a remote trigger for the camera.
Best of all, it does not need fenocky batteries to operate - both transmitter and receiver run on standard AA cells.
The set in store right now for $ 149. Extra receivers available for $ 95each.
