Radio Triggers
Hi
I'm looking at buying a radio trigger for my canon 7d to work with a 420ex and 550ex are there any cheaper models out there that will work with high speed sync mode other than the very expensive Pocket Wizards? Loads of cheap options on ebay but all seem to have a max sync speed of 1/250 or 1/500. I'd like to use them at high shutter speeds in day light with the lens wide open. Any ideas?
Cheers
