Works Great


from Waxahachie, texas  -  Semi-Professional

Works as described. I had been wanting an off camera flash trigger that was compatible with high sync and rear curtain flash but the few that were out there were expensive. These work great at a 1/3 of the cost.


Does what it is supposed to do!


from columbus OH  -  Semi-Professional

Excellent value. Communicates well with my Canon gear. Great control over distance. Would buy more Phottix products based on my experience with this unit. Well made, comes with a full range of cables and an excellent case.


Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  I'm not sure why they got rid of the hotshoe on the trigger. I mostly use these triggers while a flash is mounted to my 5d3 for focus assist/fill. Will the USB port on these trigger the flashes fine? If so I might just velcro it onto my flash.
Shopper  Is it set up for the Canon 7D on Phottix Strato Web site it has 4 pictures from a 7D?
Andrew R  I believe that this unit is compatible with most of the Canon EOS system DSLRs (though the manufacturer's info isn't very clear). It also has a feature that provides optimization with the 1DX.
