I'm much more active in the event area and have been here to test the benefits extensively! and I must say it works beautifully!
the location of the first test so you have to imagine (large beer tent with black trim inside)!
So the ST-E2 up to the 1D Mark III and the Speedlite 430 EX 2 erected or held in the hand!
Any trip without problems carried out even if it has been thought that goes not only because only bad was sight!
even if the price is relatively expensive and also the batteries cost a lot (here on Amazon cheap compared to commercially available) I regret the investment sometimes at any time and look forward if I can still shoot a lot more photos won the freedom!
