Useful but Expensive

This beautiful small device can drive up to 2 groups of Speedlite flash units, and without cables. It is very light and comes in a small bag for protection. The ST-E2 is powered by a battery 2CR5 this holds for many trips, but I find it very unfortunate that no standard AA cells here (AA) or Micro cells (AAA) are used, of which there are also batteries. Sends an auxiliary light in low light as we know it from Speedlites to allow a focus. The device is actually almost a must when working with multiple Speedlites and also can be operated more easily and comfortably. Only at the price you should turn my mind yet, and the down - so one star less. With the newer Bodies like the 7D something is already integrated directly, which of course saves the purchase of this product.

What can possibly be to the detriment of one or the other here in the system is the thing which must exist for communicating a certain sight. I am currently working with the system, and if so flash2softbox a Speedlight is positioned slightly bad times behind a softbox (And bad ... the Lightning's usually behind the softbox = D), then it also does not ignite. As a wireless system is the reliability ago "probably" already mounted a little better.

ADDENDUM: In the meantime I have sold the ST-E2. The above-mentioned problem with the communication was me sometime annoying because the system simply does not work reliably in certain situations. I work now with a significantly lower radio system which although has no ETTL, but renders its service reliably, and can be combined beautifully with my studio flashes. ETTL the off-camera flash is like something Overrated in my opinion. Often I work manually with the flashes, to escape the ever-changing flash settings Ettl. And in case ETTL can be practical, easy a cable is used which is perfectly adequate for my purposes. (Wireless is indeed sometimes quite like overrated. * Hehe *)
