What also should be mentioned: Nikon has a whole bunch of cameras that are compatible with this little thing. I'm thinking a: D40, D40x, D60, D3000, D5000, the high-end compact P7000 (2 receiver: front and back) as well as the new D7000 and the brand new D5100. The latter two have also on the front and back each have a receiver. I would like to reward you with a 5 Star: this consequence is exemplary.
(Unfortunately, a little bitter aftertaste: the new D3100 also has no receivers, here you benötig now a Kabelfernauslöser ...)
A little tip: If you like me "to security" but then wants to have a spare battery or suddenly on vacation, far away from the Amazon, one needed: in branches of Dt. Post (at the office stuff) and at the drug store Rossmann (usually the checkout area) which I have discovered, for little money. One should pay close attention to the type, with the same scope, there are about 4 different types of battery, but differing by the thickness.
