I had to flash for some time on a Nikon D40x and was not very happy with the results. Certainly the flash is much better than the built-in flash, which already let alone suspect the specifications. To really useful to flash indirectly the flash in my opinion, but suitable only very limited because the relatively weak guide number of 30 at the flashes on the ceiling is only suitable for normal Aufnahem standing and at normal room heights. The distance to the object should not be too large. Otherwise, the flash output is simply too weak, for example, in higher areas or pictures of children near the ground.
But: The flash is really very compact and is quickly mounted, if it is always on it it does not interfere even when slung over her camera on. The adjustment of the reflector is also good.
Conclusion: Beautiful and well processed compact flash, but for what he does too expensive. In this price range there are better Aufsteckblitze with much more power that are not so nice and small, however.
