For the price you get a flash of the original system (in my case, that would be a Nikon flash) can compete, yes even surmounted with the services!
A plus I give for the handling (the head can easily rotate in all directions), the metal foot, accessories such as the Stand (to use also for tripod) and the bag, the menu (which is perhaps getting used to at first) and the general services.
Optionally, a battery is plugged in, and via USB can be uploaded later updates (which was already given in AF 48)
Also master-slave is not a problem, and with the AF 58 as a master I can drive 48 AF successful (because my camera does not support this, unfortunately).
A high-light is of course the small external flash forward, one can leave "mitblitzen" with different performance levels.
The only, but until now only only downside is that the menu is a little slow. If you quickly want to "surf" through the menu and just knows where the functions are, you have to apply a little patience. Not really tragic, but if it should go something quickly, this could prevent something.
But what do you want more: German quality (I hope times) for a very correct price!
Therefore I can only recommend this flash.
