I'm camera-toting journalists. Just as my camera (Canon 7D) and the flash unit must meet a whole spectrum of tasks. This ranges from the Fill-in the summer sun, goes beyond the brightening of the night accident scenes and ends with the typical lightning task in enclosed spaces. The Metz MB 58 AF-2 can be quickly attach to the camera and provides wonderful illuminated images. The two reflector is a real additional profit. The sometimes criticized rest time for me no problem. All in all a very good device. The only downside: Setting the flash functions might be a bit easier. Especially when it is in a hurry and there is no time, it's easier on the camera to close the aperture or to devalue the ASA value.
