After only 2.5 years can be at once the internal flash of my Canon 500D no longer leave (have the camera treated really well and that is according to Board reports occur more frequently). According to Canon, the device must be repaired. Since I have neither the desire nor the time to repair my otherwise so estimated camera for a lot of money, I had to buy an external flash the idea. Thus, I was looking for a low-priced, small and light, "always on it" flash. The fairly good reviews led me to this small Metz flash. What can I say? I'm happy again !!! The lightning strikes the internal order lengths and in rooms I will now only indirectly flashes (at normal ceiling height). If this time but should be a bit too low exposure, can the awesome Burn in RAW format. Definitely better than this terribly overexposed photos for a ton. Also awesome that I now with my long 70-200 Canon zoom lens can make photos in rooms without a lens shadow. Certainly there is much more powerful models. But certainly not in this price range. This flash unit does just joy and you can easily with good results always have (easy, especially since only 2 batteries). ... PS: By the way, I do not get commission from Metz :-)
