Annoyed me the internal flash of my Canon 500D extreme, because he is sau slow and quite modest. However, I did not want to spend enormous sum for a professional flash, because I feel more to the fun, as the seriousness of the matter. This flash Metz is easy saugenial for its very small budget and helps incredibly well in low light, if you like the color of a flash, which is not always to meet with me. For the investment, he works really well and is sufficient for quick and bright. As for the Battierie hunger I can only judge positively. Who does not want expensive shopping gets here really a lot for the money.
