So I umgeguckt me here and read in DSLR forums. Ok 50 EUR is not so much money, so just try it. Ware was shipped super fast of "my photo Berlin" and the handle is class!
+ The grip is better than the original handle, since an additional vault below the index finger is present
+ The price is less than half (!!!) of the original
+ Functions as the original
The only (teeny) difference from the original product in that the symbols (AV, etc.) are printed on the buttons not quite scharfkantik. There you can see a replica of "Made in China" ... Otherwise: highly recommended!
