And there he is now. The grip he is noticeably better than that of the other handle, it is very soft and comfortable to hold. In my long fingers I sometimes come to the locking wheel. That's about unfamiliar, but does not interfere further.
The trigger is applied very delicately, smallest touches rich already at a picture to shoot (and on the D300 that is usually: focusing and shooting in the fraction of a second). That's actually very pleasant to get a little messed up if you frequently turn the camera: Somehow no longer wants to feel really broken the main trigger.
It also happened to me also like that I now in horizontal position with the palm shoot photos because I have the button again unlocked - Care in the camera bag, otherwise both batteries are down fast!
The "joystick", which takes over the function of Wippknopfes works wonderfully, there but I could discover no compromising on Nonameprodukt.
In sum, I can say that one such a handle, not necessarily for photographing in "portrait" orientation needs - but if you have it, it's a completely different feeling. From me there is a buy rating. The price is high, but that you know what you have and get the full support.
