Some recessions has been described, it is a cumbersome always unscrew the battery grip to gain access to the battery in the camera. So I use the battery grip with no battery in the camera, because I do not want every time unscrew the handle to gain access to the battery in the camera.
Furthermore, it was also described, which manage other manufacturers to incorporate two batteries in the handle. Ok that may be, but that does not bother me much. Since before I charge two battery packs must, it's no problem for me to take out the slide on the handle and insert the new battery.
As everyone knows, the battery lasts very very long, that's why for me one of the most unimportant things that have been mentioned here by others.
Say In addition, even a slide for six batteries included, so as a last resort for the way, just in case run out of juice. It can also be operated in six batteries him, so plenty of opportunities for holidays and the like.
Processing of the battery grip's is excellent, the gum is identical to the camera. Also, the housing of the handle is identical to that of the camera. If one did not know better, one would think the camera has been built so everything fits together very well.
The battery grip has another a switch to on or off the handle, for accidental adjustment of the diaphragm or the like.
My Conclusion:
I can issue a strong buy recommendation with a clear conscience.
For price, he is proud but worth every Euro.
Those who already At length an expensive camera, should not save at the wrong end, is my opinion. (Counts in the battery)
With best regards
