For a month now I use the battery grip and could not fault it.
The processing can be classified as valuable and very good, nothing rattles, shakes or looks "inferior" from, it fits perfectly,
The handling has improved a lot, now succeed even easier vertical shooting, the controls sit well and can be switched separately
will prevent accidental trigger to.
The batteries are almost uncanny to me, I unpacked it and reingesteckt and the cam still shows me always
full battery, even though I often work with Live View and Long Exposure, which now for over a month ...
The IR remote release does the job, although he only, and really "ONLY" work when it is directed from the front straight at the camera,
he responds mE also somewhat sluggish, often I have not used it, he was just there ...
In short; The battery grip fits and is an absolute recommendation.
Note would be the enlargement of the bodysuits by about half the height of the camera and the still noticeable extra weight.
At my 600D looks all really professional, because people look twice towards what "of as" thick in
the hand holds.
In general I feel the extra weight not as annoying, the whole is now "tired" in his hand.
I always have to laugh when people buy a DSLR with the make believe just so "good" images,
at the latest after the first hike etc they whine because weight undso ...
