Hi,

I just bought a Beachtek DXA-SLR PRO to use with some Canons (6D, MarkII or MarkIII). I have yet to receive it but I was looking at the pictures and wondering if the battery compartment is accessible as the camera is place on the Beachtek. It´s not very practical to take the camera out of the beachtek whenever you want to replace a battery. Plus I was thikning about getting a DR-E6 DC and but I´m not sure it will fit with the Canon mounted on the Beachtek

If you mount a dSLR camera directly on the BeachTek in the "correct" position, then no you can't change the camera battery without separating the two devices. However, since the BeachTek has a very large wheel to tighten and loosen the connection (which is accessible from both the front and back of the device so you can use two fingers or even two hands to start the loosening process if the setup is mounted on a tripod), it's easy to do this separation.
If you're in a very stable fixed position with a tripod, you can mount the camera at right angles on the BeachTek (the BeachTek is aligned with the lens). This allows someone from the side to adjust the BeachTek controls and you can change the camera battery without separating the two devices. I wouldn't recommend mounting it this way for active shooting situations though, there is much less physical support when mounted at right angles.

A battery grip is the best way to deal with this... Double the battery life, and the battery tray slides out through the side so you'll never have to take it apart.

That is an excelent and very simple idea :)

Here's the one I use, it's a little cheaper than the Canon version and it works perfectly.
Mine stays attached to the camera at all times...

Mine would be for the 6D, so I guess this one would do the trick: XIT XTCG6D Pro Series Battery Grip for Canon 6D DSLR XTCG6D B&H
