I have no idea about the battery in the WFT powering the camera, but I doubt it as from the pictures it doesn't have the pillar that goes in the battery housing to power the camera, it seems to only connect through the terminal block on the bottom of the body. The power supply should be ok to use with the WFT grip as the cord comes out through the side of battery housing.
I have some questions for this grip that I can't seem to find the answers for.
1) does the battery in the grip power the camera as well, and I won't need a battery in the camera?
2) if not, can the ac adapter ack-e6 be used on the camera with the grip on, so I don't have unmount the grip to change batteries every time?
Hope you guys can help
