A:
I can't give you a simple yes or no since I don't know the exact weight of the camera or the lens you are using it with.
My camera weighs a pound without the lens, and my 80-300 equiv. lens about the same. If your setup is much heavier I'd be careful, and I wouldn't use a very long, heavy lens unless there is a tripod mount on the lens. Also, be careful to support the camera when making tilt adjustments.
