Any .46 will pull it fine and a small light camera will hardly be noticed as far as weight goes.

Just be sure to use foam to mount the camera or rubber band suspension would be even better. If you don't, the pics will be blurry from vibs. Dropping to idle before snapping the shot works too sometimes.
I made a mount for the camera with a flex push-rod to push the button then used RB's to hold the mount. Worked great!
