Centering objects?

Is there a quick way of centering objects in the camera view mode?

You can select the camera frame in camera view and then grab mode. This will move the camera for centering.

Or you can rotate / pan your 3D view to the alignment you want and then “SHIFT + KEYPAD 0” to place the camera in that viewing position.
