How do you focus your Nikon D5000 camera when filming?
If you have an AF, or auto-focus lens (like the kit 18-55mm lens) you can focus your lens prior to filming, but cannot auto-focus while filming. To manually focus, switch the switch on the side of your lens to 'M' for manual. To focus, turn the outer focus ring on the lens until your subject matter is clear.

The lens in the human eye is a convex lens, but it is flexible and when it is acted on by the ciliary muscle around it, the lens can be "flattened" to change the focus, or, when the muscle is relaxed, the lens can assume a more spherical shape. This is at the heart of the ability of the eye to focus on objects nearer or farther away.
