The only part of the review that is faulty is the discussion of the shutter button. The purpose of the half press in higher quality cameras is to freeze the aperture and focus so the photographer can reframe the shot keeping the same initial settings.

To demonstrate, try this... Center your camera on a bright area and half press. While holding the half press move the camera to a much less bright area. Now release the half press and notice how the aperture now adjusts to the change in brightness. This allows a photographer to have control of how lighting effects his image. The half press works the same way for focusing.

A real shutter button with a functional half press is an absolute necessity for a photographer who knows how to use it. All pro quality camera shutter buttons work this way.
