Firmware updates are coded instructions that can be written into the program memory chips of the camera itself. These updates are normally limited in scope, and improve or correct how the camera performs certain functions. They do not change the specifications of the camera, and cannot modify the hardware (lens, CCD chips, sensors or switches). A firmware update cannot make an older model camera equivalent to the model that "just came out."
