The Sony Battery Grip rental fits the Sony A7, Sony A7r and Sony A7s cameras. Ability to use 1 or 2 NP-FW50 batteries enables longer shooting times. The battery can be replaced while the camera is on -- pretty cool! You also get an extra shutter button, both back & front control dials and automatic exposure lock.
