Pentax BG-10 for MZ-S - AA Battery Pack/Grip with vertical shooting release button

Powered by four AA-sized alkaline or lithium batteries and featuring a matching design with the MZ-S camera body, this grip dramatically increases the number of film rolls that can be taken without having to change batteries. It also comes equipped with an extra shutter release button for vertical-position shooting, an AE lock button, a preview lever, a remote shutter release function, and vertical-position strap lugs. Thanks to its original mount mechanism, this grip can be attached to and removed from the MZ-S in a matter of seconds.
