“ Pentax BG-10 - Battery grip „
Powered by 4 AA-sized batteries, this grip can be easily attached to the MZ-S' bottom section and offers an extra shutter release for vertical position shooting and wireless remote control sensors front and rear. Further controls that are duplicated on the grip are depth of field preview and AE-lock button. Under standard conditions, the grip can provide power for approx. 95 rolls of 24-exposure film without flash, compared to approx. 50 rolls when using lithium batteries in the camera. The grip also improves the handling of the camera, making it slightly more comfortable to hold.
