The primary component needed for photo or video work with the RZ system is the MA751 photo/video attachment. This accessory allows you to use 35mm, large-format Polaroid, digital or video cameras. The attachment contains a beam-splitter prism which can be slid into the light path to redirect 80% of the light from the eyepieces into the vertical photo tube behind the viewing head. With the beam splitter in position, the user can view the specimen through the eyepieces while taking pictures.
