Reminiscent of the Hasselblad SWC viewfinder, the optional 907X Optical Viewfinder (OVF) enables simple eye level shooting. Used in combination with the 907X 50C, it is easily mounted on the camera body via a cold shoe adapter. The OVF has a wide field of view and markings for XCD 21, 30 and 45mm and a center cross for an autofocus point.
