Hasselblad 907X Optical Viewfinder ( for XCD 21, 30 and 45mm )
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.
