Half-mirror rig

The lid is raised showing the half-mirror ( 50% reflection 50% transmission ). The stereo base can be adjusted ( 5mm to 25mm ) by moving the 'right' camera on the bar. This set up allows stereo macro photos / movie clips. The rig can be hand held or mounted on a monopod or tripod. Different lenses can be added to the Nikon 1 V1 cameras for different amounts of magnification. The above arrangement shows Nikkor 30-110mm lens with a 16mm extension tube. For a typical situation with the subject about 80mm in front of the base part of the rig. The lenses would need to be set to 51mm focal length for focusing and an object 39.5mm wide would fill up the side to side of the sensor in the camera. The angle of view would be 11.0 degrees.

A later addition is an infra-red attachment ( one receiver to two wired IR led transmitters, powered by 5V battery ). The two transmitters are clipped onto the two cameras just over the IR sensors on the camera. A hand held Nikon remote unit ML-L3 is aimed at the receiver to trigger both cameras together. It is best for the cameras to be in manual focus mode to get a good sync.
