This is definitely one of the coolest cameras we have seen on the Impact lab, the DORYU 2-16 Pistol Camera. (Pics)

The DORYU 2-16 Pistol Camera was apparently issued to police in Japan and it has the same C mount as the 16mm movie camera, and the one in the photo features a Cine-Nikkor 25mm F1.4 lens .
