The Kohka 663 is compact super 8 movie camera from the late 1960s. It features a 10-30mm f1.8 zoom lens with through-the-lens metering. This is simple but well-built Japanese camera with a metal body and metal gearing.
Like all aerial focusing Super 8 cameras, it's sometimes difficult to perfectly the focus by eye alone in lower light situations where the depth of field is shallow. In such cases we recommend either measuring or estimating the focus distance and matching it with the lens distance number.
This camera requires four AA batteries (not included) for the motor; the light meter originally used two PX13 mercury batteries (which are no longer available) but we're including a voltage-reducing adapter which fits two common 357 silver oxide batteries (and also we're including the 357 batteries).
The camera is very good aesthetic and functional condition. We lubricated the main drive gears. The light meter and iris are responding to light correctly. We also verified the true film plane focus accuracy on an autocollimator.
