Notes and Comments
The K2 Zoom Reflex Automatic was a slightly improved version of the previous Bolex K1. The lens was the same Kern 8-36mm, but offered a powered zoom function with control buttons located on the top of the camera body.
Other improvements to the K2 included a through-the-lens exposure system (only sensitive to 10-200 ASA film) and an additional speed of 24 frames per second.
