Bellows Digital Camera, Handheld Size, KOKKA, 1950

I created an adapter to attach a Nikon 1 digital camera to a KOKKA hand-held bellows camera, enabling photography.
*The Nikon 1 in the images is not included.

"The KOKKA bellows camera is a medium-format and small-format film camera, primarily manufactured around the 1950s by Kokka Optical, a Japanese manufacturer." (From ChatGPT)

Images 13-17 were taken today, December 27, 2025, around 3:00 PM (overcast).

Attach the Nikon 1, switch the camera mode to Creative Mode, and adjust the shutter speed and ISO sensitivity for shooting.

Focus is roughly adjusted by extending the bellows, but fine-tuning is done using the dial at the bottom. (It may get stuck at the "feet" position; press the button to release it.)

Initially, there will be a smell of the adhesive used for the artificial leather, but it will gradually fade.

The included hood can be attached after removing the mount adapter, but if you pull it strongly upwards while the Nikon 1 is attached during removal, the attachment part may be damaged. Please remove the Nikon 1 first, and then push on a part other than the attachment area to pull it out.

There is dust on the lens, and the shutter does not function (it may not return; do not turn it from the "T" position).
The bellows has repair marks.

I have remade several of these, but each time I use a different type of camera, so each one is unique in the world.

Please judge the product based on the photos.
