The Holga Shutter Release Kit consists of a custom adapter that slips around the lens of the Holga camera, which allows for the camera to be triggered via a cable release. Included is also a 12" long shutter release cable with auto lock/unlock mechanism.
The adapter will not interfere with the new features of the Holga 120N, FN or CFN, including the tripod mount and the Bulb setting switch.
