VZ-6617 film camera lets photographers switch frame sizes mid-roll

The sharpest idea in film right now is also the easiest to grasp: the VZ-6617 lets photographers change frame size from 6x6 to 6x17 in the middle of a single roll of 120 film. Exposing Engineering launched the camera on Kickstarter on April 14, with first units targeted to ship in June 2026, and the pitch is aimed squarely at a long-standing film frustration: choosing one format for an entire roll before the first frame is even exposed.

At the center of the camera is the Variable Zone Film Gate, a mechanism built from sliding panels that move in sync to create stepless frame sizes from square to panoramic. Exposing Engineering says the body is self-contained, so there is no need to pull off a film back or swap plates between shots. That changes the way a roll can be used in the field. A portrait can start at 6x6 for a tight, balanced composition, then shift to 6x17 for a horizontal environmental frame without waiting for a second camera.

That flexibility matters because medium format has always pushed photographers to think hard about aspect ratio. A square frame can suit a face, a doorway, or a travel detail. A 6x17 frame can turn the same street corner into a wide scene with room for sky, architecture, and distance. For anyone moving between portraits, landscapes, and travel work, the VZ-6617 tries to remove the usual tradeoff between carrying the “right” camera and making do with the one in hand.

The camera is built for large-format view-camera lenses and uses interchangeable lens cones. Exposing Engineering says it ships with a matching cone, while buyers supply the lens they want to use. The system relies on zone focusing and includes a cold-shoe-mounted optical viewfinder optimized for 6x17 and a 90mm focal length, with a modular ground-glass accessory still in development. The company also says the first production round will be funded through Kickstarter before direct sales begin.

The VZ-6617 is in beta with a small group of testers, and founder Francis Garing has said the project grew out of the same panoramic impulse behind earlier systems like Custom Camera Building’s CCB and the Sasquatch Camera. That lineage is real, but the VZ-6617 pushes the idea further by treating the frame itself as adjustable gear. In a medium-format world built around fixed boxes, that is the useful disruption: not a novelty for its own sake, but a way to let one roll hold a square portrait, a travel scene, and a 6x17 landscape without changing cameras.
