Digitizing 35mm Film Cameras: “I'm Back Film” | Release #34

Digitizing Film Cameras

While there have been previous methods for digitizing film cameras by attaching a digital back and capturing the light image on the focusing screen, “I'm Back Film” may be the first project to attempt digital conversion while preserving the original form factor of a 35mm film camera.

At the heart of “I'm Back Film” is a cylindrical film canister (patrone) housing a red circuit board and sensor. This unit is inserted into a film camera in place of traditional film. The circuit board and sensor can be shifted laterally, allowing optimal alignment with the lens and film position unique to each camera. It utilizes Sony’s 20-megapixel Micro Four Thirds sensor, the IMX269.

By connecting to the “I'm Back Film” app, users can instantly review their captured images. The app is compatible with both iOS and Android. ISO sensitivity is adjustable from 100 to 6400, and the device offers a wide range of film simulations, including monochrome, KodakChrome, and Fujifilm, faithfully reproducing the look of popular film stocks.

The minimum pledge to receive the product is 639 Swiss Francs (approximately ¥107,000). Considering that existing digital backs are scarce and typically cost several hundred thousand yen even at the low end, this is a reasonable price point. For users who wish to enjoy the authentic aesthetics of a film camera while reducing long-term shooting costs, this gadget is an ideal solution. The ability to revert to analog photography at any time is also a compelling feature.
