Description
Product Overview
The eTone 35mm 135 to 120 Film Converter is engineered to bridge the gap between 35mm roll film and 120 medium‑format backing paper, delivering a seamless workflow for photographers, laboratory technicians, and autoradiography specialists. Constructed from high‑impact, food‑grade plastic, the tool balances durability with lightweight portability, ensuring it can endure the rigors of daily studio use while remaining easy to carry into the field. Its dimensions—5.12 x 3.94 x 1.38 inches—fit comfortably in a standard lab bench drawer, and at just 1.83 ounces, it adds negligible weight to any equipment kit. The design incorporates a precision‑cut guide that aligns the 35mm film strip perfectly with the 120 backing paper, eliminating skew and guaranteeing consistent exposure across the entire frame. The converter also features a flexible capacity chamber capable of holding up to 135 rolls of varying lengths, allowing users to batch‑process large volumes of film without frequent reloading.

Usage
In a typical laboratory or studio setting, the eTone converter streamlines the process of preparing 35mm film for medium‑format exposure. Begin by placing a roll of 35mm film into the loading slot; the internal rollers guide the film onto the backing paper with a smooth, tension‑free motion. Once the film is aligned, the user pulls the backing paper through the exit guide, where the film is securely attached and ready for insertion into a 120‑format camera. This workflow is especially valuable for autoradiography applications, where precise film placement is critical for accurate imaging of radioactive samples. The tool’s universal compatibility means it works flawlessly with a wide range of 120‑format cameras, including Pentax, Rolleiflex, Mamiya, Hasselblad, Bronica, and many others. Whether you are shooting on location, conducting scientific documentation, or managing a high‑throughput imaging lab, the converter reduces setup time, minimizes film waste, and enhances overall productivity.
