Designed around the camera
Each holder is developed from the original back interface so register depth, rail engagement and film position remain the priority.
Newly manufactured 9x12 film holders and sheet-film adapters for classic European plate cameras, designed to use modern 9x12 cm sheet film while respecting the camera’s original back interface and film plane.
The holder designs are now essentially complete and field testing has begun on real cameras and film.
ICA Volta and Contessa-Nettel Sonnar · 9x12 cm
Each holder is developed from the original back interface so register depth, rail engagement and film position remain the priority.
The design focuses on practical use with currently available sheet film, without asking collectors to rely on rare original inserts.
Designed, assembled and individually checked in Switzerland, with development driven by real cameras rather than catalogue assumptions.
Many classic 9x12 cameras survive with good lenses and working shutters, but without usable holders. In other cases, original cassettes exist yet are difficult to load consistently, missing parts, or no longer trustworthy for light-tight field use.
Classic Film Holders focuses on replacement holders that respect the camera's original geometry while reducing the friction of actually making photographs with it.

The first holder in development is a 9x12 cm model for the ICA Volta family. It is intended for photographers who have a working camera body but need a reliable, newly made holder for practical use.

A dedicated replacement holder for the Contessa-Nettel Sonnar, developed and physically fitted on a real camera. The design keeps the original camera usable with modern 9x12 cm sheet film while preserving the existing back interface.
The mechanical design and core construction of the ICA Volta and Contessa-Nettel Sonnar holders are now essentially complete.
Real film exposures are now being used to check film-plane accuracy, handling, light-tightness and reliability in normal photographic use.
Any final production refinements will follow the field tests. Pricing, lead times and ordering details will be published after that stage.
