Hacking a Broken Stereo Camera Into an Ultra-Wide Panoramic Rig
Instead of shopping for a rare panoramic camera, Reddit user u/-gingerninja turned a broken Soviet-era FED stereo body into something far more radical. Stereo cameras normally expose two 35mm frames side-by-side, leaving a generous 47mm gap between the image pairs. By exploiting this unused area, the creator cut a much wider film gate and re-engineered the transport so that each exposure uses a double advance of the film. The result is a panoramic frame that stretches to around 93mm across 35mm film, dramatically surpassing the standard 24×36mm frame and even the famed Hasselblad XPan format at 24×65mm. Mounted with a leaf‑shuttered medium‑format lens on a custom helicoid, the hybrid body behaves like an analog panorama monster, capturing sweeping scenes in a single exposure while squeezing about 15 giant frames onto a roll of 35mm.
Beyond XPan: Redefining Extreme Field of View on 35mm Film
Commercial panoramic systems like the XPan and various 85mm gate designs have long set the practical ceiling for wide angle photography on 35mm film. This panoramic camera build simply ignores that ceiling. By pushing the frame width out to roughly 93mm, it not only outpaces the XPan’s 65mm span but also overshoots common 85mm panoramic formats, edging into what some commenters jokingly dub an “XXPan” experience. At this size, composition changes completely: horizons stretch almost cinematically, foreground details can be anchored at one edge without losing context, and the aspect ratio encourages storytelling across the frame. Because a roll yields just 15 exposures, each shutter press becomes a deliberate act. This scarcity, combined with the extreme field of view, nudges photographers toward slower, more intentional image-making that stands apart from both digital filters and standard 35mm frames.
Custom Camera Engineering Meets DIY Maker Culture
At the heart of this project is the Schneider Super Angulon 47mm f/5.6, a cult favorite in DIY circles. Designed for medium-format and large-format work, it casts an image circle of about 123mm—far larger than any 35mm frame needs. By using only roughly 60% of that circle, the builder gains enough coverage to support the 93mm gate with generous room to spare, minimizing edge falloff and vignetting. The lens is paired with zone focusing rather than a rangefinder or autofocus system, keeping the build mechanically simple and robust. This combination of surplus optics, repurposed film bodies, and hands-on machining is emblematic of a broader movement: photographers who refuse to wait for manufacturers to release niche gear. Instead, they tap into maker culture, leveraging 3D printing, scavenged parts, and community knowledge to prototype their own extreme wide-angle imaging tools.
What This Ultra-Wide Experiment Signals for the Future of Panoramic Cameras
The buzz around this DIY panoramic camera underscores a growing reality: the most adventurous ideas in wide angle photography are emerging from hobbyist workbenches, not corporate R&D labs. By proving that a hacked stereo body and a widely available wide‑angle lens can eclipse every commercial 35mm panorama, the project quietly challenges manufacturers. If one individual can engineer a 93mm frame with existing components, why haven’t mainstream brands offered similarly radical film or digital panoramic systems? For now, the answer may lie in niche demand and production economics. But as online communities share more successful panoramic camera builds, expectations will likely shift. Camera companies could respond with modular systems, wider native aspect ratios, or lenses optimized for extreme field of view. Until then, the frontier belongs to tinkerers willing to cut their own film gates and build the cameras they wish existed.
