Bronica 30mm f/3.5 Fisheye Zenzanon-PE Lens for ETR System {32.5 Screw-In}

Bronica's 30mm f/3.5 Fisheye for the ETR System

Fisheye lenses for medium format systems are genuinely rare, and the Zenzanon-PE 30mm f/3.5 is one of the few purpose-built options for the Bronica ETR, ETRS, and ETRSI bodies. At f/3.5, it offers enough light-gathering to work in situations where fisheye distortion would otherwise be paired with a prohibitively slow aperture. The 32.5mm screw-in filter thread gives you a path to adding effects or protection without resorting to improvised gel holders or drop-in solutions.

Fisheye optics at this focal length on a medium format body produce a field of view and rendering character that has no real equivalent in 35mm work. Photographers who have built their kit around the ETR system and want to push into extreme wide territory without switching platforms will find this lens fills a gap that almost nothing else addresses. The scarcity of dedicated medium format fisheye glass in the Bronica mount makes this a focused tool worth holding onto.

Who It's For

Experimental and fine art photographers drawn to the Bronica ETR system gain access to extreme wide-angle distortion that few medium format lenses offer, at a maximum aperture of f/3.5 that keeps it usable in lower light. Architectural and interior shooters who want to push spatial exaggeration beyond what rectilinear lenses allow will find the 30mm focal length delivers it without compromising ETR system compatibility. Documentary and editorial photographers who already shoot ETR or ETRS bodies and need an unusual perspective tool without changing platforms have a native-mount option here.

FAQ

What focal length and aperture does this fisheye offer?

30mm at f/3.5. That aperture is practical for medium format fisheye work, letting you shoot in lower light without the glacial speeds you'd typically accept with extreme wide glass.

Which Bronica bodies does this lens mount to?

ETR, ETRS, and ETRSI systems. The Bronica ETR mount is consistent across those bodies, so compatibility is straightforward.

What's the filter thread size?

32.5mm screw-in. You can thread on filters for effects or protection without jury-rigging gel holders or drop-in adapters.

How rare is this lens in medium format?

Dedicated fisheye glass for medium format Bronica mounts is genuinely scarce. This 30mm fills a gap that almost nothing else addresses for the ETR system.

What kind of field of view and rendering character does 30mm produce on this system?

The rendering on medium format at this focal length has no real equivalent in 35mm work. You're pushing into extreme wide territory with a visual character unique to the format and mount.

Is this lens compatible with other medium format systems?

No. It's mounted specifically for Bronica ETR bodies. Other medium format systems (Hasselblad, Mamiya, Pentax 67, etc.) require their own mount versions.
