Description — Horseman 180mm f/5.6
The Horseman 180mm f/5.6 P.T Seiko is a large format prime lens designed for use with technical cameras via a Lens Board (Technical Camera) mount. It features a fixed 180mm focal length — classified as a standard focal length range in large format photography — paired with a maximum aperture of f/5.6. Focus is entirely manual, making it well-suited to the measured, precision-driven approach that large format technical camera work demands.
With no image stabilization, users will want to employ appropriate camera support for the sharpest results. As a prime lens, it offers a single dedicated focal length with no zoom function, keeping the optical design focused on quality at that specific focal length. The lens board mounting system is a standard interface for technical cameras, though buyers should confirm board compatibility with their own camera system prior to purchase.
Filter thread size and weight data are not available in the current specifications.
