Description — Horseman SW-D II Pro
The Horseman 35mm f/4.5 Apo-Sironar Digital Lens is a prime wide-angle optic engineered specifically for the Horseman SW-D II Pro technical camera. With a fixed 35mm focal length and a maximum aperture of f/4.5, it is built for the deliberate, precision-focused demands of large format shooting within a medium format camera system. The lens mounts via a Lens Board (Technical Camera) interface, ensuring a system-native fit with the SW-D II Pro.
Focus is fully manual — there is no autofocus, consistent with technical camera methodology where exacting control over every aspect of the image is paramount. A 67mm filter thread opens up compatibility with a wide range of standard screw-in filters, while the 0.3kg weight keeps the overall system manageable for location work. No image stabilization is present, so a solid support system is an essential companion. This lens is a straightforward, specification-matched choice for Horseman SW-D II Pro users seeking a dedicated wide-angle solution.
