Lens Overview — Horseman SW-D II Pro

The Horseman 35mm f/4.5 Apo-Sironar Digital Lens is a prime wide-angle optic purpose-built for the Horseman SW-D II Pro technical camera system. Designed for the medium format camera system and classified as a large format lens, it mounts via a standard Lens Board (Technical Camera) interface, making it a dedicated fit for technical camera workflows rather than a general-purpose interchangeable lens. With a fixed focal length of 35mm and a maximum aperture of f/4.5, this is a manual focus-only lens — there is no autofocus capability and no image stabilization, consistent with the demands of deliberate, tripod-based large format shooting.

The lens carries a 67mm filter thread, giving photographers access to a wide range of standard screw-in filters for contrast management, polarization, or neutral density use in the field. Weighing just 0.3kg, it is a reasonably compact option for what is fundamentally a large format optic. Focus is entirely manual, which aligns with the precision-oriented shooting style typical of technical camera work.

For photographers already invested in the Horseman SW-D II Pro system, this lens represents a factory-matched wide-angle solution with a straightforward, purpose-driven specification set.

Key Features — Horseman SW-D II Pro
