Lens Overview — Horseman 105mm f/3.5

The Horseman 105mm f/3.5 Seiko SLV is a medium format prime lens built for precision imaging in professional and enthusiast applications. With a fixed focal length of 105mm and a maximum aperture of f/3.5, this lens sits in the standard focal length range for medium format systems, making it a versatile option for portrait, documentary, and studio work. The lens is entirely manual focus, which suits deliberate, methodical shooting styles common in medium format photography where careful composition and precise focus control are prioritized over speed.

The Seiko SLV designation references the lens's shutter mechanism, a notable characteristic of certain medium format lenses that integrates a leaf shutter directly into the barrel rather than relying solely on the camera body's shutter. This design allows for flash synchronization across a wide range of shutter speeds — a practical advantage in controlled lighting environments. The lens mounts via a proprietary or specialist mount categorized as 'Other,' so prospective buyers should confirm compatibility with their specific Horseman body or technical camera system before purchasing.

No image stabilization is present, consistent with the manual, tripod-friendly workflows typical of medium format shooting.
