Lens Overview — AstrHori 75mm f/4

The AstrHori 75mm f/4 is a manual focus prime lens built for the medium format camera system, designed to mount via a Lens Board fitting compatible with technical cameras. As a prime lens with a fixed 75mm focal length, it sits in the telephoto range and delivers a maximum aperture of f/4. The lens is engineered specifically for medium format imaging, making it a purposeful choice for photographers who work with large format or technical camera setups requiring lens board mounting.

Manual focus operation puts full control in the photographer's hands, which suits the deliberate, methodical shooting style typical of technical camera work. Weighing 675g, the lens has a solid, substantial build that reflects the demands of medium format glass. The 67mm filter thread provides a common filter size that is easy to source accessories for.

With no image stabilization on board — which is standard for technical camera lenses where camera movement is controlled through the system itself — the AstrHori 75mm f/4 is a straightforward, spec-driven tool for medium format and technical camera photographers seeking a compact telephoto prime at a competitive price point.
