Lens Overview — AstrHori 28mm f/13

The AstrHori 28mm f/13 is a manual-focus prime lens designed for large format technical cameras, mounting via a standard Lens Board interface. With a fixed focal length of 28mm and a maximum aperture of f/13, this lens is purpose-built for controlled shooting scenarios where precision and consistency take priority over speed. As a macro-type lens in the large format category, it occupies an interesting niche for photographers working with technical camera systems in studio or field environments where deliberate, methodical composition is the norm.

The lens is fully manual in every respect — no autofocus, no image stabilization — which aligns with the measured pace typical of large format work. Weighing in at 698g, it has a substantial feel appropriate for the technical camera rigs it pairs with. The Lens Board mount means compatibility is tied to technical camera systems that support this mounting standard, so shooters should verify fitment with their specific platform before purchasing.

For photographers already working in the large format mirrorless space who need a 28mm macro-type option with a familiar mount interface, the AstrHori 28mm f/13 presents a focused, no-frills solution worth serious consideration.
