Description — Horseman 90mm f/5.6
The Horseman Super ER is a 90mm wide-angle prime lens built for large format photography and paired with a Seiko-SLV leaf shutter. With a maximum aperture of f/5.6 and a fixed focal length, this lens offers a consistent optical perspective suited to the demands of large format image-making. The manual focus design is fully in keeping with large format shooting practice, where precise focus is achieved on the camera's ground glass before exposure.
The integrated Seiko-SLV shutter is a key feature, enabling between-the-lens shutter control and flash synchronization across its speed range — a practical benefit for controlled lighting environments. Image stabilization is none, which is standard for this lens category. The lens is classified as wide-angle within the large format system context.
No filter thread size or weight data is currently available in the product specifications, so buyers should confirm these details prior to purchase. This is a straightforward, purposefully built prime optic for large format practitioners.
Pros — Horseman 90mm f/5.6
- ✓Fixed 90mm focal length prime design ensures optical consistency with no zoom-related compromises
- ✓Wide-angle classification makes it a practical choice for expansive compositions in large format work
- ✓Integrated Seiko-SLV leaf shutter provides flash sync capability inherent to between-the-lens shutter systems
Cons — Horseman 90mm f/5.6
- ✗Maximum aperture of f/5.6 limits light gathering compared to faster large format alternatives, which can make ground glass focusing in dim conditions more challenging
- ✗No filter thread size is provided in the specifications, making filter compatibility research necessary before purchase
- ✗Weight is unspecified in the data, so buyers cannot assess tripod or field kit load without further research
