Description — 7artisans 18mm f/6.3 UFO
The 7artisans Photoelectric 18mm T6.3 UFO Lens is a large format, ultra wide-angle prime built for technical cameras in the mirrorless ecosystem. Mounted via a Lens Board (Technical Camera) interface, it delivers an 18mm focal length at a fixed T6.3 aperture with entirely manual focus operation — no autofocus, no image stabilization. At just 49 grams, it is remarkably light for a large format lens, offering genuine portability advantages for photographers who need a wide perspective without added bulk.
The prime design keeps things simple and predictable, with a single fixed focal length suited to wide-angle compositional work. There is no filter thread on this lens, so filter use will require alternative mounting solutions.
