Description — Viltrox 27mm f/1.2
The Viltrox 27mm f/1.2 is an APS-C prime lens for mirrorless systems, available in Fujifilm X and Sony E mounts. Its f/1.2 maximum aperture is one of the headline features, offering photographers a meaningful advantage in lower light conditions and giving significant control over background separation. The fixed 27mm focal length sits in the standard range, well-suited to general-purpose shooting including street, environmental portraiture, and travel photography.
Both autofocus and manual focus are supported, providing flexibility across shooting styles and scenarios. The lens takes 52mm filters, a compact and widely available size. At 300g, it is light enough to carry all day on a mirrorless body.
It is worth noting that no image stabilization is included, so shooters on bodies without IBIS should factor that into their handholding approach. The APS-C format designation means this lens is optimized for crop-sensor mirrorless cameras rather than full-frame systems.
