Description — Viltrox 20mm f/1.8 ASPH
The Viltrox PFU RBMH 20mm f/1.8 ASPH is a manual-focus ultra wide-angle prime lens built for the Sony E mount and designed to cover a full-frame image circle. The fixed 20mm focal length places it firmly in wide-angle territory, making it well suited for landscape, architectural, and environmental photography where a broad field of view is the goal. The f/1.8 maximum aperture gives photographers meaningful light-gathering ability for a lens of this type.
Weighing in at 782g, the lens has a solid, substantial feel. The 82mm filter thread is worth noting for anyone planning to stack filters into their workflow — you'll need to source accessories at that diameter. With no autofocus and no image stabilization, this lens demands a deliberate, hands-on shooting approach.
Photographers comfortable with manual focusing who want a wide, fast prime for Sony E-mount mirrorless cameras will find the core specifications here — 20mm, f/1.8, full-frame, Sony E — straightforward and purpose-driven.
