Viltrox E 20mm f/2.8

The Viltrox 20mm f/2.8 is an affordable, compact wide‑angle prime aimed at photographers who want a lightweight, ultra‑wide field of view without a high price tag. Its short focal length provides dramatic perspectives for landscapes, environmental street scenes and interiors, and the f/2.8 maximum aperture is helpful in low light and for star‑field photography when combined with modern sensors. Optical engineering in this class focuses on balancing a large imaging circle and controlling distortion, coma and vignetting via careful element design and coatings; while it may not out‑resolve the most expensive wide primes, the lens often punches above its price point with good centre sharpness and usable corner performance for many real‑world applications. Autofocus capability makes it practical for run‑and‑gun shooting and hybrid stills/video use, and its small footprint suits travel and minimalist kits. Photographers who accept modest compromises in the extreme corners in exchange for portability and cost‑effectiveness will find the 20mm f/2.8 a compelling option for landscapes, night skies and editorial street work.
