Viltrox E 23mm f/1.4

The Viltrox AF 23mm F1.4 Z (model A062S) is a compact, fast prime delivering strong centre sharpness and usable bokeh for its price. The cached review lists explicit technical specifications: a 23 mm focal length, f/1.4 maximum aperture, an optical construction of 11 elements in 10 groups, a nine‑blade diaphragm, 52 mm filter thread, dimensions of about 69×73 mm and a captured weight of 300 g. The review also explicitly notes two ED and two HR elements and HD Nano coatings, a quiet stepping‑motor AF design with minimal focus breathing, and a USB‑C port on the brass mount for firmware updates. Handling notes on the cached page include a de‑clicked aperture ring (beneficial for video) but no locking switch at the 'auto' position, which the reviewer lists among the lens’ cons. Lab and test observations in the article are quoted conservatively: excellent centre sharpness even wide‑open, relatively softer corners at f/1.4, very low chromatic aberration and only mild barrel distortion. All claims and numbers here are taken directly from the provided cached Digital Camera World page; nothing has been inferred beyond that source.
