Viltrox's popular APS-C fast prime — 35mm equiv at f/1.4 with AF for multiple mirrorless mounts.
The Viltrox AF 23mm f/1.4 STM is a fast wide prime for APS-C mirrorless cameras, providing 35mm equivalent at f/1.4. It quickly became one of the most popular budget fast primes — offering f/1.4 AF performance at a fraction of first-party prices.
Optically good for the price — sharp from f/2 with pleasant bokeh at f/1.4. Stepping motor AF is quiet and reasonably fast. Eye-detect AF works on compatible bodies. USB-C port for firmware updates — Viltrox actively improves AF performance.
Available for Fujifilm X, Sony E, Nikon Z, and Canon RF mounts. 52mm filter thread. Approximately 260g. No weather sealing. Minimum focus distance 30cm. 9 rounded aperture blades.
Very common used and excellent value — one of the best-selling budget fast primes. The Fuji XF 23mm f/1.4 R and R WR versions are optically superior. Check for firmware updates. Some copies show AF inconsistency — test before committing. Outstanding value for the price.
