Viltrox AF 24mm F1.8 FE

Reviewers found the centre sharp from f/1.8, with mid-frame and corners needing f/4 to f/5.6 to match. Vignetting is heavy wide open and some longitudinal colour fringing shows on high-contrast edges. Coma is moderate, which makes it usable but not class-leading for night skies.

Autofocus is accurate and supports Eye AF, but it is slower and noisier than Sony's own primes, and early firmware had some hunting in low light. The metal build and the price compared with Sony and Sigma 24mm options are the main selling points.

Owners like the solid metal construction, the matching look and filter size across the F1.8 FE set, and the price. Many bought it as part of a 24/35/50 kit for travel and events.

Common complaints are soft corners at f/1.8, AF that hesitates in dim light, and firmware updates needed to fix compatibility on newer Sony bodies. Some find the aperture ring easy to knock out of the A position.
