Sigma 15mm f/1.4 DC DN Contemporary looks to be another hit from the company

Summary

The Sigma 15mm f/1.4 DC DN Contemporary lens, tested on an APS-C Fujifilm X-S20, provides a 22.5mm full-frame equivalent field of view that feels even wider in practice. It offers edge-to-edge sharpness, good contrast, and usable compositions without the exaggerations typical of ultra-wide lenses. The f/1.4 aperture is useful for low light and creates an unusual shallow depth of field for a wide-angle lens, while autofocus is reliable. For video, it exhibits minimal focus breathing and balances well on smaller bodies, though the aperture ring lacks a lock and there's no AF/MF switch. At $579, it's considered a versatile and reasonably priced option.
