Verdict
Pick the Irix Firefly 15mm if you need an ultra-wide perspective on a tight budget and can work with its f/2.4 aperture. The Sigma 24mm stays the better choice if you prefer a brighter f/1.8 aperture for low light or shallower depth of field, and the 24mm focal length suits your framing needs.
