f/2.4 maximum aperture. 15mm focal length (full-frame ultra-wide, approximately 110° diagonal field of view). Manual focus. At approximately 390g. Canon EF mount.

The Irix 15mm f/2.4 is used for landscape, astrophotography, and architectural photography — f/2.4 at 15mm provides good light gathering for star photography. The Firefly version uses a lighter aluminum barrel than the heavier Blackstone model.

On the used market the Irix 15mm f/2.4 Firefly Canon EF is a capable ultra-wide prime. Condition checks: front element (exposed), focus ring. Canon EF mount — manual focus.
