Irix's fast standard prime — 45mm f/1.4 with weather sealing for DSLR mounts.
The Irix Dragonfly 45mm f/1.4 is a fast standard prime from Swiss-Korean brand Irix, available for Canon EF and Nikon F mounts. The 45mm perspective is slightly wider than 50mm. The Dragonfly designation indicates the lighter build vs the Firefly.
Optically good — sharp from f/2 with pleasant rendering. The 45mm focal length sits between 35mm and 50mm — a unique perspective. Weather-sealed construction — unusual at this price point. Manual focus with electronic contacts for EXIF.
Available for Canon EF and Nikon F. Weather-sealed construction. Electronic contacts for EXIF and metering. Approximately 700g — heavy for 45mm. Dragonfly (light) and Firefly (robust) build variants available.
Available used at mid-range prices. Irix is a niche brand — limited market presence but genuine optical quality. The 45mm focal length is unusual — neither standard 50mm nor wide 35mm. For those wanting a different perspective with weather sealing.
