IRIX 30mm f/1.4 Dragonfly Lens for Nikon F Review

The IRIX 30mm f/1.4 Dragonfly is a wide-angle prime lens for Nikon F-mount cameras that combines a fast maximum aperture with weather-sealed construction at a competitive $349 price point. Built with 13 elements in 11 groups (including three ultra-low dispersion, two high-refractive, and one aspherical element), it's designed to deliver sharp images with minimal chromatic aberration and distortion. The Neutrino lens coating aims to reduce flare and ghosting in challenging lighting.

Manual focus only, the lens includes a focus lock mechanism and focuses as close as 13.38 inches. The 11-blade rounded diaphragm is engineered for smooth bokeh, while the weather sealing and rubberized mount protect against dust and moisture. At 30mm, it sits between the more common 24mm and 35mm focal lengths, offering a perspective useful for environmental portraits, street photography, and general walkaround shooting on full-frame bodies. The combination of wide aperture, weather resistance, and affordable pricing positions it as a value-oriented option for Nikon shooters who prioritize manual control and build quality over autofocus convenience.
