An impressively wide prime lens, the Sony E-mount 15mm f/2.4 Dragonfly Lens from IRIX meshes an advanced optical design with lightweight and durable physical construction. The expansive field of view is complemented by a sophisticated optical layout that utilizes low dispersion, aspherical, and high-refractive glass elements, as well as a Neutrino coating, to render imagery with low distortion, controlled spherical and chromatic aberrations, high contrast, and natural color rendering.
In addition to the imaging performance, this 15mm f/2.4 utilizes a manual focus design for fine-tuned control and incorporates a unique positive focus lock to secure the focusing position at any point for consistent, repeatable shooting. As the Dragonfly version of this focal length, this lens is also distinguished by its printed lens markings, tactile controls, and weather-sealing throughout the lens housing for working in adverse environmental conditions.
