Description
IRIX 15mm f/2.4 Dragonfly Overview
By Photo’s Matt Cottom
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.
Designed with the highest image quality in mind, this prime lens includes two aspherical elements and two low-dispersion glass elements to minimize optical aberrations such as distortion and vignetting, resulting in high-resolution images with excellent sharpness and color fidelity. A Neutrino coating has been applied to limit lens flare and ghosting for improved contrast and color fidelity. Manual focus design is benefitted by a positive focus lock mechanism to secure your focus position at any point to limit unwanted shifting of focus. Click On/Off switch allows you to choose between gradual and smooth iris ring operation. Large depth of field scale benefits using hyperfocal and pre-focus techniques. 95mm front filter threads for screw-in filters. Includes tulip-shaped lens hood.
