IRIX 30mm f/1.4 Dragonfly Lens for Pentax K

The 30mm f1.4 Dragonfly Lens for Pentax K from IRIX features an optical design based on the IRIX 30mm Cine model, intended for the highly demanding film industry market. The entire optical structure of the lens is identical in both the still and cine versions, designed to emphasize the vividness of the image. This lens features a modern optical design that includes three ultra-low dispersion glass elements, two high reflectance glass elements and one aspherical element. There is a total of 13 elements in 11 groups to provide sharp details, vivid colors, and ultra-low distortion. In addition, the 11-blade design aperture with rounded edges ensures a pleasant and vivid background bokeh. The elements feature Neutrino multicoating for optimal light transmission without lens flare.

The premium construction materials ensure operation in extreme environmental conditions, and a system of seals located in key places of the lens resist moisture and dust, protecting the cleanliness of the mirror chamber and the sensor of the camera. The manual focus design incorporates rear focusing so that the lens does not change dimensions while focusing. A special focusing ring with a characteristic shape is hallmark of IRIX design, and special texturing and properly selected rubber material and the dedicated emboss makes it easy to feel the ring s position. The Focus Lock function allows the focusing ring to be locked in a specific position, especially useful when keeping a specific camera-to-subject distance while zone-focusing, or when keeping perfect focus at infinity in landscape photography or astrophotography.

The IRIX 30mm f/1.4 lens can be controlled directly from the camera, making semi-automatic modes (PASM) and data recording in Exif format available. The use of electronics also enables the lens to be equipped with a focus confirmation system in enabled camera bodies. The camera will report the correct focus setting, either in the form of an icon in the viewfinder or as a sound, when the focus is correctly set.
