Irix announces 45mm F1.4 Dragonfly lens for Fujifilm GFX medium format cameras. Irix 45mm f/1.4 is a standard 45mm wide-angle Dragonfly lens that offers a 35mm full-frame-equivalent field of view (62.64º) when used on medium format.
The lens construction consists of eleven elements in nine groups, including one aspherical element, one extra-low dispersion element and four high-refractive elements. Irix 45mm f/1.4 GFX Lens offers an aperture range from F1.4 to F22, has a minimum focusing distance of 40cm (15.75”), uses a nine-blade aperture diaphragm and has a 77mm front filter thread.
The lens is constructed of a magnesium housing and uses seals in five ‘key areas’ for improved protection against the elements. It features a smooth aperture ring and its focus ring offers 170º of rotation in addition to a focus lock switch. Irix also says the lens features less than 1% distortion. Its measurements come in at 87mm (3.43”) diameter, 144mm (5.67”) long and it weighs 1120g (2.47lbs).
The Irix 45mm f / 1.4 GFX comes in a Dragonfly finish that combines the lightness and excellent ergonomics of the Firefly version with the durable magnesium housing used in the Blackstone series lenses. The lens has also seals located in 5 places, which protect the lens during work in difficult weather conditions.
