Irix 21mm f/1.4 is another series of photographic lenses originating from the Cine line, so designed for a much more professional and demanding users from the cinema market. Both the photographic and film versions of this lens have exactly the same optical structure. The main differences concern the outer casing and the available mounts.

Top quality optics

The optical construction of the Irix 21mm f / 1.4 lens is based on 4 ultra-low dispersion glass elements, 4 high reflective and 2 aspherical elements. There are a total of 15 elements in 11 optical blocks. The lens is designed to work with the latest generation, full-frame 35mm sensors, i.e. with high resolution. A lot of emphasis was placed on limiting the distortion to the necessary minimum, it does not exceed 2%, so in practice it’s imperceptible. This allows you to successfully use this lens for all kinds of architectural photos. On the other hand, the combination of a very large relative aperture - f/1.4 with a well-controlled coma makes it an ideal tool for astrophotography. It’s also worth emphasizing the use of a new, 11-blade design of the aperture with rounded edges, which ensures a pleasant and very artistic bokeh of the background. It works in the range from f/1.4 to f/16.

Prepared for any conditions 

Irix optics are appreciated by professionals who want to be able to work regardless of weather conditions. That is why, for our most demanding customers, the lens is equipped with special seals that prevent the ingress of moisture and dirt into its interior. A special bayonet mount gasket also protects the mirror chamber of the camera. A dedicated lens hood primarily reduces unwanted light reflections but also acts as a protection for the front lens. When the lens is not in use, it can be safely stored in a dedicated hard case.

Compatible electronics

The Irix 21mm f/1.4 lens has electronic controls that allow you to control the aperture directly from the camera, making the popular semi-automatic (PASM) modes and EXIF data recording available. This facilitates and speeds up the work, also by allowing the use of correction profiles in the post-production process. The use of electronics in the lens also allows the lens to be equipped with a focus confirmation system - the camera will inform you about the correct focus (in the form of an icon in the viewfinder or a sound) every time you set the focus correctly.
