The Focus Lock function is also a hallmark of Irix lenses – it allows you to lock the focusing ring in a specific position.

Manual focusing is facilitated by the characteristic focusing ring, which, thanks to the combination of a properly selected texture and rubber material, allows for precise focusing. Semi-automatic (PASM) modes and EXIF data recording are available on this model thanks to electronic controls, allowing the aperture to be controlled from the camera. The lens has a focus confirmation system on the camera display. Rigid carrying case supplied as standard.
Outstanding tightness to protect against dust and water.Engraved markings filled with UV-reactive ink.Anti-skid sharpening ring with special finish for easy sharpening.Reinforced internal structure based on metal elements.The lens housing is a continuation of the Dragonfly manufacturing standard known from earlier Irix models. Certainly, all amateurs of reportage and street photography will appreciate this feature.Įxternal construction – DRAGONFLY version It is also worth emphasizing the 11-blade diaphragm which provides a unique bokeh effect even despite the 21mm focal length. Thanks to this, and thanks to the f/1.4 aperture, the lens is perfect for widely understood astrophotography. The second parameter is the coma, also kept to a minimum level. Therefore, it’s not visible in practice, so the lens is ideal for all kinds of architectural photos or other subjects where image distortions are undesirable. The optical structure translates into two particularly important parameters – the first one is the perfectly corrected distortion, which does not exceed 2%. The lens was designed to work with the latest generation full-frame 35mm sensors, i.e. There are a total of 15 elements in 11 optical blocks.
The Irix 21mm f/1.4 is based on 4 ultra-low dispersion glass elements, 4 high refractive and 2 aspherical elements.
