Product Features in Detail
Rubber-coated focus ring
The ergonomic, anti-slip, rubber coated focus ring makes for a practical, user-friendly lens. This lightweight option is ideal for on the go photography, without any compromise on optical quality.
Retaining ring
The retaining ring of the frontal lens is free from engraving, printing or any other form of marking. This therefore prevents unwanted internal reflections when using high density filters.
Focus lock
You can lock the focus ring at any time securing the setting that you choose. Precision, comfort and ingenious solutions.
Infinity click and hyperfocal scale
The hyperfocal distance scale simply and intuitively gives information about accessible range for depth of field for a given aperture. When the ring is set in the “infinity” position, there is a noticeable “click”, making it easier to find the value without looking. Now you can fix your eyes on the image and concentrate on the composition.
Focus calibration
We have made every effort to ensure that each lens leaving the factory has been properly calibrated. However, for your comfort Irix lens provides you the unique opportunity to calibrate the lens for a particular model of your camera.
Extreme weather resistance
Irix lenses are made with phenomenal precision. Each Irix lens is equipped with a weather sealed construction which protects the interior against dust and moisture. Thanks to inner seals, our lenses are also protected from accidental water splashes.
Intelligent Filter Options
We offer you excellent wide-angle lenses with front and rear filter options. Our lenses feature an ingenious way to easily access a rotatable filter through use of a window on the petal-shaped lens hood. Next to this, we have also included a rear filter slot for gelatin filters, offering you even more opportunity for filter use.
