On the coating, Irix said its lens uses Neutrino Coating to reduce ghosting, flare and bad light. The new special features such as focus lock, infinity click and hyperfocal scale set a new level of manual lens functionality. Focus lock enables to lock the focus ring at any time enssuring the chosen settings. Hyperfocal distance scale gives information about the accessible range for depth of field for a given aperture simply and intuitively. When the focusing ring is set in the “infinity” position, there is a noticeable “click” (infinity click), making it easier to find the value without looking.
These parameters are usually seen on the Irix lenses, manufacturers engraved fluorescent markings that reflect the light enable easy operation in all lighting conditions.
