IRIX 45mm f/1.4 Overview

Combining a versatile normal focal length with fast design, the Nikon F-mount Irix 45mm f/1.4 is a useful prime lens characterized by its manual focus operation and weather-sealed design. The bright f/1.4 maximum aperture excels in low-light conditions and also offers increased control over depth of field for working with selective focus techniques. The optical design incorporates a series of specialized elements to reduce a variety of aberrations in order to produce sharp and color-accurate imagery.

Complementing the optical assets is a robust physical construction, dubbed Dragonfly, which incorporates extensive weather sealing to guard against dust and moisture. This manual focus lens also features printed focus distance and depth of field scales to benefit fast and accurate focusing, and a rounded nine-blade diaphragm contributes to a smooth bokeh quality.

Normal-length prime is compatible with FX-format Nikon F-mount cameras, however can also be used with DX models where it provides a 67.5mm equivalent focal length.
Impressive f/1.4 maximum aperture suits working in a variety of lighting conditions and also affords great control over depth of field for isolating subject matter using selective focus techniques.
One aspherical element and four high refractive index (HR) elements help to minimize spherical aberrations and distortion in order to achieve high sharpness and accurate rendering.
One extra-low dispersion element suppresses color fringing and chromatic aberrations for a high degree of color fidelity and clarity throughout the aperture range.
Manual focus design is benefitted by a positive focus lock mechanism to secure your focus position at any point to limit unwanted shifting of focus. Also, an internal focusing design maintains the overall length of the lens during operation.
Depth of field scale benefits using hyperfocal and pre-focus techniques and lens engravings are filled with UV-reactive paint to make them readable in low-light conditions.
Dragonfly finish incorporates weather sealing to guard against dust and moisture.
Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
Integrated CPU enables camera-based aperture control along with focus confirmation.
Includes complimentary additional rear lens cap.

Hello yes..I can't find much info on the IRIX 45 MM other then youtube and there is not a long of info. I've been using Sigma art 50mm and 85mm for a while. I'm in the market for a new lens. I do a lot of vblog and my camera body is Nikon d7200. Please can you provide me any info on IRIX 45mm and how will it work with my Nikon d7200. I look forward to hearing from you?
Asked by: Rodq
Irix makes very good quality lenses and are manufactured very well. This is of course a manual focus lens, so no autofocus but will marry up with your camera quite well if you are looking for a focal range of about 65mm.
