Designed for up to 8K cine-style image capture and covering up to full-frame size sensors, the Nikon Z-mount IRIX 45mm T1.5 Cine Lens Z-Mount Feetfrom IRIX incorporates multiple internal and external design features. This 45mm mid-range lens has a field of view of 51.4°, depending on your camera's sensor. External features include a 95mm front diameter, 0.8 MOD gears, luminous focus marks in feet, and a detachable 1/4"-20 support foot.

Internally, nine blades produce smooth, rounded bokeh for natural-looking out-of-focus highlights. To help eliminate aberrations and distortion, the IRIX 45mm T1.5 Cine Lens is constructed with 11 optical elements in 9 groups, including three HRI (high refractive index) and two ED (extra-low dispersion) elements. A Multi-Start Thread focusing mechanism delivers quiet, precise focusing even in wet or humid conditions or in extreme temperatures. This lens has 180° of focus and 75° of iris rotation, an 86mm front filter thread, and front and rear caps. Four seals protect against inclement weather and dust.

Q: 9. What benefits, if any, would there be if I purchased the canon mount and used it on a Fuji XH2S with the metabones speedbooster?

A: The Metabones Canon EF lens to Fuji X-mount adapter would preserve the wide angle of the IRIX 30mm T1.5 Cine Lens as well as boost low light performance by 1 stop when used on crop sensor cameras like the Fuji XH2S. When using the IRIX 30mm lens without a speedbooster the lens would provide a 45mm view. When using the speedbooster the view would be 32mm.
