Irix Cine 45mm T1.5 Nikon Z Imperial Cinema Lens

On a documentary shoot in a dimly lit interior, the Irix Cine 45mm T1.5 for Nikon Z lets you keep rolling without pushing ISO to noisy levels. Its fast T1.5 aperture renders a shallow, creamy depth of field that isolates your subject, while the 180° focus throw and 0.8 MOD gears give your focus puller the precision needed for repeatable rack focuses. Full-frame coverage and a 51.4° angle of view make this lens equally at home on narrative sets, commercial productions, or run-and-gun projects where reliability matters.
