IRIX 45mm T1.5 Cine (ft) Overview
Designed for cine-style image capture and covering up to full-frame size sensors, the white Nikon Z-mount 45mm T1.5 Cine Lens from IRIX incorporates multiple internal and external design features. 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, and five seals protect against inclement weather and dust.
To help eliminate aberrations and distortion, the IRIX 45mm T1.5 Cine Lens is constructed with 11 optical elements in nine groups, including four HR (high refractive index) and three ED (extra-low dispersion) elements. This lens has 180° of focus and 75° of iris rotation and incorporates an 86mm front filter thread.
45mm Focal Length
A 45mm focal length with the Nikon Z lens mount is ideal for capturing crisp details and vibrant colors.
Full-Frame Coverage
The 43.3mm image circle of this lens covers up to full-frame format sensors.
Rounded Bokeh
Produces the "IRIX look" with shallow depth of field and a 9-blade iris for smooth, rounded bokeh.
Fast T1.5 Aperture
- Fast T1.5 maximum aperture enables you to capture images in low light levels without having to crank up your ISO setting.
- Matching maximum aperture, color, and contrast with the 21 and 45mm primes.
Magnetic Mount System (MMS)
- Like the rest of the Cine series (except the 11mm), the 45mm prime features the Magnetic Mount System (MMS).
- Provides compatibility with the separately available, magnetically stacking IRIX Edge MMS filters and the MMS Lens Hood.
Weather Sealing
Sealed against rain, snow, and dust like the rest of the IRIX cine series and able to withstand a wide range of temperatures.
0.8 MOD Gears
Cine-style 0.8 MOD geared focus and aperture rings.
95mm Front Diameter
Industry-standard 95mm front diameter is compatible with most matte boxes.
Smooth Focusing
The adaptive focus ring adjusts smoothly between manual and motor control.
Focus Marks in Feet
Luminous markings in feet are engraved for durability.
