The NiSi Athena Prime 18mm T2.2 is a PL mount cinema lens for full-frame production, with a 46mm image circle, 300-degree focus rotation, 77mm filter thread, and 80mm front diameter. Its ultra-wide field of view, matched cinema mechanics, and rear filter holder are designed for narrative, commercial, documentary, gimbal, and multi-lens production workflows.
Product Overview
NiSi specifies an 18mm focal length, T2.2 to T22 aperture range, ten-blade iris, 46mm image circle, and 0.25m close focus for this Athena Prime. The lens has a PL mount, 0.8 MOD focus gearing, a 300-degree focus throw, fluorescent distance scales, a 77mm front filter thread, and an 80mm outside diameter. The compact 81.3mm length and approximately 800g weight are matched closely to other Athena focal lengths to reduce rig and gimbal changes during lens swaps. The rear filter holder gives crews another place to add compatible ND or diffusion filtration.
Key Features
18mm T2.2 Full-Frame Coverage
The ultra-wide prime covers a 46mm image circle and opens to T2.2, supporting broad establishing views, interiors, architecture, moving-camera work, and close wide-angle perspectives.
Matched Athena Cinema Mechanics
A 300-degree focus throw, 0.8 MOD gearing, fluorescent scales, 80mm front, and dimensions matched to the series support repeatable manual focus and faster lens changes.
Front and Rear Filter Options
The lens provides a 77mm front thread plus a rear filter holder, allowing filtration choices to be planned around the matte box, gimbal, and camera configuration.
How It Compares
Choose the 18mm when an ultra-wide full-frame perspective and matched Athena mechanics suit the shot. Choose the 14mm for a wider view, the 25mm for a more moderate wide-angle perspective and faster T1.9 aperture, or a zoom when rapid focal-length changes matter more than prime-lens consistency.
Compatible Accessories and Related Gear
NiSi Athena Prime 14mm T2.4 PL lens and NiSi Athena Prime 25mm T1.9 PL lens. Use with a camera or adapter built for ARRI PL lenses and an active image area that fits inside the 46mm image circle. Check mount support, rear clearance, rods, lens support, focus motor position, matte-box clamp size, filter plan, and camera crop mode before production.
Who Is This For?
This lens is for cinematographers, camera assistants, owner-operators, rental houses, gimbal crews, and production teams that need an ultra-wide PL prime with full-frame coverage and consistent manual cinema controls.
Who Should Choose Something Else?
Choose a wider 14mm for more coverage, a 25mm or 35mm for less perspective exaggeration, an autofocus still lens when electronic focus is essential, or a zoom when reframing speed matters more than prime-lens size and consistency.
