Rent NowThe RED PRO PRIME 18mm T1.8 Lens (PL Mount) is a wide-angle cinema prime lens built for RED Digital Cinema cameras, engineered to deliver crisp, high-resolution images that complement RED’s professional cinema camera lineup, including the RED ONE, EPIC-X, DRAGON, and SCARLET-X. It’s part of RED’s Pro Prime family, positioned as an accessible alternative for productions that need PL-mount cinema glass without the budget for lenses like Zeiss Master Primes or Ultra Primes.
Optically, the lens offers an 18mm focal length with a T-stop range of T1.8 to T22, using the latest optical design in the Pro Primes line to produce impressive contrast and color reproduction that rivals higher-end cinema primes, with virtually no focus breathing even at the lens’s fastest T1.8 aperture. The lens features a 110mm front diameter, consistent across the entire Red Pro Prime set, allowing filmmakers to use the same matte box and filter accessories without readjustment when swapping between focal lengths in the lineup. A notably close minimum focus distance of 4 inches gives the lens added versatility for tight, dramatic wide-angle compositions.
As a PL-mount cine lens, the 18mm Pro Prime uses geared focus and iris rings designed for standard follow-focus systems common in professional film and video production, rather than autofocus or electronic aperture control, giving cinematographers precise, repeatable manual control over both focus and exposure. Because this lens has an extended flange design, it is not compatible with some shutter-based film cameras or certain digital cinema camera bodies, so photographers and rental houses should confirm mount compatibility with their specific camera before use.
Build quality reflects RED’s Pro Prime construction standards, with the lens weighing approximately 6.45 lbs, giving it a substantial, well-balanced feel suited to professional rigs. The lens is typically sold and used as part of a matched set alongside other RED Pro Primes (commonly 18mm, 25mm, 35mm, 50mm, 85mm, and 100mm, all sharing the same T1.8 maximum aperture and 110mm front diameter), and comes with front and rear element caps.
