NiSi Cine Lens Athena Prime 14mm T2.4 PL-Mount

NiSi Cine Lens Athena Prime 14mm T2.4 PL-Mount — Ultra-wide 14mm T2.4 with rear filter for PL systems

The NiSi Athena Prime 14mm T2.4 in PL mount delivers an ultra-wide-angle option within the Athena cine lens series. It shares the same optical and mechanical design language as the rest of the Athena Primes, making it a coherent choice when you work across the set. This 14mm lens is built to integrate with professional PL-mount workflows and uses a rear filter system specific to the PL version.

Wide focal range and consistent exposure

The Athena Prime series spans focal lengths from 14mm ultra-wide to 135mm portrait, covering super-wide angle through portrait lengths. This range gives filmmakers flexibility for many shooting scenarios and lets you capture a wide variety of subjects without changing lens families.

The lenses use T-stop ratings to describe actual light transmission. That approach ensures consistent exposure across the set when you match lenses by their T-stops during production.

Max apertures in the series

The series offers different maximum T-stops depending on focal length. Several mid-range primes share a fast T1.9, which helps create shallow depth of field and pleasing background separation. Other focal lengths have slightly smaller maximum T-stops while maintaining consistent transmission numbers for reliable exposure control.

Optical coverage and image quality

NiSi specifies an image circle of 46mm for the Athena Primes. This coverage makes the lenses suitable for full-frame cameras and even many large-format sensors. The optics emphasize ultra-low chromatic aberration and micro-contrast control to render finer image details across the frame.

The lenses are designed to minimize focus breathing. In practice, this means the change in field of view when you pull focus from close focus distances to infinity remains extremely small, which benefits controlled focus pulls in narrative and commercial work.

Filter system and mount options

The Athena Primes include a proprietary rear filtration concept. PL-mount lenses utilize a rear filter. RF-, L- and G-mount lenses offer a Drop-In filter option. The E-mount is available in two versions: with and without the Drop-In filter. NiSi supplies weather sealing for the Drop-In filter to protect the filter assembly in mixed conditions.

• Sony FX9 cameras cannot use the E-Mount version with Drop-In filters.
• To achieve infinity focus and clear images: use the Drop-In clear filter on RF-, L-, G- and E-mounts, and use the rear filter on PL-mount lenses.

Mechanical consistency and on-set workflow

NiSi matched aperture and focus ring positions across the series. All Athena Primes share a similar weight, so you do not need to rebalance a gimbal when switching lenses within the line. These design choices reduce downtime and help maintain a consistent handoff between camera setups.

Except for the 14mm lens, all Athena Primes share a 77mm front filter thread. Focus rotation is 300° across the range, which gives fine control for precision focus pulls. Scales on the lenses are fluorescent and display both imperial and metric units for repeatable marks under low light.

The lenses use standard 0.8 mod focus and iris gears, making them compatible with common follow focus and matte box systems found in professional rigs.

Accessories

NiSi offers a 77mm close-up lens (sold separately) that reduces the minimum focus distance for macro-style shots. This accessory gives you greater close-focus capability without changing lenses on set.

FAQ

Question: Can I use a Drop-In filter with all mounts?

Answer: RF, L and G mounts offer a Drop-In filter option. E-mount is available in two versions—one with and one without Drop-In. PL-mount uses a rear filter instead of a Drop-In option. Use the correct filter type to achieve infinity focus.

Question: Will switching between Athena lenses affect gimbal balance?

Answer: No. All Athena Prime lenses are similar in weight, so you do not require rebalancing when changing lenses within the series.

Question: Does the 14mm share the same front filter thread as the other lenses?

Answer: No. All Athena Primes except the 14mm share a 77mm front filter thread. The 14mm uses a different arrangement and the PL-mount uses a rear filter.

Question: Is focus breathing controlled?

Answer: Yes. Athena Primes have been designed to minimize focus breathing, keeping changes in field of view very small when you adjust focus from close distances to infinity.

Question: Are follow focus and matte box systems compatible?

Answer: Yes. The lenses use standard 0.8 mod focus and iris gears, and the aperture and focus rings are matched across the range for consistent use with follow focus systems and matte boxes.
