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

NiSi Cine Lens Athena Prime 14mm T2.4 Fuji G-Mount — Ultra-wide T2.4 with Drop-In Filter Option

The NiSi Athena Prime 14mm T2.4 for Fuji G-Mount is part of the Athena Cine Lens series, designed with modern optical technology to serve cinematographers and videographers. This 14mm ultra-wide lens offers a T2.4 maximum aperture and integrates with the Athena system features such as the rear Drop-In filter option for applicable mounts. Use it when you need an ultra-wide perspective and consistent handling across the Athena range.

Key optical characteristics

The Athena series emphasizes consistent light transmission and refined image rendering. For this series, NiSi specifies actual T-stop ratings so you can maintain consistent exposure across the set. In the series:

• 25, 35, 40, 50 and 85mm lenses have a maximum aperture of T1.9 for shallower depth of field and smoother background separation.
• 18mm and 135mm lenses have a maximum aperture of T2.2.
• The 14mm lens has a T-stop of T2.4.

Additionally, the lenses offer ultra-low chromatic aberration and micro-contrast control to preserve fine image detail and accurate color rendition.

Coverage and sensor compatibility

The Athena lenses produce an image circle of 46mm. Therefore, they suit full-frame sensors and can work with larger-format sensors that fall within that image circle. This makes the 14mm Athena lens appropriate for a wide range of camera bodies that accept Fuji G-Mount lenses and meet the image circle requirement.

Mounts and filter system

The Athena Prime series ships in multiple mount options so you can choose the format that matches your camera system. Available mounts in the series include:

• ARRI PL
• Canon RF
• Sony E
• Panasonic/Leica L
• Fuji G

NiSi implements a proprietary rear filtration system on the Athena series. For the RF-, L- and G-Mount lenses the series offers a Drop-In filter option. The Sony E-Mount is available in two versions: one with the Drop-In filter and one without. The PL-mount lenses use a rear filter instead of the Drop-In module.

Important: NiSi states that you must use the Drop-In clear filter on RF-, L-, G- and E-mount versions (when equipped) and the rear filter on PL-mount lenses to achieve infinity focus and obtain clear images.

Also note that the Sony FX9 camera cannot use the E-Mount with Drop-In filters.

NiSi supplies weather sealing for the Drop-In filter to improve protection against the elements when using that filter option.

Handling, focus and consistency across the set

NiSi engineered the Athena primes to make lens changes easier on set. All Athena Prime lenses are similar in weight, which reduces or eliminates the need to rebalance a gimbal when switching lenses within the series. In addition:

• All lenses (except the 14mm) share the same 77mm front filter thread for common front filters and accessories.
• Aperture and focus rings are matched across the range for consistent tactile feel and operation.
• Focus rotation is 300° across the series, and focus scales use fluorescent markings in both imperial and metric units, aiding precise focus pulls under various lighting conditions.
• The lenses use standard 0.8 mod focus and iris gears, so they work with most follow focus and matte box systems.

Minimized focus breathing

NiSi designed the Athena Prime lenses to limit focus breathing. Therefore, when you change focus from the minimum focus distance to infinity, the change in field of view remains very small. This characteristic helps maintain framing during critical focus pulls in narrative and commercial production.

Close-up and macro options

For close-up work, NiSi offers a 77mm close-up lens (sold separately). You can use this accessory to reduce the minimum focus distance and create stronger macro-style effects when you need tight detail shots or dramatic foreground separation.

Technical specifications

Practical use cases

Use the 14mm Athena Prime on wide establishing shots, architecture, and interiors where an ultra-wide perspective helps tell the visual story. Because the Athena series keeps handling and gear positions consistent, you can swap lenses quickly during a shoot and maintain repeatable focus pulls and exposure behavior across focal lengths.

FAQ

Question: Is the 14mm Athena Prime compatible with Fuji G-Mount cameras?
Answer: Yes. The 14mm Athena Prime is offered in Fuji G-Mount as part of the Athena series and supports the Drop-In filter option available for G-Mount lenses.

Question: Do I need to use a Drop-In or rear filter to achieve infinity focus?
Answer: Yes. NiSi specifies that you must use the Drop-In clear filter on RF-, L-, G- and E-mount (when equipped) and the rear filter on PL-mount to reach infinity focus and obtain clear images.

Question: Can I switch Athena lenses on a gimbal without rebalancing?
Answer: You generally will not need to rebalance when switching Athena lenses because NiSi designed the lenses to be similar in weight, minimizing gimbal adjustments during lens changes.

Question: Which lenses share the 77mm front filter thread?
Answer: All Athena Prime lenses in the series share the same 77mm front filter thread except for the 14mm lens, which is the exception noted by NiSi.

Question: Does the Sony E-Mount offer the Drop-In filter option?
Answer: The Sony E-Mount is available in two versions: one with the Drop-In filter and one without. However, note that the Sony FX9 camera cannot use the E-Mount with Drop-In filters.

Question: How does NiSi handle weather protection for Drop-In filters?
Answer: NiSi provides weather sealing for the Drop-In filter to enhance protection against the elements when using that filtration option.

Question: Can I use a close-up lens for macro effects with the Athena primes?
Answer: Yes. NiSi offers a 77mm close-up lens (sold separately) to reduce minimum focus distance and achieve macro-style close-up shots with Athena primes.
