NiSi Cine Lens Set Athena Prime Fuji G-Mount (Without Drop-In Filter)

NiSi Cine Lens Set Athena Prime Fuji G‑Mount – 5 primes (14mm–85mm) without Drop‑In filter

This NiSi Athena Prime kit for Fuji G‑Mount gives filmmakers a matched set of five prime lenses that cover ultra‑wide to portrait focal lengths. The kit delivers consistent T‑stop performance across the included primes, matched gearing and weight balance for practical use on rigs and gimbals, and a hard case plus cinema filters to support professional workflows.

Designed for versatile cinematic shooting

The Athena Prime series spans focal lengths from 14mm up to 135mm across the full family, offering coverage from super‑wide angle to portrait lengths. The NiSi Athena Cine Lens Set in this listing contains five specific G‑Mount primes that handle most filmmaking situations, from wide environmental shots to tight portraits.

Consistent light transmission and aperture control

NiSi specifies the T‑stop for each lens so you get reliable exposure across the set. In this kit, the 25mm, 35mm, 50mm and 85mm lenses share a maximum aperture of T1.9 for shallow depth of field and pleasing background separation. The included 14mm lens has a maximum aperture of T2.4. Across the broader Athena range, NiSi notes that 18mm and 135mm lenses have maximum apertures of T2.2.

Optical coverage and image quality

The Athena primes produce an image circle of 46mm, making them suitable for full‑frame and large‑format sensors. NiSi also highlights ultra‑low chromatic aberration and micro‑contrast control throughout the series, which contributes to finer image detail and consistent color rendering.

Mechanical design and cinema compatibility

• All Athena primes have a 300° focus rotation for precise focus pulls and smoother transitions.
• Fluorescent focus scales are marked in both imperial and metric units for clarity on set.
• Both aperture and focus rings are matched across the range, simplifying lens swaps during a shoot.
• The lenses use a standard 0.8 mod focus and iris gear, making them compatible with most follow focus and matte box systems.
• All lenses in the series are similar in weight, so you typically do not need to rebalance a gimbal when switching between Athena lenses.
• All lenses except the 14mm share a 77mm front filter thread.

Rear filtration and Drop‑In options

The Athena Prime family features a proprietary rear filtration system. For the different mounts NiSi offers:

• RF, L and G mounts have a Drop‑In filter option.
• E‑Mount lenses will be offered in two versions: with and without a Drop‑In filter.
• PL‑mount lenses use a rear filter solution.

NiSi also supplies a weather seal for the Drop‑In filter. Note that you must use the Drop‑In clear filter on RF, L, G and E mounts (when applicable), and the PL rear filter on PL lenses, in order to achieve infinity focus and obtain clear images.

Important compatibility note: The Sony FX9 camera cannot use the E‑Mount version equipped with Drop‑In filters.

Accessories and optional macro capability

NiSi offers a 77mm close‑up lens that can reduce minimum focus distance and create macro effects; this close‑up lens is sold separately and attaches to the shared 77mm filter thread on lenses that have it.

Usage and compatibility tips

When you use Athena lenses with Drop‑In or rear filters, install the clear Drop‑In or rear filter as required to reach infinity focus and optimal image clarity. The matched weight and gearing make lens swaps faster on set and reduce the need to rebalance stabilizers when changing primes. Finally, remember the Sony FX9 is not compatible with the E‑Mount version that includes Drop‑In filters.

FAQ

Question: Will I need to rebalance my gimbal when switching between Athena lenses?
Answer: No. All NiSi Athena Prime lenses are similar in weight, so you generally do not need to rebalance when changing lenses within the series.

Question: Do the G‑Mount lenses in this kit include Drop‑In filters?
Answer: These specific G‑Mount lenses in the kit are listed "Without Drop‑In Filter." The Athena series does support a Drop‑In system for G‑Mount, but this kit does not include the Drop‑In filters installed.

Question: Can I use the included lenses on full‑frame or large‑format cameras?
Answer: Yes. The Athena lenses have an image circle of 46mm, which NiSi specifies as suitable for full‑frame and large‑format sensors.

Question: Is there a weather seal for the Drop‑In filter?
Answer: Yes. NiSi provides a weather sealed solution for the Drop‑In filter to help protect the rear filtration area.

Question: What should I do if I need macro capability?
Answer: NiSi offers a 77mm close‑up lens (sold separately) that reduces minimum focus distance to create macro effects on lenses that have the 77mm front filter thread.
