A proprietary rear filtration system:
The Athena Prime lens series features a Drop-In filter mount, providing greater flexibility and creative control for filmmakers.
The RF- and E-mounts have a Drop-In filter option, while the PL-mount utilizes a rear filter. NiSi also provides a weather sealed for the Drop-In filter.
Note! It´s important to use the Drop-In clear filter on RF- & E-mounts and the rear filter on PL-mount with the lens, to achieve infinity focus and obtain clear images.
All NiSi Athena Prime lenses are similar in weight!
They do not require rebalancing on a gimbal when switching between Athena lenses. All lenses share the same and 77mm filter thread.
Both aperture and focus rings are matched across the range.
All NiSi Athena lenses also have a focus rotation of 300° and fluorescent focus scales, displayed in both imperial and metric units, for precise focus pulls. In addition to their impressive optical performance, the NiSi Athena Cine Lenses are also designed with convenience in mind. The lenses feature a standard 0.8 mod focus and iris gears, making them compatible with a wide range of follow focus and matte box systems.
NiSi 77mm close-up lens can be used to reduce the minimum of focus distance and create great macro effects (sold separately).
