NiSi Athena Prime True Color ND/Polarizer Drop-In Filter

Filtering NiSi Athena Prime

Ultimate versatility with three compatible filter options

1. 77mm Front thread – Attach the NiSi Swift System or any circular filters via a 77mm front lens thread.
2.  Clamp on – Matte boxes can be attached by 77mm screw rings or 80mm clamp-on rings.
3. Tray-mounted drop in filters for E & RF – The rear-mount filter tray for E and RF mount allows you to mount Mist, Streak, CPL, FSND or VND while adding almost no weight to the lens. The real highlight of this is that you can mount two rota filters (one in the rear-mount tray and one 77mm on the front), while keeping the setup incredibly light and compact.
   Screw-in rear mount filters for PL – The PL mounts have an ultra-thin screw thread at the back of the lens, which allows a single filter to be attached. These filters weigh just 10g each, allowing filtration options when you need to keep your rig as small and compact as possible. This can e.g. be a mist at the back, combined with a VND at the front.
