NiSi Cine Filter FS ND 2.1 (7 Stop) for Athena PL-Mount Lenses

NiSi Cine Filter FS ND 2.1 (7 Stop) – Full Spectrum Rear PL Filter for ATHENA PL Lenses

NiSi Cine Filter FS ND 2.1 (7 Stop) er et fullspektret nøytralfilter med bakmontert PL-design laget spesielt for NiSi ATHENA PL‑fatningsobjektiver. Det reduserer innkommende lys med syv blendertrinn samtidig som fargegjengivelsen bevares, og gir presis kontroll over eksponering og dybdeskarphet. Filteret monteres på baksiden av ATHENA PL‑objektiver og leveres med et sugekoppverktøy som gjør det enkelt å bytte filter uten å etterlate fingeravtrykk.

Key features

• Superior light management: The FS ND 2.1 reduces light entering the lens by precise stops. As a result, you can use slower shutter speeds and larger apertures to achieve cinematic motion blur or increased depth of field control, even in bright conditions.
• Full spectrum capability: The filter is designed to maintain fidelity across the color spectrum, avoiding color shifts so your footage requires minimal colour correction in post.
• Custom-fit for ATHENA PL lenses: This is a rear‑mounted filter tailored specifically for NiSi ATHENA PL Mount Lenses, ensuring proper alignment and consistent image quality.
• Included suction cap tool: The filter ships with a tool that features a suction cap design. This tool lets you swap filters quickly and helps prevent fingerprints on optical surfaces during changes.
• Built to last: The filter uses premium optical materials with a Multi Ti Nano coating. Consequently, it offers low reflection and anti‑scratch resistance suitable for professional use.

Benefits and use cases

Bruk NiSi FS ND 2.1 når du trenger å kontrollere eksponeringen uten å endre blender eller lukkertid drastisk. For eksempel kan filmskapere beholde en stor blenderåpning for liten dybdeskarphet eller velge en langsommere lukkertid for naturlig bevegelsesuskarphet når de arbeider i sterkt dagslys. Fullspektret design bevarer nøyaktige farger, noe som reduserer tiden brukt på fargekorrigering.
