NiSi S6 150mm Filter Holder Kit for Sigma 14mm f/1.8 DG HSM Art- 3-Stage Filter System - Integrated Rotating True Color NC CPL, Holds 2X Size 150x150mm and 150x170mm Filters, Includes Storage Pouch - NIP-FH150-S6-TC-SIG14

• COMPATIBILITY: This S6 model is designed specifically for the Sigma 14mm f/1.8 DG HSM Art lens. The main adapter slips over the lens and secured by twisting the silver collar and tightening the pin. ADAPTER RING: The main adapter is the base of the S6, holding the filter frame and circular filter. It allows for the use of the included CPL, or other S6-specific circular filters (sold separately). TRUE COLOR CPL: The CPL can be threaded to the main adapter and rotated using the gears on either side. It eliminates the yellow cast common in most other polarizers, resulting in truer colors. FILTER HOLDER: The aluminum filter frame can hold up to 2 filters of 150x150mm and 150x170mm size with 2mm thickness. The frame can be rotated 360 degrees and can hold position using the locking pin. PROTECTION: Included is a protection lens cap. After removing the square filter frame, attach the cap to main ring and CPL for front element protection without needing to detach from your lens. NO VIGNETTING OR GLARE: With this S6 model, enjoy clear photos on ultrawide lenses, even when rotating the filter frame. Matting treatment inside the main adapter prevents reflections and flares. STORAGE: Included is a carrying case that fits the whole S6 system components, including a sleeve for a circular S6-specific filter. This allows for easy transportation and safe storage.
