NiSi has introduced two versions of its new Allure Streak Filter, plus a new Pro Nano Natural CPL (circular polarising filter), as well as a new filter holder for Sony’s FE 12-24mm f/2.8 GM lens.
It has released both square and circular versions of the Allure Streak Filter, designed to create a dramatic cinematic anamorphic flaring effect by elongating bright light sources. They are made of optical grade clear glass H-K9L to maintain clarity and quality without affecting the overall colour or contrast. Besides the current blue streak version release, the NiSi Allure Streak filters can also be custom built in other sizes or colours.
The NiSi Allure Streak Filter uses a single series of etched lines spaced 2mm apart running across the filter surface. These can diffract light to create streaks from bright lights or reflections to imitate the effect commonly seen with anamorphic lenses.
The blue Allure Streak Filter creates a streak effect with a blue hue. This further emulates the character of highlights generated when using traditional anamorphic optics.
The filter can be rotated to adjust the orientation of the streak effect, and users can intensify the look of the streaks by bringing the point of light closer to the camera, zooming in, or using brighter light sources. NiSi recommends using a focal length of 35mm or longer with this filter to ensure that the streak effect is straight and not affected by lens distortion.
The square version can be installed in a matte box and rotated 360° and is available in two sizes: 4x5.65-in and 6.6x6.6-in. The circular version has an aluminium frame and a rotatable front, with a thread size of 82mm.
NiSi’s latest circular polariser, the Pro Nano Natural CPL, is designed to reduce glare and reflections on non-metallic surfaces, increase saturation and vibrancy of the sky and foliage while ensuring true colour reproduction. It avoids colour casts and provides more natural colours, especially by removing the warming effect that often results from using other CPL filters.
It uses a proprietary NiSi Pro Nano Coating to help reduce unwanted reflections and provides a waterproof and scratch-resistant layer to assist in the cleaning of fingerprints, dust and water stains. It is available in sizes from 46mm to 95mm.
Also new is the NiSi S6 150mm Filter Holder for Sony’s FE 12-24mm f/2.8 GM zoom lens, which holds two filters and an integrated circular polariser (either the Pro CPL or Enhanced Landscape CPL). It has a newly designed locking wheel to help keep ND filters securely attached and positioned, while the overall build shows no vignetting with the filter holder in an upright position.
