Compatible with filters with thicknesses up to 2mm, the Master Series 170mm Filter Holder from Benro allows you to use several filters simultaneously for stacking their effects. It is designed to fit most ultra-wide lenses without filter threads, and can be used with models that have an angle of view up to 110° without any problems. Alternatively, you can mount the holder normally with the included 95mm mounting ring and 95-77m step-down ring, making it compatible with lenses that have either of those front thread sizes.The Master Series 170mm Circular Polarizing Filter is made to fit the the Benro Master Filter Holder and has a knurled edge for easy polarization adjustment. Adjusting the polarization enables elimination of unwanted glare and reflections on water, glass, and other reflective surfaces. This filter features ULCA multi-coating to render more richly saturated colors, plus NANO WMC protective coating to resist oil, water, smudges, and abrasions when working out on location in harsh environments. It is designed to be used with Benro filter holder system, and even works with ultra-wide lenses. This 170mm filter conveniently slides into the first slot on the filter holder.Designed with professional landscape photographers in mind, this 170 x 190mm Master Series Soft Edge Graduated ND Filter from Benro has an 8x filter factor that provides a 3-stop exposure reduction in selected areas. This specific model features a soft edge in its center, fading gradually from completely clear to darkened as we move towards the top. This allows the filter to keep bright skies under control without creating a line in the image, making it ideal for pictures without a clearly defined horizon line.





The Master Series filters are made with Schott B270 glass and finished with several different layers of coating. These layers increase the resistance of the glass to avoid scratches and help keep the surface waterproof, making it easier to clean when shooting in inclement weather. Additionally, the filter is designed for a neutral performance that avoids affecting color rendition and curtails the unnatural colors found in some pictures with high contrast.The 170 x 170mm Benro Master Series ND Filter has a 16x filter factor that provides a 4-stop exposure reduction. Its 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you can control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.





To prevent internal ghosting and reflections, each glass surface includes multiple layers of antireflection coating. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters. The nano coating associated with Benro Master Series neutral density filters provides an additional 13th layer over each side of this filter, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.
