Benro Master Glass Drop-in Filters

Benro Master Glass Drop-in Filters deliver the finest quality, color accuracy and sharpness of any filters currently on the market. Our drop-in filters are available in soft and hard-edge graduated neutral density, reverse graduated neutral density and solid neutral density. They are designed for use in 75, 100, 150 and 170mm filter holder systems. We also produce polarizers for each of these filter holder systems, to use together with our drop-in filters.

Every Benro Master Filter is made with Schott B270 German optical glass, due to its superior optical performance, high light transmission and color accuracy. High Definition Optical Technology results in precisely ground optical glass, ensuring that opposing filter surfaces are perfectly parallel to one another, and that the light entering the lens passes through the filter to the sensor in a straight line, which is absolutely essential for maximum sharpness and ghost-free imagery. We test every filter by hand to ensure it meets the rigorous standards required of all Benro Master Filters.

To prevent any color shift caused by infrared light pollution, a proprietary IR Cut coating is applied to all Benro Master Filters which blocks infrared light waves before they can reach the camera sensor. ULCA Multi-Coatings decrease flare while reducing chromatic aberrations (average transmission >99% @ 420-680nm). Black Edge Coatings help prevent internal reflections and optical flare.

Benro’s Waterproof Multi-Coatings (WMC) are clear, neutral coatings that provide a smooth, anti-scratch protective coating to the optical surface, for an extra measure of protection, with no effect on image clarity. WMC coatings also repel water, fingerprints, and smudges and make it much easier to remove dirt and smudges that do manage to adhere to the filter surface.

By every standard, we believe Benro Master glass drop-in filters outperform the competition. And when it comes to choosing a filter holder system to use them in, we think you’ll find Benro’s Master filter holders to be the most thoughtfully designed, meticulously constructed and easiest and most intuitive to use.

Benro Universal Resin Drop-in Filters

Benro Universal resin drop-in filters are a budget-friendly way to introduce a photographer to the creative potential of drop-in filters. Our resin drop-in filters are available in soft and hard-edge graduated neutral density, reverse graduated neutral density and solid neutral density and are designed for use in 100 and 150mm filter holder systems. We also produce glass polarizers for each of these filter holder systems, to use together with our drop-in filters. Although resin doesn’t offer the same sharpness, clarity or transmission properties of glass filters, our resin filters deliver an excellent balance of performance and cost.

Benro Universal resin drop-in filters are made with PMMA resin, hard-wearing shock-resistant material perfectly suited to heavy extended use. A cost-effective alternative to glass filters, these filters are a great fit photographers eager to learn new techniques and improve their photographic skills. Resin filters are generally more susceptible to scratches and marks than glass filters, but can be dropped or bent without breaking.

Benro’s advanced dyeing technology reduces the issues of color shift found with other resin filters, resulting in improved neutrality of our resin coatings.

Benro’s Waterproof Multi-Coatings (WMC) are clear, neutral coatings applied to each filter, providing a smooth, anti-scratch protective coating to the optical surface, with no effect on image clarity. WMC coatings also repel water, fingerprints, and smudges and make it much easier to remove dirt and smudges that do manage to adhere to the filter surface.

Although resin filters are more susceptible to warping or scratching over time, they are perfect for heavy use in the field and in challenging conditions. They are far less likely than glass to crack or shatter, and should they become badly marked after extensive use, are relatively inexpensive to replace.

Master Series Glass Filters

Benro’s Master Series Glass Filters have been created to offer the finest quality and optimum clarity of any filters currently available. Optical quality glass is imported from German glass-maker Schott, before being finished with proprietary coatings formulated specifically to meet our exacting standards for color neutrality. We test every Master Series filter by hand to ensure it meets the optical qualities required to be called a Master Series Filter.

German Schott Optical Glass has been selected due to its superior optical performance, high light transmission and stable optical properties. In order to reduce reflections on the surface of our filters, and to prevent glare occurring between the lens and filter, Master Filters are given a special reflection absorption coating. This reduces the reflection properties of our filters to less than 1.5%.

In order to reduce the redish – orange color shift in images, which can be caused by infrared light pollution, Benro Master Series Filters are coated with an anti-reflection treatment. This bespoke coating cancels out infrared light waves before they can enter the camera sensor. Our advanced coating technology neutralises Infrared light waves resulting in ultra low color shift and high light transmission.

A waterproof, multi-layered (nano) coating with anti-scratch protection is applied to all Master Series Glass filters. By adopting the most advanced, ultra smooth WMC technology on the surface of each Master Filter, they are protected from almost everything nature can throw at them, with no effect on the clarity of images captured. The hydrophobic qualities of the coating keep the surface free of dust, oils and liquids and make the filters highly scratch resistant.

High Definition optical technology has resulted in a precisely ground optical glass, which ensures that filter surfaces are clear and parallel. Perfectly balanced surfaces allow light entering the lens to do so evenly, maximizing image capture quality and light transmission through the filter. A special ultra-low chromatic aberration clear coating prevents light reflection and improves light transmission, resulting in better quality images.

Universal Series Resin Filters

Benro Universal Series filters are available in 100mm and 150mm size options. Offering a varied selection of Hard, Soft, Reverse and Neutral Density graduations, Benro resin filters are a budget friendly way of experimenting with filters in photography. Although Resin doesn’t offer the same sharpness, clarity or transmission properties of Glass filters, our resin filters do offer a quality beyond that offered by competitors in the market.

The PMMA Resin used in the Benro Universal Series filter is a hard-wearing shock-resistant material, perfectly suited to heavy extended use. A cost-effective alternative to glass filters, perfect for photographers that are keen to advance their photographic skills. Resin filters are generally more susceptible to scratches and marks than glass filters, but can be dropped or bent without breaking. Precision ground resin creates parallel surfaces, allowing the light entering the lens through the filter to do so evenly.

Advanced dyeing technology reduces the issues of colour shift found with other resin filters. Benro Universal Series filters are able to guarantee Low Colour Shift through digital colour comparisons (in testing) resulting in improved neutrality of resin graduation coatings.

A waterproof multi-layered (nano) coating is applied to filter surfaces to create an ultra-smooth, hardened anti-scratch finish. The clear coating will repel dirt and liquids and will also allow for quick easy cleaning of the filter surface.

Although Resin filters are more susceptible to warping or scratching (over time) they are perfect for heavy use in the field, or in challenging conditions. They are far less likely than glass to crack or shatter if dropped, and should they become badly marked after extensive use, are relatively cheap to replace.
