Benro Master Series Filter (77mm, 6-Stop)
Key Features
  • 1.8 Optical Density
  • Multi and Nano Coatings
  • Brass Filter Ring
  • SCHOTT B270 Glass Construction
The 77mm Benro Master Series ND Filter has a 64x filter factor that provides a 6-stop exposure reduction. Its 1.8 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.

Benro ND Filter Overview

The 77mm Benro Master Series ND Filter has a 64x filter factor that provides a 6-stop exposure reduction. Its 1.8 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.

This filter is constructed from SCHOTT B270 glass for increased optical clarity as well as color fidelity and features a brass filter ring for enhanced durability and to prevent jamming .

Benro 150 x 150mm Master Series

I recently purchased the Master 150mm Filter Holder Kit for Lenses with 95mm, Master Series Lens Ring for FH150T1 Filter Holder, and 150 x 150mm Master Series ND 1.8 Filter (6-Stop) prior to leading a photography session in Maine for the week of October 16th. The kit was used in conjunction with a newly purchased Tamron 15-30mm ultra-wide lens.  The Benro filter system generated a lot of interest and excitement from other photographers throughout the trip. I purposefully withheld my comments until I had the opportunity to field test the hardware for the duration of the weeklong trip.  First let me preface my comments by stating that my application was exclusively landscape photography. While my experience regarding the quality of the filters themselves was very positive, I have serious concerns with the overall design of the system and its practical use in the field. First, with respect to the CPL, I am not a fan of having the CPL as a permanent filter in the system. Given the current design, it would not be practical to swap the CPL in and out in the field given the need to remove and reinstall the rails when doing so (granted the polarizing affect can to dialed in or out depending on the image one in trying to capture). At times I did not find the CPL very fluid in its ability to rotate when used in conjunction with additional filters in the system. In addition, one of the CPL thumb wheels is often restricted when used in concert with the GND filter. Given the narrow tracks in the system, there is also the constant concern of scratching the filters, particularly with respect to the spacing between CPL and the first filter.  I found the Filter Holder to be the Achilles heel of the filter system. Of major concern are the tracks used to accommodate the additional filters. I found it very difficult to insert filters into the tracks. There was nothing fluid or effortless in inserting the filters into the tracks. Once initially inserted in the track, the filter would typically become jammed as it attempted to navigate and align with the lower section of the track. I often found myself needing to depress the leading edge of the filter inward in order to ensure the filters alignment within the lower portion of the track. Consequently, the resistance offered by the tracks, when attempting to insert the filter when mounted to the camera on a tripod, was often sufficient to vary the camera’s position on the tripod. This would often alter the composition of the image one was attempting to take, thus requiring the need to recompose the image. In summary, I did not find the design of the filter system as functional or practical for use in the field. The system presented as a particular source of frustration when operating in the dark or in other adverse conditions. I often found myself defaulting to inserting filters in the filter holder prior to mounting the system on my lens in an attempt to avoid the above-mentioned issues, thus rendering the system as very inflexible.  Given the overall cost of the filter kit and the individual filters, I must conclude that the system failed to meet my expectations. In my opinion, the filter holder needs to undergo a major redesign to address the above-mentioned issues and deliver a system that meets the superior quality of the Benro filters themselves. Consideration should be given to a redesign that offers a fluid track system allowing for easy/safe insertion and removal of the filters, provides easy access and rotation of the CPL when using multiple filters, and the option of using the CPL in any given situation.  Prior to authoring my review, I reached out to Benro on several occasions for comment both by email and phone. To date, I have not received a response to my attempts to solicit a response.

Will this fit the Nisi 75mm filter holder?

Will this fit the Nisi 75mm filter holder?
Asked by: Christopher
If the holder works with 75x75mm filters then yes you can use this in it. This should work with any 75x75 Filter Holder.
