Designed with professional landscape photographers in mind, this 150 x 170mm Master Series Hard Edge Graduated ND Filter from Benro has a 16x filter factor that provides a 4-stop exposure reduction in selected areas. This specific model features a hard edge in its center that starkly divides the clear section and the darkened section, making it ideal for photos with a sharp horizon such as seascapes and elevated urban landscapes.

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.

Q: 10. i want to purchase this filter please let me know that it is compatible with sony lences if not than which filter system i need to purchase i have 7rm2

A: Amit, to use the filter you have asked about you need to also have the filter holder, and the lens adaptor that are shown. The lens adaptor allows the filter holder to attach to the lens. The lens adaptor you choose must be based on the diameter of lens that you are going to use it on. So if you are going to use it on a 77mm diameter lens then you need to buy the 77mm adaptor similar to the one shown. If you have the correct lens adaptor and the SW150 Mark II adaptor as shown then the filter will be compatible with your lens. Typically the 150mm filter is for use on large diameter wide angle lenses. If yours is not this type of lens then you may want to use the 100mm or 75mm filters and required lens holder and adaptor. Alternatively you can purchase round ND filters that screw directly onto your lens without the need for a filter holder and adaptor, but make sure you order the correct diameter filter. Hope this helps.
