[An essential for video shooting! Variable ND filter for instant brightness adjustment] This variable density ND filter allows you to instantly adjust for significant changes in brightness during a single shoot, or for the difference in light levels that occur when changing scenes during video shooting. [Improved flatness leads to increased resolution!] Compared to the previous model (PRO1D Smart Variable NDX), the resolution has been increased by further improving the flatness of the glass. [Smooth operation up to ND32!] When using a lens with a focal length of 24mm, it can be used without X-shaped unevenness up to the equivalent of ND32. (This may vary depending on the focal length of the lens used.) [Water- and oil-repellent coating repels dirt!] This product features a reliable water- and oil-repellent coating, making it ideal for outdoor photography. Water and dirt can be quickly wiped away. ■Filter diameter: 49mm (lens mounting side) / 52mm (lens cap mounting side) ■Country of manufacture: Japan
