KENKO Variable ND Variable NDX Variable Detachable Light Intensity Neutral Gray 673058 Filter, II, 72mm, Density, ND2.5-ND450, Lever, Adjustment,

[Variable ND filter with improved color neutrality thanks to the use of a new polarizing film] This variable ND filter uses a new polarizing film that improves color neutrality, enabling you to capture natural colors. [A wide range of light-reduction effects with just one lens.] The density can be adjusted continuously from ND2.5 to ND450 (at a focal length of 50mm). [You can use your existing lens cap!] With typical variable ND filters, the diameter of the lens attachment and the filter thread on the front of the filter change (the filter becomes one size larger) due to their structure. However, like other lens filters, this product does not change the filter diameter when attached, so you can continue to use your existing lens cap. [Includes a detachable control lever. Optional installation position] The filter comes with a control lever for adjusting the density. You can choose from two installation positions, which is useful when shooting video. ■Usable density range (all values converted to 35mm format): 24mm focal length → up to ND40 / 35mm focal length → up to ND80 / 50mm or longer focal length → up to ND450. *Density variations may occur if the above densities are exceeded.
