Kenko Variable ND Variable NDX Adjustable Density Detachable Lever Neutral Gray Polarizing 673058 Filter, II, 72mm, (ND2.5-ND450), Included, Film,

[Variable ND filter with enhanced color neutrality thanks to a new polarizing film] This variable ND filter features a new polarizing film that improves color neutrality, enabling natural-looking color reproduction in your photos. [A single lens provides a wide range of light-reducing effects.] The ND2.5 to ND450 (at a focal length of 50mm) density can be adjusted steplessly. [You can use your existing lens cap!] While typical variable ND filters change the lens mounting diameter and the front filter thread diameter due to their structure (making them one size larger), this product, like other lens filters, does not change the filter diameter when attached, so you can use your existing lens cap. [Detachable control lever included. Multiple mounting positions available.] A control lever for adjusting density is included and can be attached to the filter. With two mounting positions to choose from, it's very convenient for video shooting. ■Approximate usable density range (all in 35mm equivalent): 24mm focal length → up to ND40 / 35mm focal length → up to ND80 / 50mm focal length and above → up to ND450. *Exceeding the above densities may result in uneven density.
