1000x filter factor, providing a 10-stop exposure reduction which allows you to control depth of field and convey movement more easily Darkens entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required, suitable to record movement/image blur in subjects such as waterfalls, streams, waves, clouds or any fast moving subject It does not affect coloration of the image and is ideal for pairing with other filters, unlike a variable ND filter which could cause "X" cross mark, vignetting, reflections or blur in the picture when using wide angle lenses at higher ND values, this ND1000 fixed 10-stop neutral density 3.0 filter does not have this kind of issue. The filter is constructed from Japanese famous brand optical glass that features 8 layers of anti-reflection coatings on each side(total 16 layers), making the filter anti-scratch, anti-static, oil and water-resistant Compatible with any lens with 77mm diameter filter thread - This ND1000 filter is double threaded, has 77mm inner thread(male) and 77mm outer thread(female), this design allows you to put on any 77mm thread accessories such as lens cap, screw-in type lens hood to the front of the filter This JJC ND filter is a fixed 10-Stop Neutral Density Filter that provides a 10-stop exposure reduction. It allows you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to 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.

Say Goodbye to X cross, vignetting, reflections or blur in the picture which happens on a variable ND filter when use wide angle lenses at higher ND values, a fixed 10-stop ND filter won't have these issues.

It fits for any lens with 77mm filter thread, below are some lenses for your reference:

Why we need a Neutral Density Filter?

-- It enables slow shutter speeds to be used, especially with high speed ISO, to record movement in subjects such as waterfalls, clouds.
-- It decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
-- It decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situation
-- It allows cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure.
