Compact 55mm ND Filter for Sony A7IV, A7III, A7II, A7 & Nikon D5600, D3500, D3400 Cameras

The variable neutral density (ND) filter is designed with a built-in rotating ring that controls neutral density ranging from ND2 to ND2000 (1 to 11 f-stop), eliminating the need to buy many fixed ND filters. This feature allows you to photograph with a wider aperture or slower shutter speed than normally required, suitable for recording movement or image blur in subjects such as waterfalls, streams, waves, clouds, or any fast-moving subject.

The filter is constructed from German-made optical glass featuring 9 layers of anti-reflection coatings on each side (a total of 18 layers), making it anti-scratch, anti-static, and oil and water-resistant. This high-quality construction ensures excellent image quality and durability.

The variable ND filter is compatible with any lens with a 55mm diameter filter thread. It has a double-threaded design, with a 55mm inner thread (male) and a 58mm outer thread (female), allowing you to attach 58mm thread accessories, such as a lens cap or screw-in type lens hood, to the front of the filter.

However, when using this variable ND filter at high ND values (9 f-stop or above) on wide-angle lenses, you may encounter issues such as a "X" cross mark, vignetting, reflections, or blur in the picture. This is an unavoidable consequence of the structure and operating principle of a variable ND filter. If this is not acceptable to you, it is recommended to use a non-variable ND filter, such as the popular JJC brand fixed ND1000 10 f-stop ND filter.

The heavier the density of the variable ND filter, the slower your shutter speed will be, allowing you to capture motion blur and other creative effects. This feature is particularly useful for photographing subjects that require a slower shutter speed, such as waterfalls, streams, waves, and clouds.

In summary, the variable ND filter offers a convenient and versatile solution for photographers, providing a wide range of neutral density control without the need to carry multiple fixed ND filters. However, users should be aware of the potential drawbacks when using the filter at high ND values on wide-angle lenses and adjust their expectations or choose a non-variable ND filter if necessary.
