Variable ND Filter 37mm, ND2-ND400 Adjustable Neutral Density Lens Filter

A Variable Neutral Density Filter for Creative Control This 37 mm variable ND filter offers stepless adjustment from ND2 to ND400, giving you considerable flexibility when controlling the amount of light entering your lens. By reducing light without altering colour balance, it allows you to work with slower shutter speeds on high-speed film or digital cameras, making it easier to capture motion blur in waterfalls, clouds or any fast-moving subject. The slim edge design helps prevent vignetting on wide-angle lenses, while the robust aviation-grade aluminium frame provides lasting durability. Optical Quality and Practical Design The filter features eight layers of multi-resistant coating (MRC) to repel water and dust, keeping the surface clean and your images clear. The extra-strong frame is built to withstand regular use and is designed to prevent sticking or jamming when adjusting the ring. By enabling a wider aperture, the filter also helps reduce depth of field, allowing you to separate your subject from the background with greater ease.
