Variable ND Filter 49mm, ND2-ND400 Adjustable Neutral Density Lens Filter

A Variable Neutral Density Filter for Creative Control This 49 mm variable ND filter gives you stepless control from ND2 to ND400, letting you dial in exactly the right level of light reduction without affecting colour balance. The adjustable ring rotates smoothly between the two extremes, so you can fine-tune exposure quickly as conditions change, rather than carrying a set of fixed filters. Designed for Long Exposure and Shallow Depth of Field By cutting the light entering your lens, the filter allows slower shutter speeds even on fast film or digital cameras. That makes it ideal for capturing the silky movement of waterfalls, drifting clouds or any fast-moving subject with attractive motion blur. At the other end of the scale, the wider aperture you can use helps reduce depth of field, making it easier to separate your subject from a busy background. Built to Perform Outdoors The slim profile keeps the filter unobtrusive on wide-angle lenses, helping to prevent vignetting at the edges of the frame. An eight-layer multi-resistant coating repels water and dust, while the robust aviation-grade aluminium frame is built to withstand regular use and resist sticking or jamming when you adjust the ring.
