Take your photography to the next level with the K&F; Concept 49mm Nano-X ND2-32 1-5 Stop Magnetic Variable Neutral Density Lens Filter. This innovative filter is designed to extend exposure time, allowing you to capture every breathtaking moment with precision and clarity. The K&F; Concept Magnetic Variable ND filter is engineered to reduce the amount of light entering your camera lens. This key feature makes it easier to achieve professional effects such as a shallower depth of field or blurred motion. With its 1-second swap feature, there's no need to screw on the lens, ensuring you never miss a shot. This neutral density filter offers adjustable light reduction from 1 to 5 stops. Simply rotate the filter to control the light reduction, giving you the flexibility to adapt to various lighting conditions. Designed to support wide-angle lenses without vignetting, the front diameter of this filter is larger than the back diameter, ensuring optimal image quality. The K&F; Concept 49mm Nano-X ND2-32 filter allows the use of slow shutter speeds with high-speed films or digital cameras, enabling you to record movement and image blur in your subjects. It also helps decrease the depth of field by using wider apertures, effectively separating subjects from their background. Featuring K&F; Concept's self-lock frame technology, this filter locks in place while rotating to the minimum (ND2) or maximum (ND32) setting. This unique feature helps wide-angle lenses avoid the dark "X" cross in photos, ensuring crisp, clear images every time. With 5 stops of light reduction including ND2, ND4, ND8, ND16, and ND32, this filter is suitable for a variety of scenes and is particularly recommended for landscape photography. Its ultra-slim frame, at only 7.4mm thickness, effectively avoids vignetting even on wide-angle lenses. Both sides of the filter feature a nanometer coating, making it waterproof and scratch-resistant. This reduces reflections from the filter itself, without negatively affecting image quality.
