Variable ND Filter with high-quality coating: The Walimex pro ND2-ND400 Fader Slim Super DMC with a diameter of 49 mm is a variable neutral density filter, also known as an ND filter, designed for demanding use in photography and videography. The ND filter is compatible with all common camera lenses and video lenses—what matters is the correct filter diameter (here 49 mm). The lens filter flexibly and continuously reduces incoming light by up to 9 stops. It is ideal for those who want to work flexibly under changing lighting conditions without having to change filters. Thanks to the 18-layer Super DMC coating, the filter is particularly scratch-resistant, dirt-repellent, and nearly reflection-free—perfect conditions for sharp images in any lighting situation. Slim design for wide-angle lenses: The slim frame of the ND filter, only 4.3 mm high, allows for use with wide-angle lenses without causing vignetting or dark edges in the image. This makes this neutral density filter especially suitable for creative perspectives in landscape, architecture, or city photography. The robust yet delicate construction makes the camera filter an ideal companion for any camera equipment. Applications of the neutral density filter in photography: The ND filter is versatile: for long exposures in daylight, it creates smoothly flowing water surfaces, moving clouds, or deserted places through motion blur. In portrait photography, the ND filter allows for the use of large apertures in bright ambient light, resulting in shallow depth of field with beautiful bokeh. In videography, the neutral density filter also helps to avoid overexposure in bright lighting conditions. The variable light reduction range of the filter allows for optimal adjustment to the respective conditions—completely without changing filters.
