This 58mm Magnetic Quick-Swap Neutral Density 3.0 Filter from Freewell is an ND filter with a 1000x filter factor that provides a 10-stop exposure reduction. The filter's 3.0 density darkens the entire image area without affecting the image's coloration, allowing the photograph to be made with a wider aperture or slower shutter speed than is usually required. Widening the aperture allows for finer control over depth-of-field to help isolate the image subject or increase bokeh. Slowing the exposure time increases blur and conveys movement more easily.

Each surface of the filter is multicoated to help eliminate internal ghosting and reflections. In addition, it features a resistance coating to repel oil, dust, and scratches, offering greater protection to the filter when working on location in harsh environments. The coatings are also hydrophobic, resulting in an improved beading effect when in contact with water or oil for easier cleaning and maintenance. The aluminum filter ring also includes 58mm front threads, permitting the use of screw-on filters with 58mm rear threads.

This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.
