This is a Kenko PRO1 Digital PRO ND4(W) 58mm ND filter. It's an ideal item for those who want to reduce the amount of light when shooting outdoors in bright conditions, or for those who want to control exposure when shooting landscapes or videos. It features an ultra-thin frame design, making it less likely to cause vignetting even when attached to a wide-angle lens. The ND4 type reduces the amount of incoming light to about one-fourth, making it easier to broaden the range of shutter speed and aperture settings even during the day. It's a versatile filter that's easy to use in various shooting scenarios, such as when you want to soften the flow of waterfalls or rivers, or when you want to maintain a constant shutter speed during video recording. It features a digital-compatible multi-layer coating, designed to make it easier to take advantage of the lens's original depiction. It is compatible with 58mm diameter lenses, and it can be attached and removed smoothly. Despite its thin frame, it has a solid construction, and its appearance is neat when attached.
