This 1- to 8.6-stop, Variable Fader ND2-ND400 Filter from K&F Concept is a 43mm filter providing an adjustable light reduction of 1 to 8.6 stops. It darkens the entire image evenly, allowing a photograph to be made with a wider aperture or slower shutter speed without overexposing your image. By slowing the exposure time or increasing the aperture, it is possible to control the depth of field and blur movement, creating a dynamic look for streams, waterfalls, landscapes, and more.

The rotating filter ring is made from aircraft-grade aluminum and features a density scale and 46mm front filter threads.

Q: 5. Is it MIJ?

A: Hi, assuming MIJ means Made In Japan - I think Pentax now produce their lens in Vietnam, that said, the FA series are superb quality.Mine (Vietnam) is flawless.The specs are supposed to be the same. It's ridiculously sharp even wide open, and i'm not talking about just the center of the image. It's very reliable as there's no internal motor and the construction is all metal. AF is also spot on, so I highly recommend it, especially for low-light shooting!
