Key Features
- Variable 0.3 to 2.6 Optical Density
- Multi-Coated
- Slim Design
- Darkens Entire Image
This 1- to 8.6-stop, 46mm Blue Multi-Coated Variable ND Filter from K&F Concept is a variable neutral density 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 easily, creating a dynamic look for streams, waterfalls, landscapes, and more. This multi-coated variable neutral density filter does not affect the coloration of the image. The filter's slim design reduces possible vignetting on wide-angle lenses.

I just bought this filter and I experience something weird. When I turn it over the darker ND dot, the filter seems to go even darker and the photo look like a IR shot (all purple). Yesterday I set the filter at his darker point. I took a photo : f.14, 2.5s, iso 100. Then I turn further the filter and it became darker. So I change the time and I hand to go further as 60sec to get proper expose photo.. but in the viewfinder, it was all purple.
Is that normal? I use it on Olympus em10II and 14-42 kit lens
The K&F Concept ND2-ND400 Blue Multi-Coated Variable ND Filter (58mm) is only rated to perform properly till 8.6 stops. Going beyond the specified maximum may degrade image quality. Additionally with higher levels of light reduction one runs the risk of IR pollution in the image. As you reduce visible light you are more suspect to this pollution, which could be why you are seeing the strange colors.
