This 4-stop, 100 x 150mm X-PRO Square Reverse Graduated ND Filter with Frame from K&F Concept is made for the X-Pro Square Filter Holder System. This reverse graduated filter allows a selective area of density to be added to an image, making it an essential tool for enhancing landscape images. This filter's reversed soft edge tapers off to darken the selective area of the image by four stops, and it is well suited to darkening sunrises and sunsets for more saturated, impactful images.

Made of high-quality optical glass, this 100 x 150mm, 2mm thick filter features 28 layers of multicoating for optimal light transmission without adding any color cast. The coating also protects the filter from water, oil, minor scratches, and abrasions. It features a protective frame with large tabs that make it easy to install and remove from the X-Pro filter holder system.

Q: 4. Can I use a this filter for a Canon 24-105mm and Sigma 18-35mm lens?

A: Yes, but you need one more part to make it fit. You'll need what's called a step-up ring. Your Canon lens is a 77mm filter thread size and you need a step-up ring (super cheap to buy) that spans the difference (a 77mm to 82mm ring). Same for Sigma - need to find a 72-82mm step-up ring or you may have to buy two, a 72-77mm and a 77-82mm. You can shop for them here.

Q: 6. does this affect colors in any way? does it desaturate colors as those cheaper ND filters?

A: Hi my friend, this is a nice piece of glass, for Shure you will have some impact in your color results. Minors, but they will be there. No free lunch. To be a variable in one piece you sacrifice something. Specially because it is affect the luminance that is very very important to color. But don't worry, you can easily fix at post, for video or photography. Best

Q: 8. How can we clean the inside of the filter?

A: I must admit in a career of photography never needing to clean the inside of a rotating Polarizer. If for some really reason you actually had to clean the inside, that would be a task for a professional camera technician. No user serviceable parts are here.

Q: 9. When stopped to the highest setting (5 stops) does the image degrade (sharpness, cross hatching)?

A: I've shot extensively with the 95mm, 72mm, & 67mm versions. You don't get any cross-hatching, but a definite vignette in the corners toward the 5 stop range when shooting photos. Video is not an issue as it crops to 16:9. Other than than, negligible colour cast & no sharpness issues.
