The 130 x 170mm, 2-stop Cokin NUANCES X-Pro ND Filter 130x170mm 2-Stopis designed for use with a Cokin X-Pro Series Filter Holder. It can be applied to darken the sky, specifically along the horizon during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image.

This filter achieves its effect with a 0.6 band of density across its center region that provides up to a 2-stop reduction in light from entering a lens. The band of density extends approximately 1.6" in both vertical directions before tapering to clear below and above with soft-edged lines of transition before the clear areas. The clear areas then extend approximately 2.6" until they meet the top and bottom edges of the filter.

A narrow 0.6 band of density with larger clear areas directly above and below it allows the Cokin NUANCES Extreme X-Pro Series Center-Graduated Neutral Density 0.6 Filter to specifically match the positioning of the sun when it is at, or immediately above, the horizon. In such instances, the sun will appear closer to the center of an image as opposed to the upper edge, and an increase in brightness is created which is much more prominent on both sides of the sun than either above or below it. This pattern of brightness corresponds to the density pattern on the Cokin NUANCES Extreme X-Pro Series Center-Graduated Neutral Density 0.6 Filter. The soft-edged lines of transition in this filter are useful for images that have features alongside the sun that cannot be confined within the band of density.

Cokin NUANCES Extreme filters are constructed from tempered, shock-resistant glass and feature nano-metallic alloy film coatings on both sides of the filter surface to attenuate infrared light while maintaining true color fidelity, even when stacked with other Cokin NUANCES or NUANCES Extreme filters. Anti-glare coatings further help to reduce surface reflections for increased contrast and clarity, while additional hydrophobic coatings result in an improved beading effect when in contact with water for greater cleaning efficiency. Additionally, Cokin NUANCES Extreme filters feature C-shaped edges. This rounded edge shape resists chipping to further enhance durability.

• This filter is compatible with a X-Pro Series Filter Holder.
• Effectively darkens skies, specifically along the horizon during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image.
• 2-stop band of density across filter that extends approximately 1.6" in both vertical directions before tapering to clear areas that extend 2.6" until they meet the top and bottom edges of the filter.
• Creates a neutral density pattern that matches the positioning of the sun when it is at or immediately above the horizon.
• Density pattern to specifically match the brightness pattern of the sun when it appears at or is close to the horizon as opposed to a higher angle, which creates an increase in brightness that is much more prominent on both sides of the sun than either above or below it.
• Soft-edged line of transition between the 2-stop band of density and the clear areas above and below it are useful for images that have features alongside the sun that cannot be confined within the band of density.

Q: 1. How does this attach to the phone? I have a clip on ND I'm not happy with since it has light leaking in.

A: The Kase ND64 6-Stop ND Filter for Smartphones BH #KA1117130001 would come with a stick on L-Shaped Magnetic Adapter that is semi-permanent adhesive.

Q: 2. Works for sony 24-70 mm?

A: Depends which 24-70 you are referring to. Sony FE 24-70mm f/2.8 GM II Lens accepts 82mm filters so this 67mm filter won't work.

Q: 3. Can all three be stacked to view solar eclipse?

A: No. They may cut down on the visible wavelengths of light, but won't do anything about the infrared light which will still fry your eyeball and camera electronics.

Q: 4. I plan on using this filter with my canon 70-200mm L series lens. Will I still be able to use the lens hood with this filter?

A: K&F Concept 77mm Nano X-Pro Magnetic ND2-32 (1-5 Stop) Variable Neutral Density Filter is very wide in the front and the lens hood in the Canon 70-200 is very narrow so the lens hood will probably not work with the filter unfortunately.

Q: 5. Does this have front threads? So I could mount a lens hood? Or stack a filter?

A: No, the K&F Concept Nano X-Pro HD Variable ND2-400 Filter (62mm) does not have any front threads for mounting a filter or hood.

Q: 6. What are the filter dimensions? 100x100 mm?

A: Cokin*

Q: 7. Does the orange tab is removable? im afraid it is going to bump my matte box

A: The orange tab on the K&F Concept Nano X-Pro HD Variable ND2-400 Filter (82mm) is not made to come off.

Q: 8. will I be able to use the hood on my 35mm 1.2 voightlander with this filter?

A: I have this filter in 49mm on a Pentax FA 43 and I am able to screw on a B+W metal hood with no problem.

Q: 9. Can they be stacked together to increase the final f-stop. i.e. 1 f-stop filter + 3 f-stop = 4 f-stop?

A: Yes they can!

Q: 10. Work for Sony FE 50mm f/1.8 Lens?

A: Yes, the K&F Concept Nano-X Pro Variable ND2-ND400 Filter (49mm, 1-9 Stop) will work on the Sony FE 50mm f/1.8 Lens.
