The 130 x 170mm Cokin NUANCES X-Pro Reverse-Graduated ND Filter 130x170mmis designed for use with a Cokin X-Pro Series Filter Holder. It can be applied to darken bright skies, specifically 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 a 2-stop reduction in light from entering a lens. This band extends in both vertical directions which tapers to a 0.3 density that provides a 1-stop reduction in light at the edge above it. Directly below the 0.6 band of density, it tapers to clear, with a soft-edged line of transition before the clear area.

The placement of a 0.6 band of density that tapers to a density of 0.3 above it with a clear area directly below, allows the Cokin NUANCES Extreme X-Pro Series Soft-Edge Reverse-Graduated Neutral Density 0.6 to 0.3 Filter to match the positioning of the sun when it is at, or immediately above the horizon. In such instances, the sun can appear closer to the center of an image as opposed to the upper edge, and an increase in brightness is created that is more prominent on both sides of the sun than above it. This pattern of brightness corresponds to the density pattern on the Cokin NUANCES Extreme X-Pro Series Soft-Edge Reverse-Graduated Neutral Density 0.6 to 0.3 Filter. The soft-edged line of transition in this reverse, graduated neutral density filter is useful for soft transitions between the sky and land, while the 2-stop to 1-stop gradation is applicable to multiple regions of brightness within the sky.

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 bright skies, specifically during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image.
• 2-stop band of density that tapers to a 1-stop density at the edge above it while directly above a clear area creates a neutral density pattern that matches the positioning of the sun when it is at, or immediately above the horizon.
• 2-stop band of density extends in both vertical directions.
• Density pattern corresponds to the brightness pattern of the sun when it appears at or is closer to the horizon as opposed to a higher angle, which creates an increase in brightness that is more prominent on both sides of the sun than above it.
• Soft-edged line of transition between the 2-stop band of density and the clear area below it is useful for images where the transition between sky and foreground is indeterminate, such as images featuring mist, fog, or the tops of trees.
• 2-stop to 1-stop gradation is applicable to multiple regions of brightness within the sky.
• Filter does not affect the overall coloration of the image.
• Tempered, shock-resistant glass construction maintains high optical clarity with low reflectivity.
• A nano-metallic alloy applied to both sides of the filter attenuates infrared light and ensures neutral coloration even when stacked with other Cokin NUANCES or NUANCES Extreme filters.
• Anti-glare coatings help to reduce surface reflections for increased contrast and color fidelity.
• Hydrophobic coatings result in an improved beading effect when in contact with water for greater cleaning efficiency.
• C-shaped edges resist chipping to further enhance durability.
• Padded filter pouch is included for storage and transport.

Q: 1. Do the filters come in their own hard plastic protective box?

A: Yes, they are individual.

Q: 2. What are the filter dimensions? 100x100 mm?

A: Cokin*

Q: 3. how does this attach to the lens? will it work with a lens with a 95mm filter ring?

A: The following 95mm adapter rings can fit the Cokin Z holder: https://bhpho.to/31LpXxd

Q: 4. Please what is the outer (unthreaded)diameter of this adapter?To work strait on my Chromatek compendium it should be 10.8mm.Can't find the original adapters anywhare..Thank YOu so much for telling me :-)

A: The Cokin 82mm Z-Pro Adapter Ring is 4 in diameter.

Q: 5. What is the outside diameter of this ring ?

A: The Cokin Z-Pro Series Filter Holder Adapter Ring (67mm) has an outer dimater of roughly 100mm. This is meant to perfectly fit the Cokin Z-Pro Series Filter Holder.

Q: 6. Will this mate with a Lee 100 filter holder?

A: No, Cokin Z-Pro Series Filter Holder Adapter Ring can not be attach to LEE Filters LEE100 Filter Holder. Cokin adapter rings slide on the holder while Lee rings are design with a bayonet to clamp on their holder. Both system are proprietaries.

Q: 7. what is the outside diameter of this ring?? cant find this anywhere on the web haha

A: Its basically 77mm plus the thickness of the very thin metal. So maybe 79mm total. But all that should concern you is that a 77mm diameter filter will fit in it.

Q: 8. 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: 9. Can these filters be trimmed down, cut with a razor?

A: The Cokin P Series ND 0.3 Filter (1-Stop) is a hard plastic and is not really designed to be cut / trimmed. These two can be cut with a scissor, https://bhpho.to/407PRER .

Q: 10. Can I use this adapter on a brass 55-67 step up ring as have two different lenses?

A: Yes, you can you a step-up ring adapter, 55-67. So, you can use the same Cokin ring for lenses that use a 55mm filter thread.
