The 4 x 5.65", 3- to 2-stop Cokin Z-Pro Reverse-Graduated ND Filter 4x5.65" 3-2 Stopis designed for use with a Cokin Z-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 0.9 band of density across its center region that provides a 3-stop reduction in light from entering a lens. This band extends in both vertical directions which tapers to a 0.6 density that provides a 2-stop reduction in light at the edge above it. Directly below the 0.9 band of density, it tapers to clear, with a soft-edged line of transition before the clear area.

The placement of a 0.9 band of density that tapers to a density of 0.6 above it with a clear area directly below, allows the Cokin NUANCES Extreme Z-Pro Series Soft-Edge Reverse-Graduated Neutral Density 0.9 to 0.6 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 Z-Pro Series Soft-Edge Reverse-Graduated Neutral Density 0.9 to 0.6 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 3-stop to 2-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 Z-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.
• 3-stop band of density that tapers to a 2-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.
• 3-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 3-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.
• 3-stop to 2-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.

Related Questions and Answers

Q: 1. Does this have a hard stop on it or does it rotate a full 360+?

A: The stops are indicated on the filter, however there is no pushback or hard stop as you rotate the ring.

Q: 2. Want to use on a canon ef 100-400 mm to photograph an eclipse. Will it fit/work?

A: Yes,your ND filter will work with solar eclipse. But, that is the least of your problems. If will give the impression that it reduces the light from the sun. It does for visible light, but does NOT reduce the permanent eye damage from UV, which will past through your ND filter as if you had no ND filter. If you do use it for solar eclipse, you MUST, to keep your vision, add add a CERTIFIED solar eclipse filter to stop the very damaging UV light. Without the solar filter, you'll most likely burn out your camera's sensor, along with your vision. Permanently. Wishing you great luck with your solar photos. Respectfully submitted, Bill Edmundson

Q: 3. Will this filter work on a wide angle lens such that there is no vignetting or blocked portions on the image?

A: We use the 52mm as a drop-in for a 200-400 f4 Nikon lens. No problem there.

Q: 4. 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: 5. HelloWould this Filter and the Hoya 52mm Alpha Circular Polarizer Filter work (Compatible) with Panasonic Lumix FZ200?Thank you.Shaun

A: The sizes of both filters are the proper size for the FZ200 and will properly fit it, however Panasonic's instruction for the manual discourages use of two filters on the camera, likely as it will become too darkened for the camera to autofocus with.

Q: 6. Am I right to assume that a 58mm lens cap would fit over this filter?

A: Yes, technically a 58mm lens cap should fit. But filters like these can be wider. They essentially are made up of two polarizing filters sandwiched together. So they can be a bit wider because of that.

Q: 7. Do the filters come in their own hard plastic protective box?

A: Yes, they are individual.

Q: 8. 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: 9. I have a Nikon 50mm f/1.4 lens with a good. The lens cap fits inside the lens and it says 58mm. Will this lens filter fit this lens?

A: Yes, any 58mm filter will fit.

Q: 10. 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.
