This 3-stop, 150 x 170mm Kase Wolverine Reverse-Graduated ND Filter 3-Stopis compatible with a Kase 150 x 170mm Filter Holder or other filter holders that can accommodate 150mm-wide, 2mm-thick filters. 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 above its center region that provides up to a 3-stop reduction in light from entering a lens. This band extends in both vertical directions and tapers to approximately a 0.3 density and a 1-stop reduction in light at the edge above it. Directly below the 0.9 band of density, it tapers to clear, with a hard-edged line of transition before the clear area.

The placement of a 0.9 band of density with a clear area directly below allows the 150 x 170mm Wolverine Reverse-Graduated ND 0.9 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 150 x 170mm Wolverine Reverse-Graduated ND 0.9 Filter. The hard-edged line of transition in this reverse-graduated neutral density filter is useful for hard transitions between the sky and land, while the 3-stop to approximately 1-stop gradation is applicable to multiple regions of brightness within the sky.

Kase Wolverine filters are constructed from tempered, optical glass for shock resistance. To prevent internal ghosting and reflections, while further enhancing clarity and color fidelity, each glass surface includes multiple layers of anti-reflection coatings. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.

A padded pouch is included for storage and transport.

Related Questions and Answers

Q: 1. Will this work with the normal magnetic filter rings you get in wolverine kits if the mm size is the same?

A: Yes, the Kase Wolverine Magnetic ND64,000 Solid Neutral Density 4.8 Filter with 82mm Lens Adapter Ring (16-Stop) is part of the Kase Wolverine Magnetic system and will work with other Kase Wolverine Magnetic filters.

Q: 2. This filter works with canon 70-200 L 2.8 lens?

A: Yes, the Kase Wolverine Magnetic Solid ND Filter with Lens Adapter Ring will work on the Canon 70-200mm L f/2.8 lens. Please note that the Canon RF 70-200mm f/2.8 L IS USM Z Lens uses an 82mm filter thread—make sure you order the correct filter thread size for you lens.

Q: 3. Does this filter have UV and IR protection coatings?

A: No, the Kase Wolverine ND100000 Magnetic Filter with Adapter Ring (95mm, 16.5 Stop) does not have UV and IR coatings.

Q: 4. Is it possible to remove and mount lens hood while the magnetic adapter is attached to the lens thread ?

A: It will depend on the particular hood that is used with magnetic adapter that is included with the Kase Wolverine Magnetic ND32,000 Solid Neutral Density 4.5 Filter with 82mm Lens Adapter Ring (15-Stop). If the hood is very narrow, the magnetic adapter may get in the way and not allow you to mount it, but wider hoods that flare out, usually will work fine with the magnetic adapter on the lens.

Q: 5. Hola, I my lens is 82 mm 16mm wider what filter do I need?

A: The manufacturer suggests using the Kase Wolverine Magnetic ND64 Solid Neutral Density 1.8 Filter with 95mm Lens Adapter Ring (6-Stop), BH # KAND64MR95 https://bhpho.to/3xqK9jJ

Q: 6. what's the difference between the Skyeye and Wolverine series from Kase?

A: The difference between the Skyeye filters and the Wolverine Magnetic Circular filters are the Skyeye filters have a filter thread on the outside frame, making them compatible with standard screw in filters. The Skyeye also gives you some of the same benefits as the Wolverine filters when it comes to color balance and clarity. The difference lies in the additional coating on the Wolverine Magnetic Circular filters and no filter thread on the outside frame, making them slimmer and lighter. The Wolverine filters have an additional nano coating which makes the filters scratch resistant, waterproof, anti reflective, easy to clean and toughened glass.

Q: 7. Does this need to be combined with a uv/ir cut filter to do solar photography?

A: No, the Kase Wolverine Revolution 100000ND Filter with Magnetic Adapter Ring does not need to be combined with another filter to do solar photography. However, it is important to note that this product can still cause severe damage if used for directly viewing the sun, whether or not through an optic, or a camera with an optical viewfinder.

Q: 8. What is a good lens ca that works with the magnetic mount?

A: Ideally, a good lens cap for the Kase Wolverine Magnetic Variable Neutral Density Filter with Adapter Ring, Gen 2 (58mm, 1.5 to 5-Stops) would be a "snap-on" cap, like the Sensei 58mm Center Pinch Snap-On Lens Cap (B&H # SELC58). The cap clips to the rim of the filter, similarly to how it would snap on the lens. The Kase 58mm Magnetic Lens Cap (B&H # KAKWMC58) would work as well. Here are some of the suggested lens caps for the Kase 58mm filter: https://bhpho.to/3rydji8

Q: 9. Kase USA website does not even mention solar, just 16.5 ND Is this filter really safe for mirrorless sensor and eye with EVF?

A: The Kase Wolverine Revolution 10000ND Filter with Magnetic Adapter Ring (95mm, 16.5-Stop, Orange) does not cut UV and IR light. UV light could damage your eyes. The MrStarGuy 95mm Thread-in White-Light Solar Filter, BH #STSG95MMSOL, cuts UV, IR, and white light. The material looks wrinkled, and it is designed that way. This will not affect the image quality.

Q: 10. Do you recommend using this filter for the solar eclipse next year?

A: The Kase Wolverine Revolution 10000ND Filter with Magnetic Adapter Ring (112mm, 16.5-Stop, Orange) would be a great option for solar photography. It is not rated as safe for solar viewing.
