The 100 x 150mm H&Y K-Series Graduated ND Filter 100x150mm 4-Stopfrom H&Y K-Series Graduated ND Filter 100x150mm 4-Stopis a rectangular filter that helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a hard-edged line of transition between the dense and clear areas. A graduated neutral density filter with a hard-edged line of transition is particularly useful for images that feature horizons, or any hard transition between the sky and land. Neutral density filters do not affect the coloration of the image and this filter provides up to a 4-stop reduction in light from entering the lens.

100 x 150mm K-Series Hard-Edge Graduated Neutral Density Filters are constructed from Gorilla glass for enhanced scratch-resistance, increased clarity, and color fidelity. Each side of this filter includes eight layers of anti-reflection coating to prevent internal ghosting and reflections as well as an anti-smear, nano coating for an improved beading effect when in contact with water or oil for greater cleaning efficiency.

The 100 x 150mm K-Series Hard-Edge Graduated Neutral Density 1.2 Filter is pre-installed with an H&Y K-Series Graduated ND Filter 100x150mm 4-Stopfor use with an H&Y Filters 100mm K-Series Filter Holder. When combined with a 100mm K-Series Filter Holder that is configured with a pair of magnetic filter slots, filters each with a Quick Release Magnetic Filter Frame can be magnetically stacked in front of a camera lens instead of inserted only within a specific number of filter holder slots, allowing the user to determine the number of filters to be applied, all of which can be quickly installed, repositioned, or switched with a different filter needed for other subjects or changing lighting conditions.

While in use, front-facing center finder rulers on the side sections of this Quick Release Magnetic Filter Frame help enable precise positioning of the 100 x 150mm graduated neutral density filter, relative to another filter it is stacked on. This can further complement the use of the 100 x 150mm graduated neutral density filter whose effect can be adjusted to better suit changing lighting conditions or creative demands by moving it up or down. The Quick Release Magnetic Filter Frame also serves to reinforce the edges of the 100 x 150mm graduated neutral density filter, enhancing that filter's rigidity and promoting sharp results by helping to ensure that the filter remains flat. A filter pouch for storage and transport, as well as a microfiber cleaning cloth for filter maintenance, are also provided.

Related Questions and Answers

Q: 1. 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: 2. What is the difference between this item and ICND1000SI082?

A: The ICND100SI082 is made from Tempered Optical Glass for shock resistance. The one here, the ICND100082 does not use Tempered Glass. All Solid Ice Filters use Tempered Glass. The regular Ice Filters do not use Tempered Glass.

Q: 3. Will this fit on the DJI Osmo?

A: Does the lens have a filter size specified on it? I looked at the online photo of this camera, I'm not sure I can see filter threads on the lens. You can measure the diameter of the lens in millimeters, but it has to have filter threads on the lens to accept this type of filter.

Q: 4. Will this 77mm filter fit onto the Canon RF 70-200mm f2.8 lens with the supplied Canon lens hood attached?

A: Yes, the Ice 77mm ND32 solid ND will work with the RF 70-200mm f/2.8 and its hood without issue.

Q: 5. Can a lens hood be used with this filter, specifically for a sony 24-70 2.8 v1?

A: No, the Nano-X Variable ND filter will not work on the Sony 24-70mm f/2.8 GM I with the lens hood on. Both the polarizing and variable ND knobs on the filter prevent the lens hood from mounting on the camera. If you use fixed ND filters, you can use the lens hood.

Q: 6. is it work with "NiSi V6 100mm Filter Holder"?

A: Yes, these filters will work in the Nisi holder.

Q: 7. Can I screw this along with a 77mm circular polarizer?

A: It depends on your polarizer. Some thin profile polarizers don't include threads to put more filters. In any case, this filter is already super dark, add a polarizer and it would be incredibly dark. The quality might also suffer, and with this filter it's not very good to begin with.

Q: 8. 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: 9. Will this fit well with the format hitech 85mm holder? It should fit similar to cokin P but want to make sure its not a tad smaller and cause leakage.

A: I measured my ND filter with a vernier digital caliper. My measured dimensions are 83.9 to 84.5 mm x 99.9 to 100.1 mm. This is the only information I can provide because I have not yet shot photos with this ND filter.
