Exhibiting improved clarity, flatness, and reduced reflectivity, the 100 x 150mm Formatt Hitech Firecrest Ultra Soft Edge ND Filter 100x150mm 3-Stopfrom Formatt Hitech Firecrest Ultra Soft Edge ND Filter 100x150mm 3-Stophelps to balance the overall exposure within a high-contrast scene. Ideal for situations involving both bright and dark areas, such as an open sky and shadowed foreground, half of the filter has 0.9 neutral density and the other half is clear, with a soft-edged transition between the two that is ideally suited for use with medium and wide-angle lenses or when there is an uneven, undulating horizon. By reducing the exposure in selective areas, you are able to balance the overall exposure of the scene in order to gain detail in both bright and dark areas.

Designed using inspiration from their cine Firecrest filters, these Ultra filters receive an additional lapping and polishing process during production to ensure lower reflectivity and improved clarity and sharpness. This filter has also been optimized for use with digital sensors and promotes nearly flat attenuation of visible, UV, and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times. This filter provides a high level of neutrality across all three spectrums in order to eliminate color casts and ensure cleaner, truer blacks.

Applied to the outside of the Schott Superwite glass construction is a 15-layer Firecrest multi-coating, which helps to minimize reflections and flare in order to maintain truer colors and contrast. The multicoating is also scratch resistant and hydrophobic to benefit the overall durability of the filter. It measures 100 x 150mm and is 2mm thick, making it compatible with the Formatt-Hitech 100mm Filter Holder.

The Ultra Firecrest series filters exhibit greater clarity and have lower reflectivity than the original Firecrest filters. Borrowing from the range of Firecrest cine filters, the Ultra series filters undergo a secondary lapping and polishing process after the initial polishing and bonding stage. This additional step helps to ensure flatness and consistency for improved image quality.

Graduated ND 0.9 filter for darkening skies and other bright areas of the image.

Provides a 3-stop reduction in light in selective areas.

Soft-edge transition is ideal for circumstances there is not a distinct line of separation between the bright and dark zones of the image.

Vertical orientation filter's line of transition runs parallel to the short side of the filter.

Attenuates infrared light, as well as visible and UV wavelengths, to maintain color neutrality and suppress color casts due to increased exposure lengths.

The 15-layer Firecrest coating has been applied directly to the outside of the filter glass by way of a vacuum-formed, hard-coated, electrolytic process. The multicoating is water and scratch resistant for greater overall durability.

Schott Superwite glass promotes maintained image clarity and its 2mm-thick design is compatible with the Formatt-Hitech 100mm Filter Holder.

Q: 1. What is the thread pitch for this product 60 X .75? Are these external threads? Thanks

A: The B+W 60mm 0.6 ND MRC 102M Filter has a 0.75mm pitch which is standard for many filters.

Q: 2. What diameter lens cover will fit over this filter please?

A: The lens cover for your lens should fit over the filter. So if your lens is 95mm, and your filter is 95mm, then you need a 95mm lens cover.

Q: 3. Is it really made in Japan like the picture shows?

A: Yes, this filter is made in Japan.

Q: 4. I have a vivitar 0.43x wide angle filter that accepts 62mm filter threads. I'm considering getting this Bower 62mm Variable ND filter and a 58-62 step up ring so I can use it on both the wide angle filter and my Canon G40's lens. My question is; would there be any amount of vignetting that would render the use of the ND filter on the wide angle filter pointless? How much of a vignette should I expect?

A: I can confirm what Roland said, this filter becomes unusable at its maximum/darkest setting. Roll it back just a bit and it's fine, but do keep that in mind.

Q: 5. What's the weight of the filter Could it be used instead of the balancing ring needed for the X5S?(drone proposes).

A: Unfortunately we cannot weight any products here and the manufacturers do not provide the weight of lens filters. It may be best to ask your question on the drone Q&A itself, but we would guess that it is the same weight and could be used as a balancing ring if necessary--though it is not an exact measurement.

Q: 6. Any vignette on a lens with 77mm thread? How is edge distortion?

A: These is no vignetting unless the lens is wider than 28mm. These is no noticeable edge distortion either.

Q: 7. Will this fit my Leica Q? I saw someone say that it wouldnt fit the leica 28mm lens.

A: Yes, the Leica Q takes a 49mm filter, so this will fit.

Q: 8. What lens caps fit?

A: this should work , ZEISS 86mm Front Lens Cap B&H # ZEFLC86

Q: 9. Will this vignette with 7.5mm ultrawide Laowa lens?

A: You will get some vignetting when using this filter on the 7.5 but can be corrected in post.

Q: 10. 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.
