Exhibiting improved clarity, flatness, and reduced reflectivity, the 100 x 150mm Firecrest Ultra Soft Edge Graduated ND Filter from Formatt-Hitech helps 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 0.3 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 0.3 filter for darkening skies and other bright areas of the image.

Provides a 1-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. I assume to use this you have to rotate the whole mounting assembly. Yes? How easy is this to do? Does this scratch up the lens housing?

A: This filter is rotated in the holder and is smooth functioning and does not scratch the housing.

Q: 2. Would this fit a Lee holder? How is the colour neutrality vs Lee big stopper and little stopper (who high on think have too strong a colour caste)?

A: The, B+W 100 x 100mm XS-Pro MRC-Nano 815 ND 4.5 Filter (15-Stop) is one of the better ND filters. And is very good for low color cast. And yes, it will fit into the Lee 100mm holders. Like lee filters the filter is 2mm thick.

Q: 3. This is because I use it with the H & Y magnetic frame so that my filter cannot be sticked with sponge (for prevent light leakage). Do you know that this filter has sticked sponge?

A: I'm sorry but this filter does not have foam on the edges.

Q: 4. does this work on this system http://nikonrumors.com/2013/09/07/fotodiox-wonderpana-145-adapter-kit-for-the-nikon-14-24mm-f2-8-lens-review.aspx/and has anyone used it and liked the results??? susan

A: Yes, the FotodioX 145mm Pro Ultra Slim Neutral Density Filter is compatible with the Wonderpana 145 Adapter Kit for the Nikon 14-24mm f/2.8. Unfortunately, no one has reviewed this combination on our website.

Q: 5. What filter system do you recommend/use with this filter?

A: This is a 100 x 100mm - 2mm thick filter, and one of the most popular systems for that size is the LEE Filters LEE100 Filter Holder (https://bhpho.to/2Tg0TrU)

Q: 6. is this filter compatible with nisi v5 100mm system?

A: Yes the B+W 100 x 100mm XS-Pro MRC-Nano 803 Solid Neutral Density 0.9 Filter is compatible with the NiSi V5 Pro 100mm Filter Holder Kit at 100mm x 100mm, and 2mm thick.

Q: 7. Can additional filters be added on top of the Nano 810 to stack filters?

A: There is a 67mm front thread on this filter, so you can stack filters as needed. However, there is a risk of vignetting as you add more than one filter.

Q: 8. Can other filters screw on to the Nano filter to stack filters?

A: Unfortunately this filter is too thin to stack any more filters on top of it.

Q: 9. Is this filter compatible with Lee Filters Foundation Kit (Standard 4x4") B&H # LEFK ?

A: Yes, this filter will fit with the Lee Filter Foundation Kit.

Q: 10. Does it fits 4"x4" Tilta Mattebox?

A: No, the Haida 100 x 100mm Circular Polarizer Filter will not fit the Tilta Tiltaing Mini Matte Box 4"x4", the Haida 4 x 5.65" V-Pro Series C-POL Polarizing Filter (BH #HAVPCP45) will.
