Helping to selectively reduce exposure in certain areas, while allowing for a normal, unaffected exposure in other regions, the 82 Formatt-Hitech Firecrest Graduated ND Filter is ideally suited to controlling bright skies without underexposing the foreground. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the density and clear areas. The filter is mounted within a rotating frame, and allows for greater control over the orientation of the density to match certain subject types. Neutral density filters do not affect the coloration of the image and the 0.9 density provides a 3 stop reduction in light from entering the lens.

The design of this filter has been optimized for use with digital sensors and promote 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 maintain truer colors and contrast. The multi-coating is also scratch-resistant and hydrophobic to benefit the overall durability of the filter. The filter is set within a 7.5mm-thick SuperSlim aluminum filter ring, which features front threads for stacking additional filters or attaching a lens cap.

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.

Rotating mount enables control over the orientation of the density for matching to specific subject shapes and compositions.

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 multi-coating is water- and scratch-resistance for greater overall durability.

Schott Superwite glass promotes maintained image clarity and is set within a 7.5mm-thick SuperSlim aluminum filter ring.

Q: 1. Does it fit for Cokin Type Z filter holder? (I purchased Cokin Type Z expert kit last year).

A: This circular polarizer will only work in a 100mm filter holder which accept filters that are 2mm, particularly the Formatt-Hitech Firecrest 100mm holder. The Cokin Z holder only accept filters that are 1.6mm thick.

Q: 2. will these filters fit a Sinar filter holder? would be using on a large format camera with a Nikor 90mm and and Nikor 210mm lens.

A: If you have a Sinar 100 x 100mm filter holder, these filters can fit.

Q: 3. I'm confused. The pictures and specifications indicate these are 100mm X 150mm filters. The answer for, "What comes in the box by 'Manzell L. (Staff) states they are 100mm square. Are they 3 square or rectangular filters?

A: The filters are rectangular. This is common with most graduated neutral density filters since you sometimes need to raise or lower the line where the density changes.

Q: 4. Can I use this filter with the Lee polarizer filter holder?

A: It should fit as long as the polarizer filter holder is 105mm in diameter.

Q: 5. Will this filter fit a 39mm drop in filter for a Nikon F4 600 mm lens?

A: No, that filter will not fit in Nikons two versions of the 600mm lens.The two 600mm lenses are the, Nikon AF-S NIKKOR 600mm f/4E FL ED VR Lens B&H # NI6004EEDVR MFR # 20054AndNikon AF-S NIKKOR 600mm f/4G ED VR Lens B&H # NI6004GEDVR MFR # 2173The f/4E uses a 40.5mm drop in and the f/4G uses a 52mm drop in filter.The recommend polarizing filters are below.

Q: 6. I just watched a video on YouTube where the gent says there are NO filter threads inside but the specs here list that there are?

A: I contacted Formatt-Hitech with your inquiry. They state that the Formatt Hitech 77mm Firecrest SuperSlim Circular Polarizer Filter, B&H # FOFCSSCP77, has 77mm front filter threads. They state you may stack multiple threaded filters onto each other as long as they all have the same 77mm filter thread diameter size.

Q: 7. There will be vignetting when used with Zeiss Distagon 15mm?

A: This filter will not vignette nor will that lens.

Q: 8. I'm wondering what the "stop" range on this filter is?

A: The Formatt Hitech 62mm Firecrest SuperSlim Circular Polarizer Filter, B&H # FOFCSSCP62, has a filter factor of 2.5, which would reduce 1.3 stops from your normal exposure.

Q: 9. Will these filters fit the Lee 100 system holder?

A: Yes, these filters will fit the Lee Foundation Kit.

Q: 10. How about the thickness of the filter???

A: There is no information about the precise thickness of the filter, but it is much thinner than a standard circular polarizing filter.
