Exhibiting improved clarity, flatness, and reduced reflectivity, this 46mm Hitech Firecrest Ultra ND Filter 46mm 2-Stopfrom Hitech Firecrest Ultra ND Filter 46mm 2-Stopis a neutral density filter providing a 2-stop reduction in exposure. This 0.6 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or longer shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. 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.

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 multicoating, 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. The filter is set within a 5.5mm-thick SuperSlim aluminum filter ring, which features front threads for stacking additional filters or attaching a lens cap.

This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.

The Firecrest Ultra 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.

ND 0.6 filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

Providing a 2-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.

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 resistance for greater overall durability.

Q: 1. https://www.bhphotovideo.com/c/product/1081648-REG/zeiss_2059_812_front_lens_cap_86mm.html (Can this lens cap be used?)

A: B+W 82mm XS-Pro Digital ND Vario MRC-Nano has an 86mm front threaded diameter. ZEISS 86mm Front Lens Cap would be perfect for your filter.

Q: 2. Does this vignette on the tokina 11-20mm 2.8?

A: No there will be no vignetting when using the B+W 82mm XS-Pro Digital ND Vario MRC-Nano Filter. XS-PRO filters are designed with a thinner ring so they can avoid vignetting on a wide angle lens.

Q: 3. Will this filter fit a canon zoom EFS 55-250mm (58mm)?

A: The Tiffen Solar ND Filter (55mm, 18-Stop, Special 50th Anniversary Edition) is too small for the Canon EF-S 55-250mm f/4-5.6 IS STM Lens. Instead, get the Tiffen Solar ND Filter (67mm, 18-Stop, Special 50th Anniversary Edition), BH #TI67ND54, and the Sensei 58-67mm Aluminum Step-Up Ring, BH #SESUR5867.

Q: 4. Does this filter vignette with a Panasonic 8-18 lens at 8mm with gh5s?

A: This is a 72mm filter, the Panasonic Leica DG Vario-Elmarit 8-18mm f/2.8-4 ASPH. Lens has a 67mm filter thread. Instead you would need BH #BWNDVXSP67 for that lens. https://bhpho.to/2YH9VNd

Q: 5. Will this filter fit the Nikon AF-S 200-500mm 1:5.6E ED lens?

A: Yes the Tiffen Solar ND Filter (95mm, 18-Stop, Special 50th Anniversary Edition)with fit the Nikon 200-500mm lens.

Q: 6. How can we clean the inside of the filter?

A: I must admit in a career of photography never needing to clean the inside of a rotating Polarizer. If for some really reason you actually had to clean the inside, that would be a task for a professional camera technician. No user serviceable parts are here.

Q: 7. Hi. Can this filter be used on a Leica 50mm APO-Summicron-M ASPH f/2.0 lens? Thank you.

A: The lens has a 39mm filter thread. This filter would not be compatible. B+W makes the same filter in 52mm. If you use a 39-52mm step up ring, then you will be able to use this filter on the Leica lens.Here is the step up ring: http://bhpho.to/1u0UKvfHere is the filter: http://bhpho.to/1qoJGa9

Q: 8. Will this filter fit the Sigma 16mm f/1.4 lens?

A: Yes, it fits.

Q: 9. with an ultra-wide angle lens (i.e. Canon 16-35mm F4L with a full frame camera), do you get the dreaded X show up and if so at what density does it show up?

A: The X you can sometimes pick up in the image with a variable ND filter is caused most of the time by variable ND filters that go over 7-8 stops and lower quality ones.The B+W filter is fine. The one thing you might pick up is when set to the widest setting on that lens, 16mm you might pick up some vignette. And that is going to happen with that lens with most filters because of how wide it can go. The filter is designed with a thinner frame so it should be somewhat minimal.

Q: 10. Does B+W 82mm XS-Pro Digital ND Vario MRC-Nano Filter cause any vignetting and X-shadow at 15 mm end (Canon 15-35 mm RF 2.8 lens)? Thanks

A: There is a possibility of slight vignetting at 15mm.
