This 4 x 4" Tiffen ND Filter is a solid neutral density filter providing a 3.3-stop exposure reduction. This 1.0 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 4" / 101.6 x 101.6mm.

Q: 1. Is the end of this filter threaded?

A: The side of this ND filter that faces outward, away from the camera lens to which it is attached, is NOT threaded.

Q: 2. I purchased a 77mm Tiffen Variable ND Filter from you recently--can I get an adapter to adapt this to my Olympus 40-150mm Pro f2.8 lens? Also, is there any problem adapting ND Filters?

A: Without checking, I'm pretty sure you can get an adapter here from B&H. There should be no problem since your 77mm is larger than the 72 mm size of the Olympus lens B&H Shows it to be. Sometimes there is a problem with the filter causing light drop off around the edges but I would think you should be OK with a normal adapter, but you could also see if they have a thin adapter specially designed to minimize that problem in wide angle lenses where it is more prevalent (those in the 24-70 range), etc., but at 40 mm, I'm thinking you wouldn't have a problem either way!

Q: 3. Hello, I am new and wondering, does anyone know if this will fit this lens? https://www.bhphotovideo.com/c/product/1369132-REG/sigma_402965_16mm_f_1_4_dc_dn.html

A: Yes it will.

Q: 4. Can this be used with the Tamron 50-400 with hood attached?

A: No, you cannot use the Tiffen 67mm Variable Neutral Density Filter with the Tamron 50-400mm f/4.5-6.3 Di III VC VXD Lens for Sony E while the lens hood is attached.

Q: 5. What's the pitch of the threads?

A: Not sure about "thread pitch" however, I can say that is threads on & off my Canon RF 24-70mm f/2.8L IS USM Lens just fine.

Q: 6. since this filter use two polarizing filters to achieve blocking of the light, will this cause uneven distribution of the light, depending on the shooting angle?

A: As long as you are within the lens specifications you will not experience any uneven light distribution. I have never had a problem unless using at the dense or dark end of the limit and with a wide focal length on zoom or a wide angle lens

Q: 7. Does this filter work with Canon RF 15-35mm Lens?

A: Yes.

Q: 8. Wil; this filter work with a Nikon 18-300mm f/3.5-6.3 zoom lens ? Also, will I get the notorious X-pattern at 18mm?

A: The Tiffen 67mm Variable Neutral Density Filter is compatible with the Nikon 18-300mm f3.5-6.3 lens. The "X" pattern only occurs when the filter is rotated beyond the 8 stop range (beyond the limit for the filter).

Q: 9. Can I use this filter with step down rings for my other smaller 52mm, 58mm, 72mm lenses?

A: Tiffen's 77mm Variable ND filter can used on your smaller diameter lenses provided you have the appropriate stepping rings (ie - 52mm to 77mm, 58mm to 77mm, etc.)

Q: 10. Will this work on a canon xf100? And will this variable ND blur out the background of shots if necessary?

A: Yes, the XF100 has a 58mm thread. The nd filter cuts down on light thereby opening up the aperture to let more light in and giving less depth of field and blurring the background, and will only do that if you can adjust the aperture of your lens.
