This 4 x 4" Tiffen 4x4" ND Filter 1.3-Stopis a solid neutral density filter providing a 1.3-stop exposure reduction. This 0.4 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: 4. Hi thereI'd like to know if there is any difference between this ND filter and the one (please see the link).Thankshttp://www.bhphotovideo.com/c/product/86020-REG/Tiffen_45650ND9_4_x_5_65_Neutral.html

A: The difference between the two filters is that theTIND.9W45P filter (the more expensive of the two) is made with Tiffens Water White Glass. This will make the filter less likely to give a color cast to the image.

Q: 5. Looking to put this on my voigtlander 17.5mm so I can shoot video at f/2.0 in daylight. With a 3stop ND filter I own, I have to shoot at f/8 to shoot at 1/50 shutter for video. If my math is correct, I would need at least 7 stop filter for f/2.0. When does the infamous cross pattern show up on this filter?

A: Thanks for your interest in the Tiffen VND filter. The X Bar is dependent upon three factors.... the sensor size of your camera, your focal length and your VND setting. There is no way to say when exactly it will happen. The X Bar typically happens when shooting wide angle and when using higher density settings on the VND. This will happen sooner with a full frame sensor. To eliminate the X Bar you would simply adjust your focal length (zoom in), go to a lighter density setting on the VND or a combination of both.The X Bar effect is a product of optical physics and does not indicate that anything is wrong with the VND filter. If it appears you are simply operating outside of the recommended VND parameters.

Q: 8. Is this an IR cut ND filter as well?

A: This is not an IR filter

Q: 9. Do the marks correspond to fixed stop values to allow calculating exposure settings?

A: The "Marks" correspond to approx 1/2 stops.

Q: 10. Does anyone know if my Nikon 24-70mm f2.8 VR lens hood works with this filter attached?

A: I assume you mean the 77mm version of the variable ND... because this is the 82 mm which of course will not fit ... guess you can use a stepup ring? But it will work for sure if it fits you lens... pretty sure there is a 77mm version. The variable ND is ideal for shooting video where you are maintaining a shutter speed and F stop or T stop with a specific depth of field and you need to drop the amount of light coming in plus you cannot drop the ISO any further. That's what I use it for anyways.
