The Tokina 6.6x6.6 PRO IRND 0.3 Filter 1-Stopis compatible with filter holders that can accommodate filters that are 6.6" wide and 4mm thick. It is an ND filter with a 2x filter factor that provides a 1-stop exposure reduction. This filter's 0.3 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower 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. Neutral density filters are intended to not affect the coloration of the image and are ideal for pairing with other filters.

The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible 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. To provide a high level of neutrality across the visible and infrared spectrums in order to eliminate color casts and ensure cleaner, truer blacks when using this filter, one ACCU-ND Vapor Deposition layer is sandwiched between two layers of optical glass.

This Tokina 6.6 x 6.6" PRO IRND 0.3 Filter is constructed from optical glass for clarity as well as color fidelity, and its sandwich design protects the ACCU-ND substrate while the glass surfaces can be re-polished should they become accidentally scratched.

Related Questions and Answers

Q: 1. What's the weight of the filter Could it be used instead of the balancing ring needed for the X5S?(drone proposes).

A: The weight is not provided by the manufacturer and we do not have a way to weigh it. It would be best to contact the manufacturer to find out if they know that information; B+W/Schneider Optics can be reached at 800-645-7239.

Q: 2. What is the weight in grams of just the filer itself (no lens cap)?

A: The K&F Concept Nano X-Pro HD Variable ND2-400 Filter (82mm) weighs about 1.6 ounces which is about 45 grams.

Q: 3. will it work with the nisi v6 holder?

A: The K&F Concept X-Pro Square ND64 Filter with Frame (100x100) is not compatible with the NiSi V6 Filter Holder. This item is designed for use with the X-Pro Square Filter Holder System.

Q: 4. Can screw on filters be stacked on top of the Nano 810 filter?

A: No you can not stack filters on top of this one. I would suggest that this be the last filter of the stack.

Q: 5. How many stops is 1.5?

A: In ND measurements 1.5 is 5 stops of ND

Q: 6. Works for sony 24-70 mm?

A: Depends which 24-70 you are referring to. Sony FE 24-70mm f/2.8 GM II Lens accepts 82mm filters so this 67mm filter won't work.

Q: 7. Can I mount this filter on my zeiss planar f 1.4 50 mm ?

A: If you own the Zeiss Planar T* 50mm F/1.4 ZF.2 Lens, B&H # ZE5014ZF2N, which has 58mm filter threads, yes, the B+W 58mm XS-Pro Digital ND Vario MRC nano Filter would be compatible for use with your lens.

Q: 8. Would combining one of these with the Tilta Mirage's VND filter cause issues? I realize these are IRND and the VND is not, but I'm thinking I may sometimes need more than the 2.7 stops the VND offers.

A: Using the Vaxis VFX 95 IRND 1.5 Filter for Tilta Mirage Matte Box with another ND filter will increase internal reflections from the layers of glass, but it can be done.

Q: 9. Does this have a hard stop on it or does it rotate a full 360+?

A: The stops are indicated on the filter, however there is no pushback or hard stop as you rotate the ring.

Q: 10. I purchased this filter from you earlier this month. The filter ring is oversized . Can you recommend a lens cap that would work with this filter? Thank you. - Michael

A: The front filter thread size of the B+W 72mm XS-Pro Digital ND Vario MRC nano Filter is 77mm. As such, any 77mm lens cap should fit onto the filter. If you need a particular recommendation, then I would recommend the Sensei 77mm Center Pinch Snap-On Lens Cap, B&H # SELC77, for your stated needs.
