The Tokina 6.6" PRO IRND 0.6 Filter 2-Stopis compatible with filter holders that can accommodate filters that are 6.6" wide and 4mm thick. It is an ND filter with a 4x filter factor that provides a 2-stop exposure reduction. This filter's 0.6 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 0.6 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.

Q: 1. Can this fit on Fuji 50mm F1.0 lens?

A: Yes, they are both 77mm threads.

Q: 2. Can these be used with step-up rings without optical problems?

A: Yes, step up rings will not be a problem with this filter.

Q: 3. 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: 4. Does this Variable ND Filter suffer from color cast? How much color correction is needed in post if any? Compared to no ND filter what is the color temperature? Thanks

A: These Polarpro filters are very good and have little or no color cast to speak of.

Q: 5. why isn't there a 72mm?

A: This filter is not available at 72mm at this time. However we do have other higher quality options that are, such as the B+W 72mm XS-Pro Digital ND Vario MRC-Nano Filter, BH #BWNDVXSP72. https://bhpho.to/2V2u8vJ

Q: 6. How many stops is 1.5?

A: In ND measurements 1.5 is 5 stops of ND

Q: 7. Is this newest version? Version 2?

A: No this is the mark I.

Q: 8. Does this have IR filtration built in? Because I plan on using it with a BMPCC 6K and don't want IR pollution changing the colors as I step down.

A: The PolarPro 82mm Peter McKinnon Edition Variable Neutral Density filter is made of Quartz Glass. Quartz Glass has excetionally high tramissision of the entire visible spectrum inclding UV and IR. If you need UV filtration use a seperate UV filter.

Q: 9. Does this have 82mm threads on the front to attach a lens hood?

A: This filter does not have front threads.

Q: 10. Hi, interested if if this is the first or second edition from PolarPro for the variable ND filter. Thank you

A: This is version one.
