The Tokina PRO IRND 1.5 Filter 5-Stop 6.6x6.6"is compatible with filter holders that can accommodate filters that are 6.6" wide and 4mm thick. It is an ND filter with a 32x filter factor that provides a 5-stop exposure reduction. This filter's 1.5 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 1.5 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. Does it fits 4"x4" Tilta Mattebox?

A: No, the Haida 100 x 100mm Circular Polarizer Filter will not fit the Tilta Tiltaing Mini Matte Box 4"x4", the Haida 4 x 5.65" V-Pro Series C-POL Polarizing Filter (BH #HAVPCP45) will.

Q: 2. I assume to use this you have to rotate the whole mounting assembly. Yes? How easy is this to do? Does this scratch up the lens housing?

A: This filter is rotated in the holder and is smooth functioning and does not scratch the housing.

Q: 3. How many light steps does it represent?

A: The Vaxis VFX 95 IRND 2.1 Filter for Tilta Mirage Matte Box would reduce the light by 7 stops.

Q: 4. Why is it MORE expensive to buy just the filter without the adapter included?

A: While Canon sets the MSRP on their items, as of the time/date of this reply, the cost of the Canon Drop-In Variable ND Filter A (1.5-9 Stop), BH #CADIVNDFA, and the Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter, BH #CAMAEFRFDIND, on our website are currently the same price. However, I would simply recommend that if you are certain that you want the Variable ND Filter, as it is the most expensive of the filter options that are compatible for use with the Canon Drop-In Filter Mount Adapter EF-EOS R, I would simply recommend to purchase the adapter kit that comes with the Variable ND filter, the Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter, BH #CAMAEFRFDIND.

Q: 5. Will this fit the Lee 100mm filter holder?

A: This filter will indeed fit the filter holder

Q: 6. Does the variable ND drop in filter fit in the Canon ef -R 0.71 speed booster?

A: No, the Canon Mount Adapter EF-EOS R 0.71x (seen here: https://bhpho.to/3OmrCw5) does not accept the Canon Drop-in Variable ND Filter A.

Q: 7. Will this drop in the Canon 300mm 2.8 just like the Polarizer Filter will?

A: Canon Drop-In Variable ND Filter A (1.5-9 Stop) is compatible only with the Canon Drop-In Filter Mount Adapter for EF-EOS - R lenses. It will not fit on Canon EF 300mm f/2.8L IS II USM Lens. You can use fixed ND filters with the following product: 1-Canon - Drop-In Filter Holder for 52mm Screw-In Filters BH #CAFHS52 https://www.bhphotovideo.com/c/product/186092-REG/Canon_2612A002_Drop_In_Filter_Holder_for.html/accessories

Q: 8. Is there a non-variable ND drop in filter for this mount? Like a set of multiple NDs? I can't stand the color shift and increased contrast variable NDs create. I'd much prefer to just carry around a few drop in's at varying ND levels

A: We're afraid not. At this time Canon does not offer any alternative ND Filters for this system.

Q: 9. Is the filter holder included?

A: No. Just the following is included. VFX Filter Alcantara leather bag

Q: 10. How many stops is this?

A: The Vaxis 95 IRND 2.1 filter has an optical density rating of 2.1, which equates to a 7-stop reduction in f-stop reduction.
