This 3-stop, 67mm HD MKII IRND Filter from Hoya features HOYA's exclusive ACCU-ND technology, which achieves equal reduction of the light in visible and IR spectrums. This added IR filtration eliminates issues with color shift in any shooting conditions, when compared to conventional ND filters.

Neutral density filters are important for filmmakers and photographers because they allow precise control over the amount of light passing through the lens. For filmmakers, this means shutter speeds that match camera frame-rate while maintaining creative depth-of-field control. Using a longer shutter speed makes it possible to increase motion blur to convey a sense of movement, or to dial in a video camera framerate. Increased density also makes it possible to shoot using wider lens apertures, helping to isolate a subject from the background.

The HD MK II IRND Series neutral density filters feature an anti-reflection multi-coating that reduces reflections caused by scattered light rays, which is an important concern during long exposures. In addition, a waterproof and oil repellent top-coat is applied for easy cleaning and maintenance.

The filter is mounted into a low-profile, lightweight, precision-milled aluminum frame. This frame design takes extra care to prevent light leaks and bleeding around the filter that may occur during long exposures. The slim filter frame can be used on most wide-angle lenses without vignetting. It features front filter threads for attaching additional filters or a protective lens cap.

If a single ND filter does not satisfy the requirement of the situation, or the photographer's vision, a combination of filters can be useful. For example: the combination of the HD MKII IRND 64 plus the HD MKII IRND 1000 will provide 16 stops of light reduction, enough to allow a camera to capture an image of the surface of the sun without overexposure.

Q: 4. Will the lens cap fit when using this filter with the Tamron 150-600mm f5-6.3 Di VC USD (for Nikon)? is the multi-coating on both sides of the glass? would you purchase again?

A: My filter is used on the Sigma 150-600, but it should work the same on Tamron, and yes, the lens cap does fit. Not sure if the coating is both sides or not, but I have had no problems at all with flare, ghosting, or sharpness degradation. Seems like an excellent product and I would buy again.

Q: 5. I have tried the Bower 95mm UV filter on my Tamron 150-600mm and I can't get the lens cap to fit properly with the filter on. The filter rim is not deep enough. Any recommendations?

A: I suggest using the Op/Tech USA Large Hood Hat, which will stretch to custom fit the Tamron 150-600 with a filter attached: http://bhpho.to/1qUpjke

Q: 6. will this work on cannon Rebel

A: It depends on the particular lens you have mounted on the camera. If you have the 18-55mm kit lens, then this would be the proper size for the lens. If you have a different lens, then remove the lens cap from the lens, and the underneath side of the lens cap will state the proper size filter you would need for that lens.

Q: 7. Will this filter work on any lens that is 95mm in diameter? Specifically a Sigma 50-500mm?

A: Yes, this filter will fit lenses with a 95mm filter thread size, including the Sigma 50-500mm lens.

Q: 8. Is there a version of this cable that is compatible with the Canon c70?

A: No these isn't one that support the canon c70

Q: 9. Does this work with the C300 Mark III?

A: Yes, the Tilta Nucleus-Nano Run/Stop Cable for Canon C200/C300 MkII (BH# TIRSLCT04CNC) has the correct 2.5mm connector for the Canon EOS C300 Mark III Digital Cinema Camera Body (EF Lens Mount) (B&H# CAC3003EF) and is compatible with it.

Q: 10. Would you be able to put a lens cap over top of this filter?

A: Yes
