This 1 to 5-stop 82mm Nano X-Pro Magnetic Variable ND Filter from K&F Concept is an adjustable neutral density filter with a 1 to 5-stop exposure range that can easily control the amount of light entering the lens for finer image control. The filter density is easily changed by rotating the filter ring, and the advanced optical design prevents the "X" pattern found on lower-quality filters from appearing on the image.

This filter darkens the entire image area evenly, allowing a photograph to be made with a slower shutter speed or wider aperture without overexposing your image. Slowing the shutter speed increases the exposure, making it possible to increase motion blur to emphasize motion, such as when shooting flowing water. Alternately, increasing the aperture provides finer control over depth of field, useful when trying to isolate the subject. This adjustable filter is especially useful when shooting landscapes and in very bright conditions and can be used for both still and video imaging. Adjusting filter density also makes it possible to control frame rate when shooting video.

This optical glass filter features a 28-layer nano-coating to reduce potential flare and glare, and for optimal resolution and color transmission. It also provides a resistance coating that repels oil and water, plus minor scratches, and abrasions, making suitable for use on location even in harsh environments. This durable aluminum-magnesium alloy filter ring includes magnetic adapter ring that fits lenses with 82mm filter threads, allowing it to be attached and exchanged in seconds.

Q: 1. What does different between B+W 82mm T-PRO UV Filter BH #BWUVTP82 • MFR #1097759 ?

A: The B+W 82mm T-PRO UV Filter is a slim filter that helps prevent vignetting on wide-angle lenses.

Q: 2. Can this EF-RF adapter accept the Canon Super Telephoto drop-in filter holders?

A: Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter has a built-in/ non removable Nd filter. There are no threads either to screw additional filters. The drop in filter magazine is also smaller than the standard telephoto drop in filter. It's dimensions are 6mm x 53mm x64mm.

Q: 3. What is the light transmission with this filter?

A: The light transmission of the B+W 010 UV Haze MRC Nano Filter (77mm, Special 50th Anniversary Edition) varies with the wavelength of the light. You can find the percentage of light transmission vs. wavelength graph here: https://bhpho.to/3s4AS23.

Q: 4. Is this compatible with RF lenses? If not has Canon mentioned if there will be an adapter for RF lenses on the R? And if not are there alternatives?

A: This is only for EF lenses. I am not aware of any alternatives.

Q: 5. Does this VND cause the "x"?

A: None that we can see. The ND stopped all the way down looks great with no X over the video.

Q: 6. Will this help dissipate heat for the Canon R5?

A: No.

Q: 7. I am more concerning the image quality and autofocus speed when using this variable ND filter. Does it degrade the image quality or add othe color tone(s) or hue(s) to the captured image? Does it slow down the autofocus speed at all?

A: It works well , The darker the ND the slower the focus usually it gets , but in Mirrorless Digital Camera its not as bad , and it does not have a color shift

Q: 8. Are there front threads and if so, what is the diameter?

A: The B+W 010 UV Haze MRC Nano Filter (95mm, Special 50th Anniversary Edition) has 95mm front threads.

Q: 9. Will it work on the Canon EOS C70

A: This would work on the C70.

Q: 10. Is there a version of the drop-in filter mount that adopts PL lenses to RF?

A: This Fotodiox adapter is for PL lens to Canon RF camera and it has a built in ND filter. The filter is not drop in though. There isn't a version with drop in for that combination. https://www.bhphotovideo.com/c/product/1486458-REG/fotodiox_pl_eosr_ndthrtl_cine_vizelex_nd_throttle_lens.html
