This 1- to 5-stop K&F Concept Nano-X Green ND Filter 43mm 1-5 Stopfrom K&F Concept Nano-X Green ND Filter 43mm 1-5 Stopis a 43mm variable neutral density filter providing an adjustable light reduction of 1 to 5 stops. It darkens the entire image evenly, allowing a photograph to be made with a wider aperture or slower shutter speed than normally required. By slowing the exposure time or increasing the aperture, it is possible to control the depth of field and create motion blur, creating a dynamic look for streams, waterfalls, landscapes, and more. This multicoated variable neutral density filter does not affect the color of the image, and it features a waterproof and scratch-resistant coating for durable performance in the field.

Related Questions and Answers

Q: 1. Can a lens hood be used with this filter, specifically for a sony 24-70 2.8 v1?

A: No, the Nano-X Variable ND filter will not work on the Sony 24-70mm f/2.8 GM I with the lens hood on. Both the polarizing and variable ND knobs on the filter prevent the lens hood from mounting on the camera. If you use fixed ND filters, you can use the lens hood.

Q: 2. Can I put it on a sigma 30 mm lens?

A: In theory you could with a step down ring, but you'll get vignetting on the edges. I'd recommend getting the correct 52mm filter.

Q: 3. What does the "green" do?

A: The K&F Concept Nano-X ND2-ND32 Green Multicoated Variable ND Filter's coating is used to neutralize color temperature deviations that occur under certain lighting conditions. This helps with color balance, reducing light loss, and managing reflections that would affect the contrast of the overall image.

Q: 4. Would I be able to mount another filter like a mist filter in front of that?

A: The K&F Concept Nano-X Variable ND8 to ND128 Filter (52mm) has no front filter threads, so you would not be able to mount another filter on the front of this filter.

Q: 5. Can this be safely used for photographing a Solar Eclipse?

A: I would recommend 17 stops or more for solar eclipse, so I wouldn't recommend the K&F Concept Nano-X Series ND32000 ND Filter (100 x 100mm, 15-Stop) for solar eclipse.

Q: 6. We know the rear filter threads, can we get an official filter thread sizes for the front?

Q: 7. I have a Canon 24-105mm f4L(77mm). I already have a 77mm protective filter on it; with threads, so I can stack another filter. What size ND filter should I order?

A: Protective filters have the same size front and rear threads so a 77mm variable ND would be recommended.

Q: 8. Do these filters have cross polarization X?

A: No, they don't.

Q: 9. Can the orange lens handles be removed? Thanks

A: The orange handles of the K&F Concept Nano-X Pro Series CPL+ND2-32 Filter (77mm, 1 to 5-Stop) are not made to be easily removed, but they can be removed with a screw driver (purchased separately).

Q: 10. Are these filters glass or resin?
