This 3- to 11-Stop Nano-D Variable ND Filter with Multiresistant Coating from KF Concept is a 58mm variable neutral density filter that provides an adjustable light reduction of 3 to 11-stops. It darkens the entire image area evenly, allowing a photograph to be made with a slower shutter speed or wider aperture without overexposing the image. Slowing the shutter speed increases the exposure, making it possible to increase image blur to emphasize motion, as when shooting flowing water. Alternately, when 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 light conditions, and it is useful for both still and video imaging.

This ND8-ND2000 variable neutral density filter has a filter factor range of 0.9 to 3.3, providing an exposure reduction from 3 to 11-stops. It can help add motion blur and reduce depth of field when shooting still images, and to select a proper frame rate when shooting video.

The filter is made of Japanese AGC optical glass for the same high level of image quality as the lens it is used on.

Both the front and rear surface of this filter feature a multiresistant coating that repels dust and grime and protects for fine abrasions. The coating is also waterproof and oil resistant, making it easy to use and keep clean, even in hard environments.

The optical glass filter features a total 24 layers of multicoating for optimal light transmission and color saturation, without color shift.

The super lightweight CNC-machined filter ring is only 7.5mm thick, and it features a density scale for ease of use.

Q: 1. Will this filter interfere with the handle on my canon xf605?

A: The Opteka 58mm 0.3X HD Ultra Fisheye Lens Adapter will work with the Canon XF605's 58mm lens filter threads. You will probably need to remove the hood. We do not think it would hit the top handle.

Q: 2. This dolly, the Manfrotto Variable-Spread VR Tripod Dolly, (MDOLLYVRUS), appears to be virtually identical to the identical to the the 127VS Variable Leg Spread Portable Dolly, except for minor differences in the leg spread. Am I missing something here, or are their other differences I'm missing?

A: You really are not missing anything that we can tell. That appears to be the big difference.

Q: 3. Does Voigtlander Nokton 58mm f/1.4 SL II S Lens work with Nikon D5500's auto-exposure functions? I am guessing it won't autofocus but is it otherwise compatible?

A: You are correct, manual focus lenses like this will only prevent auto-focus and auto-aperture functions, but auto-exposure is handled by the camera and won't be prevented by the lens.

Q: 4. Is this removable?

A: Yes, it replaces the existing lens shim, if you remove it, just attach the original shim in its place.

Q: 5. Can I buy an autofocus adaptor for Nikon z6ii for this lens?

A: Currently, there is no autofocusing adapter for this lens. You will be able to use the Nikon FTZ II Mount Adapter with manual focus peaking.

Q: 6. I would like to use it on a Z7 body with the FTZ adaptor. Would the in-focus indicator work ?

A: This will support an in-focus indicator since it does have the electronic connection points.

Q: 7. Does it fit RF 600mm f4 IS USM?

A: Yes. as long as the lens is a 600mm f4 vriii and will also accommodate the 400mm 2.8 vriii lens.

Q: 8. What does this look like compared to the Cavision 0.35 fisheye?

A: The Cavision .35x Wide-Angle Fisheye Adapter Lens will provide a slighter wider image with .35x magnification compared to the Opteka 58mm 0.3X HD Ultra Fisheye Lens Adapter.

Q: 9. Can I focus this lens at max. Aperture f/1.4 when mounting it on the Nikon D750 or D810?

A: Yes, it is fully compatible with the D750 or D810.

Q: 10. I have the D800, I do a lot of video give me your thoughts?

A: The Voigtlander Nokton 58mm f/1.4 SL II S Lens would be a good lens choice for video usage on the Nikon D800 DSLR camera. The lens has smooth focus and has a built-in aperture ring. The aperture ring is not de-clicked, so it would be best to only use one aperture per shot, as adjusting the aperture may results in seeing the small steps in-between each aperture setting instead of a smooth transition. Otherwise, it would be a good standard prime focal length lens for your video recording needs.
