This 62mm Ice Soft-Edge Graduated ND Filter helps darken specific areas of an image while allowing for a normal, unaffected exposure in the other parts. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the two areas. This filter is particularly useful for images that do not have a strongly defined transition between the sky and foreground.

The filter features glass optics and an aluminum filter ring threaded on both sides. A rotating ring allows precise positioning of the gradation along the horizon line.

Q: 1. Want to use it to cut down ambient light and light the subject with monolight. How well does this work for portraits ?

A: The Ice CO Nano Multi-Coated 1.8 ND64 Filter (77mm, 6-Stop) will provide a 6-stop exposure reduction. You can use your lens aperture wide open under the bright daylight setting, while controlling highlights and shadows with monolights.

Q: 3. Can you confirm this filter can be used to film the solar eclipse? What's the total time frame?

A: The Marumi 77mm DHG ND-100000 Solid Neutral Density 5.0 Solar Eclipse Filter (16.5 Stops) is unsuitable for photographing the solar eclipse. The filter does not cut harmful IR and UV light.

Q: 4. 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: 5. Do these filters have cross polarization X?

A: No, they don't.

Q: 6. Does this have threads on the front side too? I'd like to attach a lens hood

A: Yes, this does have front filter threading. You can attach a lens hood to this filter.

Q: 7. Is this filter, ND100,000 safe to photograph the sun? For a prolong period like a solar eclipse , 4-6 hours?

A: 4-6 hours is a lot. Usually an eclipse you take a photo that is fractions of a second. This ICE Magco Solar filter does not list reducing UV and infrared. If you plan on doing long exposures of the sun I recommend a filter that reduces UV and infrared like this one DayStar Filters 90mm White-Light Universal Lens Solar Filter https://www.bhphotovideo.com/c/product/1319794-REG

Q: 8. 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: 9. Seems thick. Will it vignette? Depending on lens I suppose. Also, will it interfere with lens hood?

A: If your lens is wider than 24mm (full frame), then yes it will probably vignette. It would most likely interfere with the hood.

Q: 10. Is it stackable

A: No, the K&F Concept Nano-X ND2-32 Variable Fader & Circular Polarizer HD Green Coated Waterproof Anti-Scratch Japan Optics Filter (77mm) does not have filter front threads.
