The 46mm Graduated ND Filter from 7artisans Photoelectric allows you to balance exposure. The filter has the strongest effect/heaviest density at the outer edge of the filter, lessening-to-no ND effects at the center of the filter. This rotatable filter allows you to mount the filter on your lens and then align the graduation effect so you can photograph scenes with large bright areas, such as the sky, to achieve better cloud detail and color saturation, while maintaining proper exposure for your subject. Made of optical glass, each side of this glass features a waterproof, scratch-resistant, and oilproof coating, and the glass is polished to be flat on both sides so you can use it on wide-angle to telephoto lenses.

0.9 Optical Density    Water- and Stain-Resistant Coating    18-Multilayer Nano Coating    Made of K9 Optical Glass    6061 Lightweight Aluminum Ring

The filter is made of ultra-slim aviation aluminum glass with a non-slip CNC design. It easily installs on the lens with no vignetting or dark corners, even on wide-angle and telephoto lens.

The GND places the most density at the edge of the filter and tapers to clear by the center of the filter in order to accommodate photographing scenes with large, bright areas such as daytime sky.

With the GND, you can bring the picture to an exposure balance where you can avoid situations where the sky is too white, or the ground is too gray.

You can rotate the GND filter to achieve the appropriate effect. The front frame is threaded for use with multiple hoods, caps, and filters.

The Graduated Neutral Density (GND) Filter helps manage the lighting condition during golden hours, balancing the light between ground and sky to achieve better cloud detail and color saturation.

Both sides of the glass with double side polishing technology ensures high-quality images even on the telephoto lens. The gradient coating technology ensures uniform color and accurate stop-dimming without deviation.

This GND filter is made of optical glass. Each side of the glass is waterproof, scratch resistant, and oilproof. This makes it easy for cleaning and carrying and is suitable for all adventures.

Related Questions and Answers

Q: 1. How thick is this filter?

A: The profile is rather thin. It is similar to a typical UV filter in thickness. Which is actually thin considering all of the components involved in a variable ND. One thing to keep in mind: on my 16-35mm II (82mm filter), once mounted, it does not flush with the lens. It is slightly wider (3-4mm) than the tip of the lens. It can be pretty annoying if you're trying to mount a hood.

Q: 2. Can this filter fit the Sony 10-18mm wide-angle lens?

A: That is a very wide angle lens and I would suspect a vignette problem. The answer to that would be to buy a step-up ring and use the 77mm version of filter. Now you have a filter that will adapt to any lens you might have with the appropriate step-up ring. By the way, the 77mm and is often on sale for less than the 62mm.

Q: 3. will this properly fit the Leica 90mm f2,4 Summarit lens?

A: Yes this hood would fit on the Leica 90mm

Q: 4. Can you screw the B+W 77mm Kaesemann XS-Pro Circular Polarizer MRC Nano Filter on the front of this ND Vario?

A: I Can screw my B+W 77mm XS-Por ND-Vario 1-5 MRC nano into a NIKON 77mm Circular Polar 77mm filter and screw that on to my camera lens. The B+W XS-Pro does not have threads on its front side.McKinley

Q: 5. The description says that this filter features a thin, oversized mount which helps to reduce the likelihood to vignetting when used with wide-angle lenses. To use this filter with a smaller diameter lens, what step down ring size would I have to use to be able to use it on a smaller lens diameter - - 77mm or 82 mm to hold this filter?

A: The size step-up ring that would be required for use on your lens would depend on the filter size of your lens. Unfortunately, you did not list the lens you own or its filter size. As the B+W 77mm XS-Pro Digital ND Vario MRC nano Filter has 77mm rear filter threads, you would need a step-up ring that has 77mm front filter threads. If you need assistance with locating the proper ring for your equipment, you would have to send an e-mail to askbh@bandh.com with the above information and we will assist you with your inquiry.

Q: 6. Would this fit a Leica Summilux 15mm f 1.7 lens?

A: Yes, this should work fine with the 15mm 1.7.

Q: 7. anybody using this filter? Have you had any problems?

A: I've had it for a few months. Bought it because the Bower 95mm was just awful.... you get what you pay for! Personally, I've noticed no X pattern on this filter at all -- even at its highest level of filtering. I've not noticed too much of a color shift either....

Q: 8. Hello, is this metal or plastic? The photos shot two different designs, which is it?

A: This hood is made of metal with vents as represented in the 4th photo. the images will be adjusted on our site shortly.

Q: 9. How smooth is the rotation ring?

A: The rotation ring on this filter moves easily and smoothly--much better than most variable ND filters.

Q: 10. Does this filter vignette with a Panasonic 8-18 lens at 8mm with gh5s?

A: This is a 72mm filter, the Panasonic Leica DG Vario-Elmarit 8-18mm f/2.8-4 ASPH. Lens has a 67mm filter thread. Instead you would need BH #BWNDVXSP67 for that lens. https://bhpho.to/2YH9VNd
