Perfect for landscape applications and greater control over your exposures, the 46mm 7artisans ND Filter 46mm 3-Stop for Photographyis a solid 3-stop ND that enables working with a wider aperture or slower shutter speed than usually required. By slowing your exposure time or increasing your aperture, you can to control depth of field. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters. The ultra-slim aluminum ring helps prevent vignetting when filming with wide-angle lenses or stacking multiple filters.

• ND8 filter provides a 3-stop light reduction, which allows for longer exposures and motion blur techniques, and is perfect for landscape applications and controlling exposure when used during video recording.
• Double-sided, 24-layer coating reduces reflections on the filter's surface, resulting in greater clarity and contrast.
• Nano coating is water, scratch, and oil resistant and easy to clean.
• Filter features K9 optical glass and a slim 6061 aluminum alloy ring.

Related Questions and Answers

Q: 1. Does this create vignetting on the Voigt 40mm f/1.2 on a Leica M?

A: No, this filter should not cause vignetting on a 40mm lens.

Q: 2. with an ultra-wide angle lens (i.e. Canon 16-35mm F4L with a full frame camera), do you get the dreaded X show up and if so at what density does it show up?

A: The X you can sometimes pick up in the image with a variable ND filter is caused most of the time by variable ND filters that go over 7-8 stops and lower quality ones.The B+W filter is fine. The one thing you might pick up is when set to the widest setting on that lens, 16mm you might pick up some vignette. And that is going to happen with that lens with most filters because of how wide it can go. The filter is designed with a thinner frame so it should be somewhat minimal.

Q: 3. Can someone explain the markings on the filter? Thanks

A: The markings are 1/2 stop increments. This helps you determine the proper exposure.

Q: 4. 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: 5. Does the ring physically stop at min and max ends, or does it just spin all the way around?

A: Yes! Hard stops on both ends. Great feature.

Q: 6. Does this filter come with an 82 mm front cap?

A: Received only the filter without cap

Q: 7. Has anyone used this filter with the DJI X5 camera? If so, how is the color fidelity? Is there any specific color cast? Thank you.

A: B+W make very high quality filters. This will give you a great performance when used on lens with the X5.

Q: 8. How thick is this filter?

A: I don't have this filter. Not sure why I was asked by BH to answer the question. Sorry.

Q: 9. 82mm. Does this filter have "front threads", for instance to screw on a lens hood?

A: The following system offer 86mm Front Filter Threads.

Q: 10. Can I use a this filter for a Canon 24-105mm and Sigma 18-35mm lens?

A: Yes, but you need one more part to make it fit. You'll need what's called a step-up ring. Your Canon lens is a 77mm filter thread size and you need a step-up ring (super cheap to buy) that spans the difference (a 77mm to 82mm ring). Same for Sigma - need to find a 72-82mm step-up ring or you may have to buy two, a 72-77mm and a 77-82mm. You can shop for them here.
