The 3-stop, 58mm Edge ND Filter from IRIX is an essential tool for landscape and long-exposure photography. This filter has an optical density of 0.9 and reduces incoming light by 3 stops, allowing more controlled motion blur and depth of field manipulation.

This optical glass filter features waterproof and oil-repellent nanocoating to prevent stains and fingerprints, allowing it to be used in extreme weather conditions. The low-profile frames and knurled edges provide excellent grip and functionality with a reduced potential for vignetting with wide-angle lenses.

Related Questions and Answers

Q: 1. Can I use this on my Nikon wide-angle lens 10-24mm without vignette?

A: Most likely, no. The rim on this filter being the variable midel, is much wider than a standard ND would be. You definitely need to find a fixed stop ND for a wide angle. Even with that, you may still have slight vignetting at the 10mm end.

Q: 2. is it possible to stack more filters on top?

A: According to information from Freewell, the front of this filter is unthreaded, meaning you won't be able to stack filters on top of it. You could mount some filters behind it, but we recommend not stacking too many as it could lead to unwanted results. Your mileage may vary.

Q: 3. are the filters glass or resin?

A: The filters in the Neewer 58mm ND, CPL, UV & FLD Lens Filter Kit with Accessories (6-Pack) are made of optical glass.

Q: 4. What is the widest focal length this can be used on with no vignetting?

A: I have the filter on my 24-70mm/f2.8 lens. So the widest is 24mm. I did not see any vignetting. I am very happy with this filter.

Q: 5. Does it have positive stops, detents, at each of the stops?

A: The K&F Concept Variable Fader ND2-ND400 Filter (62mm) doesn't have detents; it has markings for the stops on the edge of the filter.

Q: 6. Are they hard stops?

A: Yes the stops are hard on the K&F Concept Variable Fader ND2-ND400 Filter. You can feel the filter pause as you rotate it past each mark so you know how many stops you are blocking.

Q: 7. If I mount this filter holder on an Irix 15mm f2.4 lens using the Irix adapter for this lens (lens hood mount) and an Irix circular polariser in the lens filter screw mount, can I also use a 100x100mm 2mm thk ND filter in the holder?

A: If the circular polarizing filter has front filter threads, you would be able to attach the filter holder and use an ND filter in the holder.

Q: 8. Would this fit or which will fit a Sony A7 IV 28-70mm Lens?

A: You would need the 55mm version of the K&F Concept Variable Fader ND2-ND400 Filter (72mm).

Q: 9. 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: 10. Will it fit inside of the Canon 200mm f/2?

A: If your camera lens has a diameter of 52mm, then it should fit....The lens mm diameter is compatible with any filter with the same mm diameter it claims to have. Hope this helps!
