The Sigma 18-35mm f/1.8 DC HSM Art uses a 72 mm filter thread, so select 72 mm screw-in filters or use a correctly sized step-up system. Fixed NDs lock one strength; variable NDs trade convenience for the need to inspect footage or stills for uneven darkening, color shifts, and cross-polarization at strong settings. Coatings and price do not guarantee image quality. Avoid unnecessary stacking, which can increase vignetting and reflections.

The picks, in detail
Tiffen 72mm ND 0.9 3-Stop Filter
Fixed 3-stop screw-in ND listed in 72 mm. A fixed ND avoids variable-ND cross-polarization but needs a separate filter when you need another strength.
- 72 mm thread
- fixed 3-stop
- screw-in
- simple fixed strength
- no VND rotation
- one strength only
- can stack with care
NiSi PRO Nano IRND 72mm 10-Stop
Fixed 10-stop 72 mm IRND for long-exposure work. Use a solid case and avoid stacking unless you have checked for vignetting with the lens hood and composition.
- 72 mm thread
- fixed 10-stop
- IRND coating
- strong fixed reduction
- coated glass
- slow to compose through
- not variable
K&F Concept Nano-X 72mm 2–6 Stop VND+CPL
72 mm variable ND/CPL combination listed in the 2–6-stop range. Its rotation is convenient, but wide settings may show uneven polarization or color shifts depending on scene and angle.
- 72 mm thread
- 2–6 stop variable
- CPL combination
- one rotating filter
- moderate range
- cross-polarization possible
- not ideal for stacking
Hoya PRO ND8 72mm
Fixed 3-stop Hoya PRO ND in the 72 mm size. A fixed filter is useful when the planned exposure reduction is known in advance.
- 72 mm thread
- ND8 / 3-stop
- fixed density
- simple control
- no rotation artifacts
- one density only
- requires separate strengths
Hoya PRO ND64 72mm
Fixed 6-stop Hoya PRO ND for 72 mm lenses. It is a separate density choice, not a replacement for a variable ND when light changes quickly.
- 72 mm thread
- ND64 / 6-stop
- fixed density
- deeper fixed reduction
- screw-in format
- one strength
- may require live-view composition
B+W XS-Pro MRC Nano ND 0.9 72mm
Fixed 3-stop 72 mm filter with multi-resistant coating. Coating reduces handling concerns but does not guarantee flare-free or color-neutral images.
- 72 mm thread
- 0.9 / 3-stop
- MRC Nano coating
- fixed density
- coated surface
- premium price
- one strength
PolarPro Peter McKinnon PMVND II 72mm 2–5 Stop
Variable 2–5-stop ND in the 72 mm size. Use marked stops as a starting point and examine footage for exposure or color changes rather than relying on the ring alone.
- 72 mm thread
- 2–5 stop variable
- rotating ring
- fast adjustment
- moderate VND range
- variable-ND artifacts possible
- larger front profile
Moment Variable ND 72mm 2–5 Stop
A 72 mm variable ND in the 2–5-stop range. Keep it as the only front filter where possible; stacking rotating filters can cause mechanical interference and vignetting.
- 72 mm thread
- 2–5 stop variable
- rotating control
- single-filter adjustment
- moderate density
- cross-pattern risk at extremes
- not a fixed-ND substitute
Urth 72mm Variable ND2–ND400
72 mm variable ND with a broad ND2–ND400 range. The wide range makes it flexible but requires checking for cross-polarization and uneven darkening at stronger settings.
- 72 mm thread
- variable density
- rotating front ring
- wide adjustment range
- single filter
- strong settings need inspection
- no image-quality guarantee
Buying tips
- Use the lens’s 72 mm front thread; do not buy a filter based only on focal length.
- Fixed NDs are simpler for known exposures; variable NDs need testing through their full rotation.
- Inspect strong variable-ND settings for cross-patterns or uneven skies, especially with wide compositions.
- Avoid stacking ND, CPL, and step rings unless you have checked clearance, vignette behavior, and reflections.
