NEEWER 37mm True Colors Variable ND & CPL Filter
Best for: Photographers who want a compact 2-in-1 solution combining variable ND and CPL in one threaded unit. The integrated CPL helps reduce reflections and boost color saturation in outdoor scenes. Use this when you want quick exposure control without swapping filters. Note: the hand knob design can prevent using a lens hood in some setups.
Why selected: It combines ND33 stops with CPL functionality in a single 37mm ring, offering portability and ease of use for travel shooters who carry minimal gear. The ability to switch to CPL while maintaining ND control is convenient in daylight or mixed lighting. The main limitation is potential X-pattern cross with certain lenses at maximum ND settings.
K&F CONCEPT 37mm Variable ND ND2-ND400
Best for: Travel shooters and beginners who want a broad 1-9 stop range with simple rotation. The 18-layer coatings reduce glare and keep color accuracy, while the compact build suits casual landscape or street photography. Beware of the potential X-cross at high stops with some lenses.
Why selected: It offers a wide exposure range with a clear stop-scale and a cap/cloth combo for maintenance, making it versatile for everyday use. The expectation is consistent color and moderate flare control. The main caveat is the common X-cross effect at the higher stops with certain lenses.
NEEWER 37mm Variable ND Filter ND3-ND1000
Best for: Photographers who shoot in variable light and need strong light reduction, including long exposure effects. The 1.5-10 stops range covers bright days to dim scenes, making it suitable for scenic waterfalls or cityscapes during midday. Cable-free hand-nut design enables precise adjustments.
Why selected: It provides a wide ND range and robust multi-coating for glare reduction. The double-sided coatings help protect the glass. A limitation is potential color shift or image softness at extreme stops on some lenses, so plan to test before critical shoots.
K&F CONCEPT 37mm Variable ND ND2-ND32 (No X Cross)
Best for: Those who want reliable no-X-cross performance with a one-to-five-stop range, suitable for everyday photography and beginners learning exposure control. It uses premium Japanese optical glass and multi-layer coatings to preserve color and reduce reflections.
Why selected: The no-X-cross claim addresses a common ND weakness, offering steadier results for practical scenes. Limitations may include a smaller stop range compared to higher-end variants, so choose this if you don’t need extreme stops.
NEEWER 37mm Variable ND + CPL + UV Kit
Best for: Content creators and beginners who want a compact kit with essential filters (ND, CPL, UV) in one package. The ND2-400 range supports a variety of scenes from landscapes to portraits under bright light. The CPL helps reduce reflections, while the UV offers basic lens protection.
Why selected: The three-filter set provides a practical starting point for those building a 37mm kit without shopping for multiple separate pieces. A limitation is that some users may outgrow the set as they explore higher ND ranges or lens compatibility across brands.
Buying Guide: Key Considerations For 37mm Variable ND Filters
- Filter size and compatibility: Confirm your lens thread size is 37mm. Verify if the filter design interferes with lens hoods or caps.
- Stops range: Decide how many stops you need. 1-5 stops cover casual adjustments; 1-9 or ND3-ND1000 offer stronger light control for long exposures.
- Optical coating: Look for multi- or dual-layer coatings to reduce glare, water, dust, and scratches, preserving color accuracy.
- X-cross risk: Some high-stop variable NDs can produce a cross-shaped artifact. Choose models with proven anti-cross designs if you shoot wide with fast lenses.
- Combination filters: 2-in-1 ND/CPL or 3-in-1 kits save space but ensure each element performs adequately and doesn’t cause color shifts.
- Build quality: Consider aluminum rings and knurled grips for easy handling in the field and secure mounting.
- Portability: For travel, a compact, lightweight filter with a protective case helps protect your investment and reduces bag weight.
- Maintenance: Clean with a microfiber cloth and avoid touching the glass with fingers to maintain clarity and filter performance.
FAQ
- What is a variable ND filter? A variable ND filter provides adjustable light reduction by rotating the filter, allowing you to change exposure without changing lenses.
- When should I use a 37mm variable ND? Use it when your lens has a 37mm thread and you want to balance exposure in bright scenes or create motion blur without changing filters.
- Is there a risk of color shift with ND filters? Some filters may cause slight color shifts; choose multi-coated options and test with your lighting conditions.
- What is an X-cross, and how can I avoid it? An X-shaped dark cross can appear at high ND stops on some lenses. Look for filters with anti-cross designs or limit stops in bright scenes.
