K&F CONCEPT 77mm Variable ND2-400 Lens Filter (FN101)
This 77mm variable ND filter uses import optical AGC glass with eight multi-layer coatings to minimize reflections and glare. It offers 1 to 9 stops of light reduction and a 360-degree rotation for precise dimming settings. A caution: high stops can cause a cross-pattern “X” effect with certain lenses and focal lengths; this is a known, temporary issue when using strong ND settings and adjusting the frame. The surface features an oxidized sandblasting finish to reduce stray light on the metal body.
Best for: Photographers needing heavy light control, especially in bright landscapes or daytime video. This option is well-suited for users who value color fidelity and glare reduction, while accepting the potential cross-pattern at maximum stops as a normal behavior under some conditions.
Caution: Be mindful of potential X-cross at higher stops; plan framing accordingly or reset to mid-stops for a clean image.
K&F CONCEPT 77mm True Color ND2-32 & Polarizer (FA702)
This 1-5 stop variable ND and CPL combo helps darken bright skies while reducing reflections from non-metallic surfaces. It uses imported AGC optical glass with 28 multi-layer coatings for durability and high-definition results. A key advantage is avoiding the X-cross problem on images thanks to self-locking design and smooth infinite rotation. Old and new packaging may vary, but the contents remain consistent.
Best for: Shooters who want both light reduction and glare control in one compact filter, especially when landscapes include water or glass surfaces. Choose this if you need a convenient two-in-one solution without swapping between separate ND and CPL filters.
Limitation: Some users may encounter minor packaging variation; verify current contents upon receipt.
K&F CONCEPT 77mm Side Lever ND ND2-400 (FN722)
Equipped with a putter-style frame for precise stop adjustment, this lens filter offers full-range 1-9 stops with a 360-degree rotation. The eight-coat AGC glass reduces glare, while a multi-layer hydrophobic, oil-proof, and scratch-resistant coating protects both sides. It’s designed for adventurous use, including outdoor shooting where wind, dust, or moisture may be present.
Best for: Videographers and photographers who need quick, tactile control over stops during dynamic shoots. The lever design helps position lighting precisely when scenes shift rapidly.
Caution: The lever mechanism adds a slightly unconventional feel; ensure it remains secure during travel to avoid inadvertent rotation.
K&F CONCEPT 77mm ND2-32 & CPL (FN712)
This 1-5 stop variable ND alongside a CPL provides comprehensive control over daylight exposure and reflections from non-metallic surfaces. It uses imported AGC glass with 28 multi-layer coatings to preserve image quality while reducing glare. The design avoids the X-cross problem common with some variable ND filters, thanks to self-locking frame construction.
Best for: Social-content creators and outdoor photographers who want a single, affordable solution for ND and polarization, especially in bright environments with reflective skies or water surfaces.
Limitation: While designed to minimize color shifts, users should still test a scene to confirm color neutrality at different stops.
K&F CONCEPT 77mm ND2-32 & CPL (FA501)
This Nano-D series filter combines ND and CPL in a single unit with 24 multi-layer coatings for waterproof performance. It promises no color shift and high-definition image quality while offering 1-5 stops of light reduction. The self-locking frame minimizes the risk of “X” cross artifacts, providing smoother transitions when adjusting light reduction.
Best for: Content creators who want a compact, combined ND and CPL option for consistent color and reduced glare during daytime shoots on water, glass, or bright skies.
Limitation: The dual-function design can be slightly bulkier than a standalone ND or CPL in some setups; check your lens hood compatibility if using tight filter threads.
Buying Guide: 77mm Variable ND Filters
- Light reduction range: Most 77mm variable NDs range from ND2 to ND32 or ND2 to ND400. Choose a range that matches your typical shooting conditions—wide ranges offer flexibility but may introduce more pronounced color shifts or mechanical complexity.
- Cross artifacts: A common issue with variable NDs is the “X” cross at higher stops. Look for filters with self-locking frames and defined hard stops to minimize or avoid this problem.
- Coatings and glass quality: Multi-layer coatings (especially 28+ layers) and imported optical glass help reduce reflections and maintain image clarity. Hydrophobic and scratch-resistant coatings protect the filter in outdoor use.
- Polarizer integration: If you often shoot landscapes with water or glass, consider an ND+CPL combo to control glare and color without swapping filters.
- Rotation and control: A smooth 360-degree rotation with clearly marked stops makes exposure control easier, particularly for video where consistent shutter behavior matters.
- Build and durability: Frames with secure locking mechanisms and weather-resistant coatings help when shooting in challenging environments.
- Compatibility: Confirm 77mm thread size matches your lens collection. Some designs prioritize slim profiles to minimize vignetting on wide-angle lenses.
FAQ
- What is a variable ND filter used for? It provides adjustable light reduction to control exposure, enabling slower shutter speeds or wider apertures in bright conditions.
- What does ND2-400 mean? It indicates a range from 1 stop (ND2) to 9 stops (ND512). In practice, ND2-400 typically covers lower to very strong light reduction, depending on the model.
- Will all 77mm variable NDs cause X-cross artifacts? Not all, but some can at higher stops. Look for self-locking frames and defined stops to minimize this effect.
- Is an ND+CPL combo better than separate filters? It can be convenient for on-the-go shooting, especially when glare control is important, but may be bulkier and limit headroom for lens hood use.
- How do I avoid color shifts with ND filters? Choose filters with high-quality AGC glass and multiple coatings designed to preserve color balance across stops.
- Should I buy multiple ND values? If you shoot across varied scenes, a versatile ND2-400 and a mid-range ND2-32 pair can cover most conditions, with a CPL option if glare is frequent.
