- ND2-32 provides 1–5 stops of light reduction
- Not compatible with other K&F Concept magnetic systems of different sizes
Best for: new users and compact kits. Limitations: size-specific compatibility means you should match to your lens diameter; expansion to other sizes requires additional gear.
K&F Concept 49mm Magnetic CPL+ND Kit
The 49mm Nano-X kit mirrors the 77mm setup in a smaller size, delivering rapid one-second swaps with CPL and ND filters. It’s best for compact bodies or kit lenses where 49mm is the natural fit. The CPL clarifies scenes with blue skies and reduces reflections on water or glass.
- 1-second swap; magnetic adapter ring plus filter
- ND8 and ND64 for 3- and 6-stop reductions
- Color and contrast enhancement via CPL
Who should buy: hobbyists and budget-conscious photographers using small-diameter lenses. Caution: may require separate rings for other lens sizes and compatibility checks with multi-brand magnetic systems.
K&F Concept 6.1 Inch Magnetic 67mm Filter Mount
This mount attaches a 67mm variable ND2-32 with magnetic ease and supports attachment to iPhone devices via a 6.1-inch filter mount adapter. It enables quick exposure control for moving subjects and scenic shoots, while supporting accessory expansion with magnetic compatibility on both sides.

These 82mm caps are designed for magnetic swap systems, providing dual magnetic and threaded compatibility. They protect lenses from dust, fingerprints, and impact while ensuring a secure fit for larger filter diameters. Suitable for professionals who swap frequently and require dependable protection.
- Magnetic and threaded dual connection
- Primarily for lens front-element protection
- Durable magnesium alloy build
Best for: photographers needing extra lens protection with a secure, dual-fit cap. Limitation: not a filter itself; must be used with a compatible magnetic swap system.
Buying Guide: Magnetic Lens Filter System Essentials
- Compatibility: Check your lens diameters and whether the kit’s adapters cover your lens lineup. Magnetic systems often come in specific sizes (e.g., 67mm, 77mm, 82mm).
- Swapping speed: Magnetic rings and snap-on filters dramatically reduce swap time, which helps capture unpredictable moments.
- Filter types: A CPL improves color and reduces glare; ND filters control exposure; VND offers variable density for flexible exposure settings.
- Image quality: Look for multi-layer coatings and optical glass to minimize color cast, halos, or vignetting—especially on wide-angle lenses.
- System stability: A secure magnetic connection matters during movement; consider weight, mount strength, and whether the kit stays in place with fast action.
- Portability: If you shoot on the go, a compact kit with a storage case helps reduce bulk while preserving quick access to filters.
- Durability: Magnesium alloy caps and robust builds protect gear in travel environments and busy shoots.
FAQ
- What is a magnetic lens filter system?
– It uses magnets to attach filters quickly to compatible rings, enabling fast swaps without twisting on/off threaded filters. - Which kit is best for travel photography?
– The 77mm or 49mm Nano-X magnetic kits are ideal for travel due to compact sizes and quick-change capability. - Do magnetic filters affect image quality?
– High-quality magnetic filters with multi-layer coatings can maintain color accuracy and sharpness, though lower-cost options may introduce slight color shifts. - Are all brands compatible across sizes?
– No. Magnetic systems are typically size-specific; ensure you have the right adapters for each lens diameter you own. - Should I choose ND or CPL first?
– If you shoot landscapes or water scenes, start with ND for exposure control; add CPL for glare reduction and color enhancement as needed.
