Freewell K2 Versatile Magnetic Filter System
Freewell’s K2 system builds on the brand’s modular magnetic approach and stands out for its ability to host optional filters such as Gradient, Mist, Streak, and Straight ND within a single, swappable assembly. This design accelerates gear changes during changing light, letting you adjust exposure or texture without hunting for threaded rings. The K2 is described as futureproof: it covers lens sizes up to 82mm with included adaptors from 67mm to 82mm and offers additional adaptors for 52–62mm. The setup reduces the need for multiple thread-size filters while maintaining quick access on location.
Color fidelity is reinforced by Freewell’s TRUE COLOR coating, aiming to minimize color shifts when stacking ND or VND filters. The magnetic interface is designed for reliability in the field, with sturdy construction and quick releases that help keep up with dynamic shots. For landscapes and run-and-gun video, this kit’s flexibility—coupled with broad compatibility—reduces gear-switching friction that can disrupt a shooting cadence.
NiSi JetMag Pro 82MAG Landscape ND Magnetic Filter Kit
NiSi’s JetMag Pro system delivers instant, thread-free swaps with a patented twist-lock design for secure attachment. The 82mm-diameter magnetic ND filter and CPL filter stay stable even during fast-paced shoots. The kit includes four filter adapters (67mm, 72mm, 77mm, and 82mm) to cover multiple lenses, ensuring quick setup on the fly. This combination of ND and CPL options streamlines exposure control and glare reduction without the risk of cross-threading, making it a versatile choice for travel and on-location work.
The ND options (ND8, ND64, ND1000) provide 3-, 6-, and 10-stop light reduction, enabling longer exposures or shallower depth of field in bright light. The True Color CPL helps reduce reflections on non-metallic surfaces while preserving accurate color. A silver-coded handle allows smooth rotation and quick adjustments, giving full control over the polarizer during dynamic lighting conditions.
Freewell 82mm Magnetic Versatile VND System
Freewell’s 82mm VND system combines variable neutral density with additional magnetic options, delivering a comprehensive range of exposure control in a single mount. The VND2-5 and VND6-9 blocks cover common video and still photography needs, while built-in CPL and ND32/CPL options extend control. The kit also includes dedicated Mist modes such as VNDMIST2-5 and VNDMIST6-9, along with GLOW MIST for cinematic texture. This broad feature set supports both photography and videography across changing lighting scenarios.
Optics use 18-layer multicoated, high-definition glass, and a CNC-machined metal frame with magnets for durability in field use. The system provides smooth, repeatable control with minimal color shifts, making it suitable for both landscapes and run-and-gun shoots in bright sun or rapidly shifting skies.
K&F Concept 77mm Magnetic CPL+ND8+ND64 Kit
This magnetic kit completes a compact yet capable filtration setup in a 77mm form factor. A magnetic adapter ring enables around-the-second swaps, letting you change filters in under a second without threading. The set includes CPL for glare control and ND8 (3 stops) plus ND64 (6 stops) for exposure flexibility, especially on partly cloudy or bright sunny days. The Nano-X Series coatings and 28-layer protection help preserve color and contrast while keeping coatings durable against the elements.
The kit is designed for travel and field use, offering quick access to essential effects without bulky gear changes. The combination of CPL with two ND options makes it a strong choice for urban and landscape shooters who demand rapid adjustments while maintaining image fidelity.
Freewell M2 Magnetic Quick Swap 5-Pack 82mm Filters
The M2 kit marks an upgraded magnetic quick-swap system designed for rugged outdoor shooting. It includes a new lens cap with a holder for convenient access and a 5-pack of essential filters. The lineup comprises ND8, ND64, ND1000, CPL, and UV, covering both still photography and video workflows across varied lighting conditions. The M2 is built for field reliability, enabling rapid exposure control while protecting optics during travel and remote shoots.
Built around premium German optics and multi-layer coatings, these filters are described as scratch-resistant, waterproof, dustproof, and oil-resistant. The magnets and CNC metal frame provide durability in challenging environments, while the refined surface coatings help preserve edge-to-edge sharpness and color accuracy in bright or coastal light. This kit offers a balanced entry point for shooters who want a versatile, all-in-one magnetic system.
Buying Guide
Compatibility And Quick Swaps
Choose a system that matches your most-used diameters and lens lineup. Look for kits that include adapters covering a wide range (for example, 67mm–82mm) or offer inexpensive add-ons for smaller sizes. A magnetic interface should provide secure retention with smooth, repeatable swaps to keep up with changing light without hunting for thread rings.
Filter Library And Creative Options
Consider which filter types matter most. ND filters (ND8, ND64, ND1000) are essential for long exposures and bright scenes. VND options let you adjust exposure on the fly without changing composition, while CPLs remove glare. Mist, Glow Mist, and Streak effects add texture or mood but may alter color in ways you’ll want to evaluate in advance. A versatile kit that blends ND, VND, and CPL options typically serves most shooting styles.
Optical Quality, Coatings, And Color Fidelity
Assess the glass quality and multi-layer coatings, as these determine glare reduction, color accuracy, and edge-to-edge sharpness. Look for terminology such as “multicoated,” “TRUE COLOR,” or high-layer counts that indicate strong performance against reflections and color shifts. Kits built with robust coatings help maintain natural hues in skies and skin tones, especially at wide apertures or during long exposures.
Durability And Ease Of Use
Durable construction—prefer CNC-machined metal frames and strong magnets—supports field use, travel, and outdoor conditions. Easy-to-use designs minimize the time spent swapping components, which is especially important when working with changing weather or dynamic scenes. Consider weight and balance on your lens system if you frequently shoot handheld or on gimbals.
Value, Investment, And Lens Compatibility
Evaluate the overall value by weighing the number of filters included, the range of diameters supported, and potential costs for extra adapters. A modular system that reduces the need for multiple threaded filters can save space and time, particularly for shooters who cover varied lenses. Ensure compatibility with your most-used lenses to maximize return on investment without sacrificing image quality.
