K&F Concept 40.5mm Magnetic 3pcs Filter Kit

The K&F Concept 40.5mm Magnetic 3-Piece Filter Kit combines MCUV, CPL, and ND1000 filters with a magnetic adapter ring for lightning-fast 1-second swaps. Made with premium AGC optical glass and 28-layer coatings, it ensures glare reduction, lens protection, and stunning long-exposure effects without vignetting.

Take your photography and videography to the next level with the K&F Concept 40.5mm Magnetic 3-Piece Filter Kit. This versatile kit includes a MCUV filter for lens protection and accurate color fidelity, a CPL (Circular Polarizer) to remove glare and boost contrast, and a ND1000 neutral density filter to create smooth long-exposure effects.

Thanks to the magnetic adapter system, filters attach and swap in under one second, allowing rapid adjustments in dynamic shooting situations or cold environments. The ultra-slim CNC-milled frame (1.93.5mm) prevents vignetting even with 16mm wide-angle lenses, while the non-slip design ensures secure handling and easy installation.

Constructed from imported AGC high-definition optical glass with 28-layer multi-coatings, these filters are hydrophobic, scratch-resistant, oil-proof, and free from color shifts. The kit also includes a magnetic adapter ring and a protective pouch, making it a portable, convenient solution for creative photography, landscapes, and portraits.
