K&F Concept 72mm CPL & UV Filter Kit - Slim 28-Coating Set

Our review of the K&F Concept 72mm Circular Polarizers Filter & MC UV Protection Filter Kit finds it best suited to hobbyist and enthusiast photographers who want reliable lens protection and improved sky contrast without adding bulk. The kit pairs a CPL filter with an MC UV filter made from imported Japanese AGC glass and finished with double-sided 28 multi-layer coatings, delivering scratch resistance, hydrophobic performance and high transmittance so image clarity is preserved while managing glare and UV haze.

Key Features

• Imported AGC glass: Japanese optical glass provides a clear imaging surface and helps maintain sharpness when filters are used.
• 28 multi-layer coatings: Double-sided coatings reduce reflections and improve light transmission while making the surface easier to clean.
• Ultra-slim frame: The 3mm-5mm aviation aluminum frame minimizes vignetting on wide-angle lenses while remaining robust.
• MC UV protection: The UV filter reduces blue haze from UV rays and protects the front element from dust and scratches without degrading image quality.
• Circular polarizer action: The CPL cuts glare from non-metallic surfaces and boosts color saturation and contrast, especially in blue skies and clouds.
• Compact kit contents: The set includes a CPL, an MC UV filter, an up & down lens cap and a storage bag for transport and protection.

Who It's For

This kit is ideal for landscape and travel photographers who use a 72mm lens thread and want a lightweight, low-profile solution for glare control and everyday lens protection. The slim frame helps when shooting wide, and the coatings are useful for photographers who clean filters regularly.

Casual users who do not need two separate filters may find a single filter sufficient, and professionals seeking top-tier multi-coated glass with ultra-specialized anti-reflection stacks might look to higher-end pro series; still, this set offers a balanced mix of protection and optical benefit for most enthusiasts.

Pros & Cons

Pros

• Well-built optical glass with multi-layer coatings that resist scratches and make cleaning easier.
• Ultra-slim aviation aluminum frame effectively reduces vignetting on wide-angle lenses.
• The CPL enhances color saturation and reduces glare while the UV filter protects the lens without noticeable IQ loss.

Cons

• Some users report mixed experiences with ease of removal, so thread fit can feel tight on certain lenses.

Frequently Asked Questions

Will these filters cause vignetting on wide-angle lenses?
Because of the 3mm-5mm ultra-slim frame, vignetting is largely avoided on most wide-angle lenses, though very extreme wide setups should be tested.

Does the UV filter affect image sharpness?
The MC UV filter is specified to have about 99.6% transmittance and is designed not to reduce clarity or sharpness while offering protection.

Are the coatings durable and easy to clean?
The double-sided 28 multi-layer coatings include scratch-resistant and hydrophobic treatments that increase surface hardness and make cleaning easier.
