As a casual photographer who enjoys snapping pictures during vacations and family gatherings, the K&F Concept Magnetic UV Filter has been an absolute game-changer for me. The package includes a magnetic UV filter and a microfiber cleaning cloth, which makes it incredibly convenient to swap filters in just one second. The threaded part stays securely on the lens, and the magnetic part allows for quick addition of other K&F Concept magnetic filters. I keep this one on and then I don't have to worry so much about a lens cap while I'm shooting. Obviously I still use a cap when traveling and transporting, but this filter protects the glass just fine.This UV filter not only protects my lens from dust and scratches but also effectively absorbs UV rays, eliminating the blue tone in my photos and ensuring clear and vibrant images. The imported Japanese AGC glass used in the filter delivers razor-sharp images while maintaining the true colors of my shots. Plus, the ultra-slim frame prevents any vignetting on my wide-angle and telephoto lenses, which is a huge plus!The NANOTEC coating is another standout feature, providing 94% light transmission and significantly reducing reflections. This ensures that my images remain true to their colors, even in challenging lighting conditions. Just make sure to verify your camera's lens thread size before ordering – it’s clearly marked next to a "Φ" symbol on the lens. For instance, Φ67 means a 67mm lens thread size. Overall, this magnetic UV filter has enhanced my photography experience, and I highly recommend it to any fellow casual photographer looking for an easy and effective lens protection solution.
