First of all, I am impressed by how well these filters are made. Each one is solid and durable, with a fluid thread that makes it easy to attach and remove them. I especially like the convenience of having multiple filters in a single kit, as well as the inclusion of two lens caps, which provide extra protection. The impermeability of the filters is a real asset for outdoor photography. I used this kit in foggy, rainy weather, and the filters worked perfectly without fogging up or losing clarity.

The CPL (Circular Polarizer) filter has significantly improved my landscape photos by reducing reflections and increasing color contrast, especially when shooting water, sky, or reflective surfaces. The UV filter is ideal for protecting against dust and scratches, while the ND1000 filter is a real asset for long exposure photography. It allows you to obtain silky effects on moving water and to capture movements without overexposing the image, even in broad daylight.

I am also impressed by the 24-layer coating on each filter, which adds protection against fingerprints, scratches, and smudges while maintaining optimal image quality. These filters don't create unwanted color casts, unlike other brands I've tried.

I have always been a fan of K&F filters because they offer consistent quality. This kit is perfect for a fast manual focus lens like the Zeiss 50mm f1.4 Planar Canon EF that I mount on my Sony camera via an adapter.

In summary, I would highly recommend this K&F Concept filter kit to anyone looking to improve their photography skills, whether hobbyists or professionals.
