I recently had the opportunity to try out the K&F Concept 43mm Variable ND Lens Filter, and I must say, I was quite impressed! The first thing that caught my eye was the self-lock frame, which eliminated the infamous ‘X’ cross issue often seen with variable nd filters on wide-angle and telephoto lenses. This feature alone made a significant difference in the quality of my photos. But the excellence didn’t stop there. The filter is made with imported AGC glass, ensuring a balanced color spectrum without any color cast or impact on image clarity and sharpness. The 28 multi-layer nanometer coatings, developed by K&F Concept’s optical engineers, provide waterproof, scratch-resistant, and anti-glaring protection for my valued lens. These coatings contribute to the high-quality photos I’ve been producing. The ultra-slim frame design also helps in avoiding vignetting, even with a 28mm focal length. The CNC-non-slip design makes it easy to install and remove the filter. One thing to note is that this filter kit is compatible with all 43mm lenses, so be sure to verify your camera’s lens thread size before ordering. I was also pleased to find that both new and old packages are sent randomly, ensuring a consistent experience for all customers. Overall, I am thoroughly satisfied with the K&F Concept 43mm Variable ND Lens Filter and would highly recommend it to any photographer looking to enhance their photography skills.
