I bought this K&F Concept variable ND filter kit for DJI Mini 5 Pro and was very happy with it. The package includes two filters: an ND2-32 and an ND32-512, covering practically every light condition, from cloudy skies to full sun days. The transition between the various density levels is smooth, with no shots or sudden changes in tone, making them perfect for videos and photos with controlled exposure. The optical quality is excellent: the lenses are sharp, do not introduce color dominants and effectively reduce reflections and flares, even in direct light. The anti-reflection effect and light transmission are really good, with a clean and natural final result. During the flights I did not notice vignetting or loss of definition, a sign of an excellent construction. The design is light and precise, it attaches perfectly to the Mini 5 Pro gimbal without altering its balance or interfering with stabilization. The materials transmit solidity, and the scratch-resistant and water-repellent coating is a detail that makes the difference during outdoor use. The kit comes in a well-made hard case, with a handy microfiber cloth included for cleaning the lenses. It is clearly a product designed for those who want to obtain more cinematic shots, controlling times and diaphragms in a professional way. In short, a set of very high quality filters, with excellent optical performance and impeccable construction. Perfect for those who use the Mini 5 Pro even in creative or professional settings and want to take their images to a higher level.
