Concept 77mm Center Split Refractive Filter Optical Glass Blur Effect Special Effect Filter with 3 Cleaning Cloths K&F (NANO-B Series)

📸【Blur Effect】The center split refraction filter can blur the foreground and create a blurred refraction effect. A blur effect is added on both sides to emphasize the subject of the photo, thereby creating a sense of layering and depth to the photo. Whether it's portrait photography or works of art, it can bring you a unique creativity and visual experience. 📸【K9 Optical Glass】 Adopts K9 optical glass with high light transmittance and excellent color reproduction function, ensuring photo clarity and image quality. 📸【Adjustable】The filter is rotatable and adjustable to meet environmental conditions. It is most effective when used with a large aperture, and we recommend keeping the aperture above F8.0. 📸[Perimeter processing] The outer frame of the special effect filter is oxidized sandblasted, which can effectively avoid stray light from entering. 📸 [3-piece vacuum packaging cloth included] The included cleaning cloth is made of microfiber and will not damage the coating of optical equipment such as lenses and lens filters. Even stubborn oil films and sebum stains can be easily removed. center focus filter
