Purchased in October 2024. Unopened but unused, as I sold the camera before using it. It has been stored in a dehumidified storage cabinet. All accessories are shown in the photos. Brand: K&F CONCEPT Material: Optical glass Photo filter thread size: 55mm Coating: nano_coating Photo filter effect type: Polarizing Photo filter size: 55mm 【Lens Filter Set】 Package includes: C-PL polarizing filter + UV protection filter + lens cap + cleaning cloth + filter case Compatible with 55mm size lenses. 【Polarization & Reflection Removal】 This PL filter enhances colors and controls reflections, allowing you to capture underwater scenes through water surfaces, reflections on water, and the transparency of wet leaves. For reflection removal, shooting at an angle rather than head-on will remove reflections more effectively. 【UV Absorption & Optical Glass】 The UV filter cuts ultraviolet rays and improves the contrast of subjects in strong sunlight. It can also be used as a protection filter. Multi-layer nano-coating and high-quality optical glass achieve high light transmission and bring out the original descriptive power of the lens. 【Middle Press Lens Cap】 The lens cap features a middle press structure design and is suitable for various lenses. The internal structure adopts a spring design to secure the lens cover to the lens, preventing external damage. 【Cleaning Cloth & Filter Case】 The cleaning cloth uses microfiber and has excellent absorbency, breathability, and cleaning power. It can thoroughly remove stubborn oil film and sebum stains. It will not damage the coating of lenses/filters and other optical equipment. The included lens filter case can be folded into three parts to store lens filters.
