K&F CONCEPT 77mm Variable ND Filter ND2-ND32 + CPL Filter 2-in-1 Lens Filter, No X-Shaped Artifacts, Made in Japan AGC Optical Glass, HD Ultra-High Resolution, Low Reflectance, 28-Layer Nano Coating, Water and Oil Repellent, Scratch Resistant, Video/Landscape Photography, Light Reduction, Polarization I've also attached photos, but I purchased this from the manufacturer's official Amazon store in January 2020. I haven't had a chance to use it since I bought it due to the COVID-19 pandemic, and although I don't have the box, it's a new, unused item. I've decided to sell it because I've also gotten rid of my full-frame camera. 【CPL & Variable ND Filter】77mm CPL + Variable ND, a 2-in-1 lens filter. Compatible with 77mm lenses, please check your lens size beforehand. If you want to attach a lens cap (lens cover), you'll need a lens cap that's two sizes larger (86mm). *The exterior packaging may be a mix of old and new, but the contents are the same. 【No X-Shaped Artifacts】The variable ND filter with X-shaped artifact prevention has a light amount lock function. After adjusting the level by rotating from minimum ND2 to maximum ND32, the automatic lock function fixes the position of the glass to avoid the angle where the filter causes unevenness, preventing X-shaped artifacts. 【Green Film & Anti-Reflection】The C-PL filter uses green film to cut ultraviolet rays while removing environmental polarization, making the sky bluer, and controlling the light reflected on the water surface to make the scenery clearer. You can also express the underwater scenery seen through the water surface, the scenery reflected on the water surface, and the transparency of wet leaves. 【ND2-ND32 Variable Light Reduction & Polarization】Adjustable from ND2 to ND32, in 5 steps (stops). While using the circular polarizing PL filter for various expressions, you can use slow shutter speeds to smooth the flow of clouds and waterfalls, and express the light trails of lights. 【Water and Stain Repellent】The filter surface is processed with 18 layers of nano-coating, achieving water and oil repellency. You can shoot with confidence even in harsh environments such as rivers, mountains, and deserts. High-quality reinforced optical glass is used to significantly reduce lens flare and ghosting, suppress reflections, and freely take bright and colorful photos.
