UnverifiedND档位选择遵循快门=帧率2倍原则：24/25fps拍视频，晴天需ND16-ND32，多云ND8，阴天ND4；仅拍照不需要ND滤镜85% similarUnverifiedND滤镜减光档位选择：ND8(3档)适合阴天流水，ND64(6档)适合白天瀑布慢门1秒左右，ND1000(10档)才能实现白天数十秒长曝拍云海车流76% similarUnverified可调ND在接近最大挡位（ND400附近）时普遍存在X形暗角，此产品同样无法避免，广角端尤为明显，不建议用于广角镜头的强减光场景75% similarUnverified跟焦需求为主时优先选对焦行程≥270度且线性（非速度渐变）的镜头，长行程带来更精细的跟焦分辨率；单人无跟焦器拍摄反而适合行程较短的镜头（如135度）以便快速手动对焦73% similarUnverified变色镜片响应速度有限，从明到暗切换需10-30秒，隧道频繁进出或树荫斑驳路段体验差，此类场景不如固定浅色镜片72% similar
