H&Y Filters K-Series ND 濾鏡 (Drop-In)

來自H＆Y濾鏡的此Drop-In K系列ND 3.0濾鏡是ND濾鏡，其濾鏡係數為1000倍，可減少10級曝光。它安裝在鋁合金過濾器環中，專門安裝在可單獨購買的H＆Y過濾器100mm K系列過濾器支架與過濾器支架的轉接環之一之間。濾鏡的3.0密度會使整個圖像變暗，從而使您可以以比通常所需的更大的光圈或更慢的快門速度進行拍攝。通過減慢曝光時間或增大光圈，您可以控制景深並更輕鬆地傳達運動。中性密度濾鏡不會影響圖像的色彩，是與其他濾鏡配對的理想選擇。

插入式K系列中性密度3.0濾鏡由SCHOTT B270玻璃製成，可提高光學清晰度和色彩保真度。該濾鏡的每一面都包括八層防反射塗層，以防止內部重影和反射；以及防污納米塗層，當與水或油接觸時可改善成串效果，從而提高清潔效率。
