變換口徑轉接環都是用於鏡頭(相機)改變口徑之用途,轉接環名稱中第一個起始口徑就是對應的鏡頭(相機)口徑。
轉接環口徑說明
以 RA xx yy 為例 xx M(公/外螺紋)-yy F(母/內螺紋)
前面 xx 數字為原始未轉前的口徑 ( 連接數位相機口徑 )
後面 yy 數字為外接後轉出的口徑( 外接鏡頭口徑 )
材質:金屬
M(公/外螺紋)螺紋在外側
F(母/內螺紋)螺紋在內側
此款式為反轉(逆轉)
使用的數位相機由於鏡頭大小問題而無法加裝各類濾鏡(例如:CPL、UV、MC UV、ND2、ND4、ND8、星光鏡、柔焦鏡、各種波長的紅外濾鏡等),所以也就出現了濾鏡轉接環。其作用為變換口徑,可以安裝到鏡頭前,達到不同口徑的鏡頭共用相同口徑的濾鏡、遮光罩、附加鏡頭等附件。或達到增加鏡頭口徑的目的。
