B+W濾鏡的種類編號
這邊來了解一下,B+W濾鏡選購時,一些型號上的辨別。
型號的差異
型號 | 功能 |
PRO-UV | 單層鍍膜UV |
PRO-MRC-UV | 多層鍍膜UV |
MRC-XS-PRO-UV | 超薄多層鍍膜UV |
MRC-Nano-XS-PRO-UV | 奈米超薄多層鍍膜UV |
IR-CUT-MRC-486-UV | 486紅外線多層鍍膜UV |
VIP-DMRC-UV | 金圈多層鍍膜UV |
SIL-MRC-UV | 銀圈多層鍍膜UV |
但目前B+W的Schneider-Kreuznach已經推出了新的產品線Master與Basic。
Master取代的是XS-Pro,Basic取代的是F-Pro。Master全系列都採用MRC Nano的鍍膜封蓋技術,
光線對不同封裝鍍膜的影響
(左:E 單層鍍膜)Light incidence on an uncoated filter: about 4% is reflected
(中:MRC 多層鍍膜)From the surface of a B+W E coated filter, roughly 2% of the incident light is reflected
(右:MRC nano 奈米高硬度多層鍍膜)From the surface of a B+W MRC nano coated filter, roughly 0.5% of the incident light is reflected
水滴對不同封裝鍍膜的影響
(左:E 單層鍍膜)In an uncoated filter the water droplet remains flat. A dirt and water-repellent effect does not occur.
(中:MRC 多層鍍膜)In the MRC coated B+W filter, the water droplet takes on a rounded shape. It beads away from the surface. A dirt and water-repellent effect occurs.
(右:MRC nano 奈米高硬度多層鍍膜)In the MRC nano coated B+W filter, a water droplet remains practically spherical. It rolls over the surface. A first-rate dirt and water-repellent effect occurs.
如何從型號判別有無UV濾鏡功能
007|clear 無UV濾鏡(純保護鏡功能)
010|有UV濾鏡
