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-UV486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
