关于该商品 about this item
This filter uses our standard B+W F-Pro filter mount, which has a front accessory thread and is made of brass.
Each glass surface is vacuum coated with one layer of Anti-Reflection coating. This single layer helps to prevent internal ghosting and reflections. It also improves light transmission from approximately 92% (uncoated glass) to over 98%.
Manufactured from Water-White Schott Glass

Highly efficient standard circular polarizing filter for all cameras with beam splitters in the light paths of their TTL exposure meter and with autofocus lenses. Circular polarization has the same pictorial effect as linear polarization, but allows for proper exposure metering and/or autofocus distance settings. B+W Polarizers increase color saturation and reduce reflections. High-quality optical glass ensures excellent pictorial quality. The filter factor varies according to how the filter is positioned in relation to the sun. Filter factor is between 2.3 and 2.8.
对于所有相机的高效标准圆形偏振滤波器，其TTL暴露仪表的光路和自动对焦镜片中的光路。圆极化具有与线性极化相同的图像效果，但允许适当的曝光计量和/或自动对焦距离设置。 B + W偏振器增加色彩饱和度并减少反射。中性灰色和平面平行偏振器材料保证最佳图像结果。高品质的光学玻璃可确保优异的图形质量。过滤器因子根据过滤器与太阳相关的方式而变化。过滤器因子在2.3和2.8之间。
