호야 HD CPL 필터에 디어서

해외직구 대행으로 하나 질렀습니다.

네트 가격은 USD 90

B+W 브랜드의 37미리 동일 사이즈 CPL중에선 더 윗 모델이 없더군요.

렌즈 구경이 작으니 상대적으로 가격이 저렴해서 만만합니다.

<< B+W 37mm Kaesemann High Transmission Circular Polarizer MRC-Nano Filter >>

사고 싶은 건 헬리오판인데... 가격이 만만한 건 B+W이네요.

PZ X14-42렌즈에 달아줄 건데... 렌즈 중고시세나 필터시세나

거의 대등하군요.

포서드에 대형렌즈는 의미가 없다고 생각해서 가급적 작은렌즈로

버텨볼까 합니다.

개인적인 생각엔 순정 X렌즈도 충분히 굴릴만 하다고 생각합니다.

풀프레임 바디와 대포렌즈에 장착되는 77미리/82미리 ~ 95미리 필터류 가격에 비하면

37미리 필터는 정말 저렴하네요.

The B+W 37mm Kaesemann High Transmission Circular Polarizer MRC-Nano Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

Kaesemann High Transmission Circular (HTC) polarizing filters are fitted with polarizing foils which provide 99.5% light transmission that are cemented between plano-parallel optical glass. The resulting sandwich is then precision-polished to achieve accurate plano-parallel surfaces. Finally, they are edge-sealed to protect the foil against humidity.

To prevent internal ghosting and reflections, each glass surface includes multiple layers of anti-reflection coating. This Multi-Resistant Coating (MRC) also offers further protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. The Nano coating associated with XS-Pro filters provides an additional eighth layer over the MRC, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

B+W filters are constructed from Schott glass for increased optical clarity and color fidelity. This filter features a thin brass filter ring to minimize the potential for vignetting while enhancing durability and jamming prevention. To further reduce the possibility of vignetting when this filter is in use, the filter ring's outside diameter is slightly larger than the actual thread size. This may prevent the use of some lens manufacturer bayonet hoods.

Clears up haze in distant landscapes and provides more saturated, vivid colors.

Strongest effect when used at a 90° angle from the sun.

Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.

Multicoated to prevent internal ghosting and reflections while providing over 99.5% light transmission.

2 to 2.8x filter factor reduces exposure by 1 to 1.5 stops.

Constructed from Schott glass for optical clarity.

Nano coating provides an improved beading effect with water for more efficient cleaning.

Plastic filter case for storage and transport.
