Today I saw the ranking of polarizers, so let’s introduce the polarizers and the polarizers of Kengao.
polarization filter is a filter that provides bright colors and contrast by controlling reflected light. It can eliminate the reflection of surfaces such as water surface, glass surface, leaves and buildings, and make the blue sky bright, to highlight the original color of the subject. This filter is essential for landscape photography. The working principle of the
polarization filter is to adjust the reflected light by rotating the front box to make the colors bright. The polarization filter is a "polarization film" sandwiched between two pieces of glass. The "polarizing film" consists of many invisible slits that can cut off (absorb) light in a specific direction. The light source enters from all directions, but when it passes through the polarization filter, it becomes refracted in one direction.
Most polarization filters have triangle marks on the frames ▲. ▲ The reflection effect that marks change when they are on top is often maximized, but it changes according to the direction of the light. When using, please determine the rotation angle of the filter based on the effect on the viewfinder or LCD screen.
eliminates reflection on the water surface and leaves surface
The shooting effect is best when the plane is inclined at 30-40°.
No filter
Use polarization filter-eliminate surface reflection
No filter
Use polarization filter-eliminate glass
No filters
Use polarization filters - eliminate leaf reflections
to make the blue sky more bright and improve contrast
When shooting a blue sky, the position of the photographer should be directly below the sun, or behind them, and the sun is in the left and right directions, the effect is the most obvious.
filter is not used
polarization filter - the sky turns blue
Because the information says that the Kengao brand is the number one in polarizers, let's analyze it.
Kengao is a Japanese brand, and its mid-to-high-end products are still manufactured in Japan.
Kengao's unique high-definition polarization film
polarization film is the core of polarization filters and can be roughly divided into two types (high-definition polarization film and ordinary polarization film). After installing the filter, ordinary polarizers are usually reduced by 2 steps, while high-definition polarizers are only reduced by 0.5 steps. The advantage of
HD polarization film is that it has little impact on the shutter speed. It is almost no dimming when viewed through the camera's viewfinder, and it is also OK to hang the lens for a long time.
Normal polarizing films tend to have a slightly yellow color.
Waterproof and Oil-resistant Coating
Waterproof and Antifouling Coating is a coating that strongly repels water and oil. Even if dirt such as fingerprints are attached to the glass, it can be wiped off easily. Reduce the stress of shooting by the water or on rainy days.
Anti-reflection coating
When light reflects from the filter glass surface, glare and ghosting will occur. Anti-reflective coatings prevent unnecessary reflections and provide a clear image. The closer the percentage of surface reflection is to 0, the better the coating is. The surface reflectivity of ZX CPL and Celeste CPL is 0.3% or lower, which is the highest level of polarization filters on the market.
There is no anti-reflective coating and it is easy to occur
To sum up, the performance of the Ken high polarizer is roughly divided into the following series.
above are produced in Japan.
I am also convinced. There are so many series of polarizers, but each series is written very clearly without any ambiguity. Photographers can buy it according to their needs.
