Friendly reminder:
●The aperture of the filter depends on the aperture of your lens, and has nothing to do with the camera model! Please choose the correct filter for your lens!
●Before purchasing a filter, please make sure to purchase the size of the lens. The lens cover or the front of the lens are generally marked (for example, Φ67 means 67mm or directly marked 67mm)
PolarizerIt consists of two pieces of optical glass sandwiched by a tiny polarizing crystal with directional effect.(Like mica)Composition, the polarized reflected light on the surface of the object can be eliminated by rotating the lens.
According to different mechanisms of filtering polarized light, polarizers can be divided into circular polarizers(Abbreviated as CPL)And linear polarizer(Abbreviated as LPL)Two, the functions of the two are the same. LPL is mainly used in old manual focus cameras.
Many things reflect light: the sky, the ground, the water surface, glass, smooth tabletops, including flowers, trees, and human skin, etc., relatively smooth surfaces will reflect light. Do I need to use a polarizer when shooting these objects? In theory, this is the case, especially when shooting objects below the water surface or in a glass window, a polarizer is essential. For indoor lighting, polarizers can also achieve the same effect. The use of polarizers can eliminate the reflective characteristics of non-metal surfaces such as wooden tables, filter the light reflected by the desktop, but have no effect on the reflection of the metal, which can prevent the reflection of the desktop from affecting the subject, and show the texture of the metal utensils.
When shooting under strong sunlight, the sky, the ground, especially the asphalt pavement can easily reflect sunlight, so it is best to add a polarizer for shooting.
Polarized lenses are also useful when shooting on cloudy days. Because the cloudy sky can be regarded as a huge light source, the smooth surface of the object will reflect the light of the sky.

Note: When using a polarizer, it is inconvenient to use the hood due to the need to rotate the filter, so you should try to keep the camera in the shadow to shoot; after installing the polarizer, the amount of light through the lens will be reduced, auto mode, aperture priority and shutter priority In the mode, the camera will make adjustments by itself, but if it is manual exposure, you must pay attention to adjust the exposure compensation appropriately. From this point of view, the polarizer can also be used as a dimming mirror when it is necessary. Approximately the effect of ND4.
Polarizer PL and reflective surface(Glass window or water surface)Use at an angle of 30-40 degrees can achieve the greatest effect in eliminating reflections, and at an angle of 90 degrees(Straight to the reflective surface)Little or no effect of use.
In order to increase the color density of the blue sky, when the sun is at an angle of 30-40 degrees in the sky and the camera is directly at the sun, the PL polarizer obtains the maximum effect. At noon, the sun is above the head or at a 90-degree angle to the ground. At this time, the effect of the polarizer is the least. These effects can be easily seen in the viewfinder of the camera. Simply turn the polarizer to check the effect
