Linear polarizers are commonly used in photography to reduce glare and reflections from surfaces such as water, glass, and foliage. However, when it comes to mirrorless cameras, there are certain considerations that need to be taken into account.
Mirrorless cameras differ from traditional DSLRs in that they lack a mirror to reflect light into an optical viewfinder. Instead, they use an electronic viewfinder or LCD screen to display the image. This means that the light entering the camera is already linearly polarized by default. Using a linear polarizer can result in incorrect exposure and possible loss of image quality.
However, this doesn’t mean that polarizers are completely useless on mirrorless cameras. Some photographers may still find them beneficial in certain situations. For example, if you’re shooting landscapes and want to enhance the color and contrast of the sky or reduce glare from water, a circular polarizer is a better option.
A circular polarizer consists of a linear polarizer combined with a quarter-wave plate, which converts the linearly polarized light into circularly polarized light. This allows the camera’s autofocus and metering systems to function properly, while still providing the desired polarizing effect.
In conclusion, while linear polarizers may not be suitable for use on mirrorless cameras, circular polarizers can still be used to achieve the desired results without compromising image quality or camera functionality.

What is a linear polarizer?
A linear polarizer is an optical filter that works by selectively filtering out light waves that are oscillating in a specific direction. It consists of a special film that is coated with a microscopic pattern of lines. These lines act as a barrier, allowing only light waves that are oscillating in a specific plane to pass through.
How does it work?
When unpolarized light passes through a linear polarizer, the filter blocks out all light waves that are not aligned with its transmission axis. This causes the light waves to become polarized, meaning that they vibrate in only one plane. The filter acts as a barrier to light waves that are oscillating perpendicular to its transmission axis, effectively reducing the brightness of the light and eliminating glare.
Applications
The use of a linear polarizer can have various applications. In photography, it can be used to reduce reflections and glare from non-metallic surfaces such as water or glass, resulting in more vibrant and saturated colors. It can also enhance the contrast between the sky and clouds, making the clouds appear more dramatic against a blue sky.
Furthermore, linear polarizers are used in other fields such as microscopy, LCD displays, and optical communication to control the polarization of light waves and improve image quality or transmission efficiency.
Note: Linear polarizers have certain limitations and may not be suitable for all situations. For example, they can interfere with the autofocus systems of some cameras, particularly mirrorless cameras. It is important to check the compatibility and potential issues before using a linear polarizer on a mirrorless camera.
