When using a digital camera, sensor dirt is inevitable. This is especially true for mirrorless cameras, where dust can easily enter during lens changes, leading to time-consuming and costly cleaning.
The 'clip-in filter,' which is installed inside the camera, is gaining attention as a solution to this problem.
Placed directly in front of the sensor, this small filter reduces the need for frequent cleaning and is transforming the camera experience.

Why Manufacturers Don't Recommend It
Clip-in filters are produced by third-party brands like Kolari Vision and Kase, and they are compatible with a wide range of models, including Sony, Nikon, Canon, Fujifilm, and Leica.

Manufacturers do not recommend their use, citing the potential for 'image quality degradation.' However, in reality, high-quality filters made with optical glass show minimal noticeable degradation, which is why many creators are adopting them.
How to Use and Benefits
The usage is simple: turn off the camera, clean the sensor with a blower, and attach the filter magnetically inside the mount. Once installed, it does not affect autofocus or operability and protects the sensor from dust and debris during lens changes.
It is particularly effective for older models without sensor shields, significantly reducing cleaning frequency and service costs.
