According to relevant foreign media news, Hong Kong-based built-in filter manufacturer STC Optics announced that its built-in filter system will be available for Canon EOS R body models . This built-in filter is small in size and can be clamped directly in front of the sensor inside the camera body. It is reported that in addition to providing products with traditional ultraviolet filtering functions, the company has also introduced models designed to reduce light pollution for star photographers.
STC said that the built-in filter body has many advantages, especially for suppressing light spots and helping to keep the filter lens clean. It is also more convenient to use. Users do not need to worry about whether the lens fits their own device before purchasing. In fact, this lens is designed for the sensor size and is compatible with almost all interchangeable lens devices on the market.
