Micro Four Thirds is a camera system that uses a sensor size of 17.3 x 13.0 mm, which is smaller than traditional DSLR sensors. This format allows for more compact and lightweight camera bodies and lenses, making it popular among photographers who prioritize portability without sacrificing image quality. The Micro Four Thirds standard was developed by Olympus and Panasonic in 2008, promoting interchangeable lenses and a shared mount system. This compatibility enables users to choose from a wide range of lenses, enhancing creative possibilities while maintaining a smaller overall system size.
