Use a Lineup of Different Lenses

The open design standard of Micro Four Thirds combines interchangeable lenses and camera systems from different brands without limiting someone to using a range of lenses and cameras from one company.

Compact, Lightweight, and Excellent Image Quality

The ability of this device to provide sharp image quality at a compact size is a result of the optimal relationship between the mount and the image sensor size.

Origins of the Micro Four Thirds Sensor

In 2008, Panasonic and Olympus agreed to build a digital camera and fit it with a standard lens mount that would allow both companies to attach a wide variety of lenses to the same mount. This setup allows any Micro Four Thirds owner to use the lens collection from the two competing companies on the same camera.

The Role of the Digital Camera Sensor Size

A Micro Four Thirds has a compact sensor that is a quarter of the size of a full-frame camera sensor. Therefore, if you want to get quality images with an easy-to-carry small sensor camera, the M4/3 is a good fit. You may also want to find out what is FPS in a digital camera, as well as digital camera speed, ISO performance, and aspect ratio in a digital camera before you invest in one.
