To capture images, D-SLR cameras incorporate a device called an image sensor (CCD, MOS, etc.) that captures light in the form of electrical signals.
However, since the image sensor’s characteristics differ from those of film, a lens optimized for film photography may perform poorly with an image sensor.
The Four Thirds Standard is the answer to the uncompromising demands of professional photography. It represents a break from the past and frees digital SLR photography from the confines of conventional camera technology. Since its introduction in 2002, this trend-setting standard has received worldwide recognition for its superior performance and enhanced compatibility.
The core design concept of the Four Thirds Standard is to facilitate optimization of the size, performance, and extendibility of digital cameras and lenses. In addition, a standardised lens mount allows photographers to freely combine interchangeable lenses and cameras from different manufacturers. This is the key feature of the Four Thirds Standard, the one that makes it possible to explore the full potential of digital photography.
