Four Thirds is a standard for digital camera sensor size, measuring approximately 17.3mm by 13mm. It is commonly used in mirrorless interchangeable lens cameras, offering a balance between image quality and compactness. Four Thirds sensors are smaller than APS-C sensors but larger than those found in point-and-shoot cameras. This sensor size allows for high-quality images with lower noise levels and better low-light performance. Cameras utilizing the Four Thirds standard often feature a smaller form factor and lighter weight, making them ideal for travel and everyday photography. Overall, Four Thirds cameras offer a versatile option for photographers seeking a portable yet capable setup.
