Fotografie

A compact digital camera format designed around a 17.3 x 13mm imaging sensor, which is a quarter the size of a full-frame (35mm) imaging sensor. Four Thirds cameras and lenses are manufactured primarily by Olympus and Panasonic. Lenses are made by several manufacturers. A variation of Four Thirds is Micro Four Thirds, a mirrorless Four Thirds camera format, which is even smaller than standard Four Thirds format cameras. The sensors in Four Thirds and Micro Four Thirds are identical, but Micro Four Thirds optics cannot be used on standard Four Thirds camera bodies, due to their smaller lens mounts.

Four thirds

Standard lansat de Olympus si Kodak pentru D-SLR, construit in jurul unui senzor in format 4/3 inch (18 × 13,5 mm si diagonala de 22,5 mm). Corpul camerei este mai mic si mai usor iar obiectivele au o constructie speciala (telecentrica, pentru a reduce vignetarea) si distanta lor de focalizeaza este echivalenta 135 cat dublul valorii inscriptionate. Comunicarea intre obiectiv si camera se realizeaza prin 9 contacte (standard) astfel incat pot fi utilizate obiective ale unui producator, pe corpul realizat de alt producator. .
