The Sigma 60-600mm f/4.5-6.3 DG lens is a super-telephoto zoom lens produced by Sigma Corporation since 2018. It succeeds an earlier 10× zoom lens (50–500mm) which was introduced by Sigma in 2000 and is commonly known as the "Bigma". It is aimed at advanced consumers. The 60–600mm lens is produced in two versions: one exclusively for single lens reflex cameras, with Canon EF mount, Nikon F mount, and Sigma SA mount versions, named the 60–600mm F4.5-6.3 DG OS HSM | S, and one exclusively for mirrorless cameras, in Leica L-Mount and Sony E-mount versions, named the 60–600mm F4.5-6.3 DG DN OS | S.
