Sigma 50-120mm f/2.8 DC OS Contemporary for Canon RF

The Sigma 50-120mm f2.8 DC OS Contemporary Lens is a constant-aperture APS-C telephoto zoom covering approximately 75-180mm in 35mm equivalent, completing Sigma’s compact f2.8 APS-C zoom range alongside the 10-18mm and 18-50mm Contemporary lenses. Its compact body combines an f2.8 aperture with HLA autofocus and OS2 optical stabilisation up to 6.5 stops, giving photographers a relatively small telephoto setup for portraits, events and tighter compositions. Close focusing adds further flexibility, while suppressed focus breathing keeps framing more consistent when recording video.
