SIGMA 300-600mm f/4 DG OS Sports Sony E White camera lens

Sigma 300-600mm f/4 Sports Lens

The Sigma 300-600mm f/4 DG OS Sports is a constant-aperture ultra-telephoto zoom built for Sony E-mount cameras. It uses 28 elements in 21 groups, including six FLD and one SLD element, to control aberrations across the full range. The lens is finished in white with a magnesium alloy barrel and thermal insulation paint for demanding outdoor use.

Who this suits and who it does not

Wildlife, sports and aviation photographers who need to shift between 300mm and 600mm without changing lenses will benefit from the constant f/4 aperture and 5.5 stops of optical stabilisation at the long end. The High-response Linear Actuator drives fast, precise autofocus for erratic action. Buyers who need wider angles, lighter carry weight or a shorter minimum focus distance should look at other options.

Capacity and headroom

The 300-600mm range covers the majority of field-side and hide positions for large mammals, birds in flight and aircraft. At 600mm the 5.5-stop stabiliser gives usable handheld shutter speeds in moderate light, while the constant f/4 holds exposure steady through the zoom. Extremely low-light action or situations requiring focal lengths beyond 600mm will exceed the optical reach and aperture headroom this lens provides.
