Sigma 150-600mm F/5-6.3 DG DN OS | S

The Sigma 150–600mm F/5–6.3 DG DN OS Sports is a telephoto zoom for full-frame mirrorless cameras, introduced in 2021. Separate versions fit L-Mount and Sony E bodies. Choose the version for your camera.

Its range suits wildlife and outdoor sport where subjects keep their distance. At shorter settings you can include a larger animal or more of a scene. Full reach isolates distant details. The main trade-offs are a heavy body and a modest maximum aperture for dim conditions.

Both versions weigh 4 lb 10.1 oz (2100 g) including the tripod socket. The L-Mount version is 10.38 in (263.6 mm) long and 4.31 in (109.4 mm) across; Sony E is slightly longer. This is substantial equipment to carry, and a monopod or tripod can support it during long sessions.

Screw-in filters must match the 95mm thread on this lens.

At 600mm, a distant bird or player fills more of the frame. Zooming back toward 150mm gives room when the action approaches or changes direction. You can first find a moving subject at a shorter setting, then tighten the framing. This helps when your own position is fixed.

The maximum aperture changes from f/5 at 150mm to f/6.3 at 600mm. In dawn shade or heavy cloud, maintaining a fast shutter speed may require a higher ISO. Still subjects give you more room to use a slower exposure, especially with firm support.

At close subject distances, the long settings can soften a distant background even at f/6.3. The distances matter: reeds directly behind a bird can stay distracting, while trees far beyond it are easier to blur. Change position when you can to find a cleaner backdrop.

Closest focus is 1.9 ft (58 cm) at 150mm, measured from the sensor. The minimum distance increases toward the long end. Maximum magnification is 0.34x at 180mm, a separate setting. Leave space ahead of the glass and avoid disturbing small animals while framing nearby details.

Optical stabilization provides four stops of camera-shake correction at 600mm on a full-frame camera under CIPA conditions. It helps steady handheld framing and still subjects. A moving bird still needs enough shutter speed for its movement.

The zoom switch locks at 150mm. A tighter setting adds resistance to help hold other focal lengths while carrying the lens. Dust and splash resistance help outdoors, while the water- and oil-repellent front coating eases cleaning. Use cover in persistent rain.

On L-Mount, compatible Sigma teleconverters can extend reach, at the cost of light.

The design uses 25 elements in 15 groups. Four FLD and two SLD elements help reduce chromatic aberration, which occurs when colours focus at different points. It can leave fringes along high-contrast edges, such as a dark bird against a bright sky.

The L-Mount version uses internal focusing, which keeps the barrel length fixed as focus changes.
