Sigma 24-70mm f/2.8 DG DN II Art vs Sony FE 24-70mm f/2.8 GM II

Both are constant f/2.8 standard zooms for Sony E-mount, and both are excellent. The Sony GM II is the lighter, smaller lens with faster and quieter autofocus, four XD linear motors, and a closer minimum focus distance, so it suits video shooters and anyone who carries one lens all day. The Sigma Art II is a strong alternative with an aperture ring, a similar optical formula, and a reputation for sharpness wide open at a lower cost of entry. Owners of both praise sharpness and build; the Sony edges ahead on focus speed and size, the Sigma on the aperture ring and value.

• Choose the Sigma 24-70mm f/2.8 DG DN II Art if you want an aperture ring, a slightly more affordable way into a fast standard zoom, and sharpness wide open that holds up to the G Master.
• Choose the Sony FE 24-70mm f/2.8 GM II if you shoot video or fast action and want the lightest, smallest body, the fastest autofocus, and the closest focusing of the two.
