The Sigma APO 70-200mm F2.8 EX DG OS HSM is highlighted as a budget-friendly, professional alternative to higher-priced stabilized f/2.8 telezoom lenses from Canon, Nikon, and Sony. Evaluated using a 36-megapixel Nikon D810, the lens delivers impressive center sharpness across most of its focal range, significantly exceeding sharpness standards at 70mm, 100mm, and 140mm when stopped down. Key advantages of this 3.2-pound lens include its fixed f/2.8 aperture, built-in optical image stabilization with two distinct panning modes, and the inclusion of a hood and tripod collar. However, because it is an older model, it lacks eligibility for Sigma's mount conversion service. Despite its solid value, the lens compromises on edge performance and exhibits noticeable optical distortion. Testing revealed a strong 2.4% barrel distortion at 70mm alongside weak peripheral sharpness, though stopping down to f/5.6 or f/8 helps correct these edge issues. The lens's greatest weakness occurs at the 200mm maximum focal length, where image sharpness drops off drastically at f/2.8, requiring shooters to close the aperture to f/8 or f/11 to achieve optimal, crisp results. Ultimately, while it falls short...

The Sigma 70-200mm f/2.8 EX DG OS HSM APO lens delivers a strong performance, especially when paired with the 16-megapixel Foveon sensor of the Sigma SD1 Merrill camera, which yields higher resolution results than competing Bayer-sensor cameras like the Canon 60D or 5D Mark II. Built with a solid, durable finish, the lens features smooth zoom and focus rings and a highly practical tripod socket that can be quickly removed without detaching the lens from the camera body. Optically, the lens excels by offering exceptionally low vignetting even wide open, minimal distortion across its zoom range, low chromatic aberration, and a smooth, attractive background bokeh. The major advantages of this lens include its very high center resolution starting at f/2.8 (except at 200mm), lightweight design compared to Canon and Nikon alternatives, and its highly attractive price-to-quality ratio. Additionally, it comes well-equipped with a durable pouch and two separate lens hoods for APS-C and full-frame sensors. However, the review highlights notable downsides: the autofocus system is not particularly fast and tends to hunt in low light or low contrast environments when...

The DPReview evaluation of the Sigma 70-200mm f/2.8 OS highlights a well-built design featuring a uniquely designed, detachable hinged tripod ring and a versatile three-position Optical Stabilizer (OS) switch. Handling is further enhanced by specialized switches, allowing for precise control over image stabilization during both static and panning shots. DPReview Conversely, the review notes significant drawbacks, including the omission of a focus limiter switch, which can lead to increased lens hunting in action photography. Additionally, the lens lacks environmental sealing at the mount, and the zoom ring becomes inaccessible when the lens hood is reversed for storage.

The Sigma 70-200mm f/2.8 EX DG OS HSM is a highly recommended, budget-friendly telephoto zoom lens that offers excellent value compared to its more expensive first-party competitors. Tested on a high-resolution 36MP full-frame sensor, it delivers strong, reliable contrast and sharpness in the image center across the entire focal range, even when shot wide open at f/2.8. Key advantages include built-in Optical Stabilization (OS), a constant fast f/2.8 aperture, an internal focusing mechanism that preserves lens length, and a standard 77mm filter thread. Additionally, its center resolving power remains high enough to successfully pair with a teleconverter for an extended reach. However, the lens exhibits clear performance trade-offs, particularly at longer focal lengths and near the outer edges of full-frame sensors. The 200mm focal length proves to be its weakest end, where the image corners suffer heavily from astigmatism, spherical aberration haloing, and visible vignetting. Photographers must stop down significantly to f/8 or f/11 to achieve sharp, uniform cross-frame resolution. Other notable disadvantages include a lack of weather-resistant sealing at the mount, a bulky profile weighing over 1.4kg, and a...
