Overview: The Sigma APO 70-200mm F2.8 EX DG OS (Model #589) is a
high quality telephoto zoom lens. Typical uses include travel, weddings &
events, portraits, nature & wildlife, and sports & action photography. The
lens has the Canon EF-mount, and comes with a tripod collar, lens hood, and front and rear caps.
Sigma DG Lenses: This Sigma DG lens is designed for use with
full-frame digital SLRs, but can be used with DSLRs with APC-C-sized image
sensors. DG lenses offer high contrast and subtle tonal gradations, but is
resistant to flare and ghosting. The lens' Super Multi-Layer Coating suppresses
reflections between the image sensor and the lens surfaces.
Optics: The lens features two FLD glass elements, which have
the performance equal to fluorite glass, and three SLD glass elements. Both
types of glass elements provide excellent correction of color aberrations.
Lens Hood: The lens includes a bayonet-type
detachable lens hood to help
prevent stray light from entering the lens, causing flare, and to protect the
lens from rain, snow, and dust. When not in use, the lens hood can be inverted
and mounted onto the lens backwards for storage. The lens hood adds
approximately 4" to the overall length when mounted. When using the lens
hood with cameras with APS-C sensors, it is recommended that you add the lens
hood adapter for more effective shading.
Optical Stabilizer (OS): The built-in Optical Stabilizer
allows for handheld photography, even in low light scenarios, and compensates
for image blurring caused by camera shake. There are 2 OS modes: Mode 1
compensates for overall camera shake, while Mode 2 detects vertical shake that
occurs when panning the camera horizontally.
Teleconverters: The lens can be used with Sigma's 1.4x EX DG
or 2.0 EX DG APO teleconverters. This converts the 70-200mm lens to a 98-280mm
F4 or 140-400mm F5.6 lens, respectively.
Tripod Collar: Because of the weight of the lens, a tripod
collar is included which lets you mount the lens onto a tripod. This provides
better balance and stability when shooting for long periods of time. You can
rotate the lens inside the tripod ring to allow you to shoot images in portrait
orientation with the lens attached to the tripod.
Focus Mode Switch: The lens features a two-way switch for
setting the focus mode: AF (auto focus) or M (manual focus).
HSM: The lens has a hyper-sonic motor (HSM) that provides a
quiet, high-speed auto focusing mechanism.
