Sigma 18-200mm f/3.5-6.3 DC Macro OS HSM Lens For Canon Digital Cameras

The Sigma 18-200mm f/3.5-6.3 DC Macro OS HSM Lens For Canon Digital Cameras is a versatile lens, covering an 11x zoom from wide-angle to telephoto. Its 35mm equivalent focal length range of 29-320mm makes the Sigma 18-200mm f/3.5-6.3 DC Macro OS HSM Lens For Canon Digital Cameras ideal for everyday shooting situations. The Sigma 18-200mm f/3.5-6.3 DC Macro OS HSM Lens For Canon Digital Cameras features a built-in optical stabilizer (OS) system, reducing the appearance of camera shake. This feature is helpful when shooting macro shots or long focal lengths. The OS is also practical for shooting in hand-held, low-light conditions, and the built-in Hyper Sonic Motor offers quick and quiet autofocus. 

The 18-200mm's optical design incorporates double-sided aspherical lenses which enable this extended super-zoom lens to be housed in a compact and lightweight construction. Special Low Dispersion (SLD) glass, correct chromatic aberrations, and Super Multi-Layer Coating reduces flare and ghosting, to provide sharp, high contrast images even in backlit conditions.

Macro Capability

With a minimum focusing distance of 15.4" (39 cm) and a magnification ratio of 1:3, the lens also acts as a macro lens. The maximum magnification for each focal length is indicated on the lens barrel. The product name on the front of the lens has been engraved, rather than painted, so that when shooting reflective objects up close, the letters will not show up in the image.

Thermally Stable Composite

TSC has the same level of thermal shrinkage as aluminum, with little elasticity, especially in temperature changes. This gives the lens high affinity to metal parts, and results in slimmer mechanical parts.

7 Blade-Rounded Diaphragm

The diaphragm creates aesthetically pleasing bokeh, or out of focus areas in images.

Brass Bayonet Mount

The bayonet mount on this lens is made from brass, which is highly accurate and durable, making this lens ideal for long-term use.

USB Dock

Compatible with the Sigma USB Dock, which can update the lens firmware and adjust parameters such as focus.
