Contemporary line that covers a wide range of photography

SIGMA is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. Among the three, the Contemporary line is a high performance line which incorporates the very latest technology making it possible to accommodate both high optical performance and compactness for use in various photography situations. Sigma has solved the difficult problem of keeping the size and weight down without compromising optical performance and function with the latest technology. The Sigma 18-200mm f3.5-6.3 DC Macro HSM Lens covers frequently used wide-angle to telephoto, as well as macro photography.

New standard zoom up to 200mm

Sigma has always been producing a high performance standard zoom lens, dedicated for digital DSLR cameras, that covers up to 200mm by reflecting the latest technology. In 2005, Sigma released the Sigma 18-200mm f3.5-6.3 DC Macro HSM Lens as a smallest and lightest all-rounder lens in class that covers from wide-angle to telephoto range. Sigma, in 2007, incorporated OS (Optical Stabilisation) functionality, and in 2011, has successfully made the size of the lens even more compact. Now, the Sigma 18-200mm f3.5-6.3 DC Macro HSM Lens has been redeveloped as the standard zoom lens from Sigma’s new product line, which has higher performance, is even smaller and lighter-weight, and on top of that, includes “the macro feature”. As an entry level interchangeable lens, it is capable of many photographic scenes.

High rendering performance throughout the entire zoom range

With our Contemporary line, the Sigma 18-200mm f3.5-6.3 DC Macro HSM Lens is required to fulfill the maximum potential while achieving a compact and light-weight construction. This lens incorporates SLD (Special Low Dispersion) glass elements that have a high refractive index, and corrects chromatic aberration at the telephoto-end very well. Moreover, aspherical lens elements, including double-sided aspherical lenses, ensure a compact size and excellent correction of distortion. This also helps to produce superior rendering performance throughout the entire zoom range from wide-angle to telephoto and macro photography.

Incorporating new composite TSC

In product development of cameras and lenses, it is crucial to lay out main components, metal parts and polycarbonate, to optimise and ensure each feature. ThSigma 18-200mm f3.5-6.3 DC Macro HSM Lens has incorporated TSC (Thermally Stable Composite) that has the same level of thermal shrinkage as aluminium and little elasticity, especially in temperature changes. Since thermal shrinkage is low, it has a high affinity to metal parts that contributes to high precision in product manufacturing. It also results in slimmer mechanical parts, such as the zoom ring and scaling.

Designed to minimise flare and ghosting

Flare and ghosting were thoroughly measured and monitored from the lens development stage to establish an optical design which is resistant to strong incidental light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions. Attaching the matched petal type hood, which is supplied, will provide extra protection from flare and ghosting.
