The Sigma 18-200mm f/3.5-6.3 DC HSM OS Lens is the second addition to the Contemporary line from Sigma's Global Vision. The Sigma 18-200mm lens was designed for APS-C sensors and features a new matte black finish, thermally stable composite material in its construction and smaller and lighter design then previous models. With exceptional performance, this 18-200mm camera lens does not sacrifice image quality for versatility. Having the ability to shoot from wide angle to telephoto is highly useful particularly for travel photography, landscape photography, street photography, portrait photography and nature photography.
An improved minimum focusing distance of 14.7 inches paired with the use of Special Low Dispersion glass, the 18-200mm excels at bringing out great detail in close-up photography as well. A Hyper Sonic Motor (HSM) ensures quiet, accurate and fast autofocus and an optical Stabilizer (OS) helps compensate for camera shake. Make this lens your all-in-one lens to handle any shooting scenario.

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. This 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 18-200mm F3.5-6.3 DC 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, this new 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.
Diameter reduced by 4.6mm compared to its predecessor
Sigma pursued a compact size as an ideal everyday lens. From an early stage of development, SIGMA was determined to make the lens size compact, for example, by incorporating double-sided aspherical lens elements and downsizing the motor. As a result, while the predecessor had a diameter of f75.3mm, this lens has reduced it to f70.7mm, which has the difference of 4.6mm. It also achieves -11% in volume ratio compared to its predecessor. It is one of the smallest in its class of lenses with more than a 7x zoom ratio, and is more comparable in size to a generic standard zoom lenses.
High rendering performance throughout the entire zoom range
With our Contemporary line, the 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.
One of the biggest features of this lens is that it is possible to shoot subjects as close as Macro lenses. This lens features a minimum focusing distance of 39cm and a maximum magnification ratio of 1:3. It offers the versatility for shooting close-ups of fashion accessories, cuisine, flower arrangements and much more without changing the lens. Its working distance is 14.7cm, and it is suitable for shooing images with natural light as it keeps the shadows of camera and lens off of the image. On its lens barrel, it indicates the maximum shooting magnification at each focal length, and it is so convenient for a photographer that the size of the object in the image sensor becomes easily recognizable. Uncompromising in every aspect of lens design, Sigma has even chosen to engrave the product name on the front of the lens to prevent reflections of the letters during close-up 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. This 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.
Incorporating Rounded Diaphragm
The 7 blade-rounded diaphragm creates an attractive blur to the out-of-focus areas of the image.
Hyper Sonic Motor
HSM (Hyper Sonic Motor) delivers high AF speed and extremely quiet performance. With the latest AF algorithm, smoother AF is achieved.
Brass made bayonet mount
This lens incorporates a brass made bayonet mount which has both high accuracy and durability. A special treatment to reinforce its strength is applied to the surface giving it greater strength and making it highly resistant to long-term use.
Ease of use
The new product lines incorporate rubber for the attachment part of the provided lens hood. For better usability, the design of the lens cap and AF / MF changeover switch has been improved.
