Sigma 18-250mm f/3.5-6.3 DC OS HSM Macro Lens for Sigma SA Mount

Sigma's 18-250mm F3.5-6.3 DC Macro OS HSM for Canon is a powerful wide-angle to telephoto lens specifically designed for Canon APS-C formats. This versatile zoom is an ideal choice for a many applications, making it a -go-to for photographers everywhere. With a focal length spanning from a wide-angle 18mm up to a 250 mm telephoto zoom, with macro capabilities to boot, Sigma's 18-250mm could easily be your camera's first all-in-one lens. At a relatively compact 4/0" long, its close minimum focusing distance of 13.8" makes this a great lens for macro photography. Their Thermally Stable Composite (TSC) construction maintains the structure of the lens, with little variation despite changing temperatures. The lens also incorporates a brass-made bayonet mount, to further reinforce the lenses durability and resistance to wear and tear over time. Sigma packed this lens with advanced features, including Sigma's exclusive Optical Stabilizer (OS) function. This provides approximately 4-stops of effective camera correction, allowing for lower-light shooting, or greater sharpness in adequate lighting situations. A Super Multi-Layer Coating has also been employed to reduce flare and ghosting with this lens. Three aspherical and one Super Low Dispersion element further ensure the optical performance of this lens, greatly reducing chromatic aberration and delivery rich color fidelity. It offers a 76.5° - 6.5° angle of view and accepts 62mm front-end filters. Optimization of the power arrangement by such as incorporating double-sided aspherical lenses, and reexamination of design, the filter diameter size is reduced. This compact size lens has the approximately 13x high zoom ratio with the filter size of diameter 62mm, and dimensions of diameter 73.5mm x Length 88.6mm. It ensures portability and overall ease of use, making it perfect for travel and leisure photography.

DC for Digital

These are special lenses designed for APS-C size sensors so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus!

Quiet and Fast Autofocusing

HSM lenses employ a motor powered by ultrasonic waves that produce a quiet, yet high-speed AutoFocus. You can enjoy high performance with low noise in a variety of shooting situations.

Optical Stabilizer

This function utilizes a built-in mechanism that compensates for camera shake. It dramatically expands photographic possibilities by alleviating cameras movement when shooting by hand held camera.

Superior Optical Performance

SLD (Special Low Dispersion) glass element offers excellent correction of color aberration. Three aspherical lenses including double-sided aspherical lens together with the latest design, prevent and correct all types of aberrations including astigmatism, achieving high quality images throughout the entire zoom range.

Flare and Ghosting Reduction

From an early stage, flare and ghosting are thoroughly measured to establish the design which is resistant to strong incident light such as backlight. Super Multi-Layer Coating reduces flare and ghosting, and provides sharp and high contrast images even in backlit conditions. Supplied petal-type hood can be attached to block out extraneous light which has a harmful influence on rendering of the lens, and prevent internal reflections to occur.
