Sigma 17-70mm F2.8-4 CONTEMPORARY DC Macro OS HSM (Pentax) - SM884109
Product Overview
The 17-70mm F2.8-4 DC Macro HSM OS is the first lens in the Contemporary line of Sigma’s Global Vision. The Sigma 17-70mm F2.8-4 was designed to be the ideal all-purpose lens for APS-C DSLRs. With a versatile focal length and macro capability, the 17-70mm F2.8-4 is also equipped with a Hyper Sonic Motor (HSM) and an Optical Stabilizer (OS) for superior image quality. The HSM ensures quiet, accurate, and fast autofocusing while the OS compensates for camera shake when shooting handheld. The design of the 17-70mm includes state-of-the-art TSC material (Thermally Stable Composite), which allows for a durable construction as well a reduction in size by 30% compared to conventional models. Two FLD glass elements (with performance equal to fluorite) are incorporated along with one SLD element to reduce color aberration at the highest degree and obtain unmatched image quality. The 17-70mm F2.8-4 Macro DC HSM OS is compatible with the Sigma USB dock for an increased level of customization, including firmware updates as well as focus parameter adjustment changes. The perfect all-purpose travel lens, the 17-70mm F2.8 Macro DC HSM OS is a must have for any camera bag.

Sigma 18-250mm F3.5-6.3 DC Macro OS HSM (Pentax) - SM883109
Product Overview
The addition of the 18-250mm F3.5-6.3 DC Macro OS HSM speaks to Sigma’s versatile product lineup with this multipurpose zoom lens that offers Optical Stabilization (OS)* and covers wide angle to telephoto to macro photography. It differs from Sigma’s current 18-250mm F3.5-6.3 DC OS HSM lens with its even more compact size, its macro capability with a maximum magnification ratio of 1:2.9 and the use of Thermally Stable Composite (TSC) material currently used only by Sigma.
TSC, which is incorporated into the lens barrel and is often compared to polycarbonate, has a high degree of elasticity and exhibits little variation in its structure in extreme temperature conditions. This means that internal barrel expansion and contraction due to extreme temperature variations is less prevalent. TSC also contributes to the lens’ size reduction. The non-macro 18-250mm F3.5-6.3 without TSC weighs 22.2 ounces and is 3.1 by 4 inches in diameter, whereas the new macro lens is 16.6 ounces and 2.9 by 3.5 inches in diameter.
Sigma optimized this lens’ power arrangement by incorporating double-sided aspherical lenses and reexamining the design to achieve a more compact filter diameter. The lens has an approximate 13x high zoom ratio with a filter size of 62mm in diameter. Sigma’s unique OS system, as well as one Special Low Dispersion (SLD) glass and three aspherical lens glasses, compensate for camera shake and enable correction of color aberration, respectively.
The new 18-250mm F3.5-6.3 DC Macro OS HSM lens is also equipped with Super Multi-Layer Coating to reduce flare and ghosting, a Hyper Sonic Motor (HSM) to ensure fast and quiet auto-focusing, and a rounded, seven-blade diaphragm to create an attractive round blur to the out of focus areas. The lens features a brass-made bayonet mount applied on the surface to reinforce strength for long-term use and enable high accuracy and solidity.

Product Overview
Sigma’s APO 50-500mm F4.5-6.3 DG OS HSM is an advanced optical design of this 10x power high-performance zoom lens that covers the standard-to-super-telephoto range, now with the added advantage of Sigma’s own Optical Stabilization which offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. Sigma is the only one to offer OS for Sony and Pentax mount where the image is stabilized in the viewfinder if chosen.
For many photographers, having an “all-in-one” lens is an absolute dream. Especially for nature photographers, the idea of a lens suitable for landscape photography at the short end of the zoom range, while still having enough reach for wildlife is a great option. Add to that, the ability to close focus on small objects in the field such as flowers and it’s the perfect backpackers’ lens. Four SLD (Special Low Dispersion) glass elements provide optimum color correction & sharpness throughout the entire zoom range and Super Multi-Layer Coating reduces flare and ghosting and assures high image quality throughout the entire zoom range. With no need to change lenses, there is less chance of dirt or moisture entering the camera and fouling the imaging sensor.
The filter size of this lens is diameter 95mm and the lens is supplied with a step down ring enabling digital cameras with an APS-c size image sensor to use an diameter 86mm filter.

The Sigma 8-16mm F4.5-5.6 DC HSM is an ultra-wide angle lens designed specifically for APS-C DSLRs. FLD glass elements (with performance equal to fluorite) help compensate for color aberration while a hybrid aspherical lens and two glass mold elements provide excellent correction of distortion and astigmatism. A highly creative tool, the Sigma 8-16mm 4.5-5.6 DC HSM features an inner zoom system as well as the feature of full-time manual focus override. Ideal for a variety of photography subjects including landscape photography, architectural photography, wedding photography, photojournalism and interior photography to name a few.

This lens offers an f/2.8 maximum aperture throughout the entire zoom range, to ensure stress-free photographic shots at all focal lengths and distances. Additionally, a broader photographic expression through the use of faster shutter speeds as a result of the maximum aperture offers enhanced photographic pleasure.
Note: Di-II lenses cannot be used with digital SLR cameras using image sensors that are larger than that of an APS-C size imager (e.g. 1D series), or with 35mm film SLR cameras.
- Optimized for Digital SLR
- The use of XR (Extra Refractive Index) glass optimizes the overall distribution of optical power, and also reduces various aberrations to the absolute minimum while achieving remarkable compactness. In addition, suitable positioning of two hybrid aspherical elements serves to maintain imaging performance and to shorten and compress the entire optical system.
- LD Glass
- An LD (Low Dispersion) glass element is used to accomplish effective compensation of on-axis and lateral chromatic aberrations, a critical factor for enhancing optical quality in digital photography, in order to achieve outstanding optical performance over the entire zoom range.
- Enhanced Peripheral Illumination
- Peripheral light fall-off is minimized when compared with that of conventional lenses for film cameras, so images are uniformly bright from the center to the periphery.
- Internal Surface Coating to Reduce Ghosting and Flare
- By employing "Internal Surface Coatings" (i.e., multiple-layer coatings on cemented surfaces of plural elements) and multiple-layer coating technology on ordinary elements, ghosting and flare due to the reflections that occur when light enters through the front element and reflections caused by the imagers themselves are reduced to the absolute minimum.
- Zoom Lock Mechanism
- The Zoom Lock prevents unwanted barrel extension when carrying the lens/camera combination.
