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 30mm F1.4 ART DC HSM (Pentax)
$ 499.00
Sigma 30mm F1.4 ART DC HSM (Pentax)
Sigma SKU: 301109 | Helix SKU: SM301109
Overview
Placed in the Art line, this large-aperture standard lens with an angle of view equivalent to 45mm on a 35mm camera is a superb go-to lens for artistic photography on an APS-C format digital SLR. Offering the bright F1.4 aperture and an angle of view extremely close to that of human vision, this lens is ideal for many different types of photography. Equipped with the latest in lens technology, the 30mm 1.4 lens Art boasts a Hyper Sonic Motor (HSM), Super Multi-Layer Coating and a design featuring Thermally Stable Composite Material (TSC). The HSM ensures quiet, accurate and high-speed autofocus; the Super Multi-Layer Coating reduces flare and ghosting, while the TSC reduces expansion and contraction of the internal lens barrel. A rear focus system prevents focus-dependent variation in aberration, making high-level image quality possible throughout the entire image. With their unchanging barrel length, these lenses also enhance balance and stability for the photographer. An optimized autofocus algorithm achieves smooth focusing while a 9 blade rounded diaphragm creates beautiful bokeh. Under the Global Vision standard, every lens will be tested before shipping using the Sigma A1 MTF system to ensure the highest degree of quality possible and also features capability with the USB dock.
