Sigma 24-70mm F2.8 DG OS HSM Art Lens for Sigma SA

Sigma 24-70mm F2.8 Art Lens: Versatility Meets Excellence

Overview:

The Sigma 24-70mm F2.8 DG OS HSM Art Lens stands out as a premium choice for Sigma SA-mount full-frame DSLR users, offering an exceptional blend of image quality and versatility. This lens is a part of Sigma's esteemed Art series, known for its superior optical performance. It features a fast f/2.8 aperture, ensuring consistent brightness throughout its zoom range, which is ideal for low-light conditions and achieving a shallow depth of field with stunning bokeh. The lens' optical image stabilization (OS) is a significant advantage, providing sharp, handheld images even at slower shutter speeds. The inclusion of a Hypersonic Motor (HSM) ensures fast, quiet, and accurate autofocus, crucial for capturing quick movements and spontaneous moments. Additionally, its durable, weather-sealed construction makes it reliable in various shooting environments. With a focal length range that covers wide-angle to portrait, this lens is incredibly versatile, suitable for everything from landscapes and portraits to weddings and event photography. The Sigma 24-70mm F2.8 lens is an excellent investment for photographers seeking a high-quality, adaptable lens that delivers professional-grade results.

More Details:

• Exceptional Image Quality: Leveraging the Art series' advanced optical design, this lens integrates three SLD and four aspherical elements, minimizing aberrations for crisp, high-resolution images across the zoom range.
• Fast f/2.8 Aperture: The constant f/2.8 aperture ensures ample light intake, perfect for low-light conditions and creating beautiful bokeh with a shallow depth of field.
• Optical Image Stabilization (OS): Combat camera shake effectively, enabling sharp handheld shots even at slower shutter speeds.
• Hypersonic Motor (HSM): Experience rapid, silent, and precise autofocus, essential for capturing spontaneous moments and dynamic scenes.
• Robust Construction: Its weather-sealed design offers protection against dust, moisture, and splashes, ideal for challenging environments.
• Versatile Focal Length: Covering a wide-angle to portrait-length range, this lens is excellently suited for various photography styles, from everyday shooting to specialized subjects.
• Comprehensive Features: With a 24-70mm focal length, f/2.8-f/22 aperture range, and a host of other specifications, this lens is equipped to meet diverse photographic needs.

• Fast AF with full-time manual focus - Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.
• Outstanding optical performance - Three SLD glass lens elements and four aspherical lens elements help minimize optical aberrations. To ensure outstanding image quality from the center to the edges of the photograph, the optical system minimizes coma, which causes points of light to streak, and transverse chromatic aberration, which cannot be corrected by adjusting the aperture.
• Incorporating advanced aspherical lens processing technology - Aspherical lenses necessitate refined expertise in the design and manufacturing of advanced, high-performance lenses. This lens incorporates an aspherical lens element that helps achieve extremely high resolution.
• Bokeh that is a cut above - At wide-open aperture, this lens offers outstanding photographic expression. The area in focus is extremely sharp, while the background exhibits a beautiful bokeh effect with only slight spherical aberration. Since large-diameter zoom lenses are often used at wide-open aperture, SIGMA has paid close attention to the shape of the bokeh, aiming for perfect circularity.
• Designed to minimize flare and ghosting - SIGMA’s Super Multi-Layer Coating helps further reduce flare and ghosting and provides sharp, high-contrast images even in backlit conditions.
• Incorporating the OS function for success on any shoot - Designed for use in a wide variety of situations, the optical stabilizer (OS) offers a powerful stabilization effect of 4 stops.
• Exclusive low-dispersion glass - Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite.
• Newly designed HSM for fast AF performance - The newly designed hypersonic motor (HSM) offers 1.3 times the torque of its predecessor. Even at low speeds, it offers exceptionally stable performance.
• Rounded diaphragm - The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
• High-precision, rugged brass bayonet mount - The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
