Featuring three Special Low-Dispersion elements and four aspherical elements, it minimizes chromatic aberrations and distortion, ensuring sharp, vivid imagery across all focal lengths. The fast f/2.8 aperture excels in low light and delivers beautiful bokeh, ideal for portraiture and event photography. Its Optical Stabilization (OS) system and Hypersonic Motor (HSM) autofocus ensure sharp, stable images and quick, silent focusing. Durable and weather-sealed, this lens is perfect for challenging environments, making it a top choice for photographers of all levels seeking a reliable, high-performance lens for diverse shooting scenarios.

More Details:

• Advanced Optical Design: This lens is a part of Sigma's prestigious Art line, integrating three Special Low-Dispersion elements and four aspherical elements. This combination significantly reduces chromatic aberrations and distortion, ensuring crystal-clear images throughout the zoom range.

• Superior Low-Light Performance: With a constant f/2.8 aperture, it offers exceptional performance in low-light conditions, along with the ability to create stunning bokeh effects, perfect for portraits and event photography.

• Enhanced Stability: The Optical Stabilization (OS) feature of Sigma effectively counters camera shake, allowing for sharp, handheld photography even in dim lighting or at extended focal lengths.

• Rapid Autofocus System: Equipped with Sigma's Hypersonic Motor (HSM), the autofocus is not only fast but also quiet and precise, essential for capturing quick moments and maintaining focus accuracy in dynamic settings.

• Robust Construction: Built to endure, the lens boasts a high-quality, dust- and splash-resistant design, making it an ideal companion for challenging outdoor shoots and adventurous photography.

• Versatility in Focal Range: Offering a 24-70mm zoom range, the lens covers a wide spectrum of focal lengths, adaptable for various photography styles including landscapes, street photography, and travel.

• 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.
• 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.
• 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.
• 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.
• Mount with Dust and Splash Resistant Structure - Since the area of the lens most vulnerable to dust and other foreign bodies is the mount, rubber sealing* helps provide peace of mind. In addition, the front lens element features a water- and oil-repellant coating that helps the lens perform well in the rain, near water, and in other challenging conditions.
• 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.
