The lens features advanced optical elements that minimize aberrations, ensuring sharp, clear images. Additionally, its Optical Stabilizer significantly reduces camera shake, and the Hyper Sonic Motor offers fast, silent autofocus. Built to endure tough conditions, it's dust and splash-resistant, and its future-proof design is optimized for today's high-resolution cameras. While its weight and cost might be considerations for some, the Sigma 24-70mm F2.8 is an excellent investment for professionals seeking a versatile, high-quality lens.

More Details:

• Advanced Optical Design: Minimizes aberrations for unparalleled edge-to-edge clarity at all apertures.
• Pleasing Bokeh Effect: 9-blade rounded diaphragm ensures smooth, aesthetically pleasing out-of-focus areas.
• Effective Image Stabilization: Optical Stabilizer (OS) compensates for up to 4 stops of camera shake, enabling sharp handheld photography.
• Rapid and Silent Autofocus: Equipped with Hyper Sonic Motor (HSM) for quick, quiet focusing, essential in varied lighting conditions.
• Durable Build for Harsh Conditions: Dust and splash-resistant construction, ready for challenging environments.
• Future-Proof Design: Optimally engineered for high-resolution digital cameras, ensuring longevity and compatibility.
• Super Multi-Layer Coating: Reduces flare and ghosting, enhancing image contrast and quality.
• Close Focusing Capability: Achieves a minimum focus distance of 37cm (14.6"), adding versatility in composition.
• High-Quality Construction: Metal barrel construction ensures durability and long-term performance.
• Front Element Protection: Water and oil repellent coating safeguards against dirt and moisture.
• Customization with Sigma USB Dock: Allows for fine-tuning of lens settings and firmware updates, ensuring peak performance.

• 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.
