The Sigma 24-70mm f/2.8 DG DN II Art Lens for Sony E-mount cameras exemplifies the fusion of advanced optical performance with a compact and lightweight design. This flagship lens, which is a significant upgrade from its predecessor, is engineered to deliver exceptional sharpness, resolution, and portability, making it ideal for a wide range of photographic applications. The optical design of the lens is particularly sophisticated, incorporating six "F" Low Dispersion (FLD) elements, two Special Low Dispersion (SLD) elements, and five aspherical elements. This combination effectively mitigates chromatic aberrations and color fringing, resulting in superior clarity and color accuracy throughout the zoom range. The lens's super multilayer and nano porous coatings further enhance image quality by minimizing lens flare and ghosting, ensuring contrast-rich and color-neutral imagery even in backlit conditions. The lens is also designed with video recording in mind, featuring a reduction in focus breathing, which helps produce natural-looking focus pulls. The introduction of a high-response linear actuator (HLA) enables autofocus speeds that are over three times faster than previous models. Additionally, the lens offers a minimum focusing distance of 6.7 inches and a maximum magnification of 1:2.7, making it suitable for close-up work and tight spaces. Despite its advanced features, the lens is built to be both durable and compact. It measures just 4.8 inches in length and weighs 1.6 lbs, making it easy to handle and carry. The robust internal structure includes metal parts, while the exterior features rubber seals to protect against dust and moisture. User-friendly elements like a clickable aperture ring with lock switches, integrated AF-L buttons, and a zoom lock switch enhance the lens’s practicality.
