  "account": "The Sigma 50-120mm F2.8 DC OS lens, a telephoto zoom for APS-C format cameras, has impressed reviewers with its compact size, excellent optics, and fast, silent autofocus. Weighing in at just 390g and measuring less than 10cm in length, this lens is surprisingly lightweight and easy to carry around. Its moderate telephoto range of 75-180mm (equivalent to 80-190mm on Canon) makes it a versatile choice for portrait photography, close-ups, indoor sports, and capturing details in landscapes or architecture.\n\nOne of the lens's most notable features is its compact and lightweight design, making it an attractive option for amateur photographers. The lens is available in three mounts: Fujifilm X, Sony E, and Canon RF, providing users with a wide range of camera choices. While it lacks a Nikon Z version, the lens offers good value for money at its $799 / £699 price point.\n\nOptically, the Sigma 50-120mm F2.8 DC OS employs 18 elements in 13 groups, including one Low Dispersion (FLD), three Super-Low Dispersion (SLD), and four aspherical elements. This complex construction ensures corner-to-corner sharpness and minimizes aberrant color fringing throughout the zoom range. The lens also features Sigma's High-response Linear Actuator (HLA) for swift and silent autofocus, along with a minimum focus distance of 23cm at its widest position and 55cm at its longest.\n\nBuilt-in optical image stabilisation offers 6.5 stops of shake reduction at 50mm, dropping to 4.5 stops at 120mm. However, the lens's maximum magnification varies from 0.33x to 0.21x, making it less suitable for field sports or wildlife photography. Despite its limitations, the Sigma 50-120mm F2.8 DC OS stands out as a compelling option for APS-C users, particularly when compared to other large-aperture APS-C telezooms, which are often more expensive and larger in size.",
