The Sigma 28-70mm F2.8 DG DN C is a highly versatile, full frame lens for L-mount mirrorless cameras. This lens is perfect for a wide range of photographic applications including landscapes, portraits, weddings, street, close-ups, and architecture. It’s lightweight, super-portable, and also ideal for video shooting. Despite weighing less and being far more compact, this lens produces stunning results thanks to being based on the professional Art Series model. It redefines the standard zoom for mirrorless cameras by combining outstanding optical performance, an f/2.8 constant aperture, and a lightweight and compact body. The design is based on the existing 24-70mm f/2.8 DG DN | Art, but with a focal range starting at 28mm, making the lens body significantly smaller and lighter while maintaining superb optical performance. It is the smallest and lightest lens in its class. Remaining true to the Contemporary line's core concept of maintaining an optimal balance between optical performance and lens size, this new optic delivers professional quality results in a body small enough to take on a casual outing. In addition to prioritizing portability, Sigma’s optical engineers introduced a new combination of coatings and structural elements that make this standard zoom well-equipped for use in a wide range of shooting environments. Likewise, the latest production and manufacturing techniques were employed to ensure exceptionally high build quality. The 28-70mm f/2.8 DG DN | Contemporary introduces another fast, high-performance, large-aperture zoom lens to Sigma’s mirrorless line-up, offering a more compact alternative to the existing 24-70mm f/2.8 DG DN | Art.
