SIGMA 28-70mm f/2.8 DG DN Contemporary Sony E mount
The Sigma 28-70 mm f/2.8 DG DN Contemporary is a professional standard zoom lens encased in compact housing. Outstanding optical performance is combined with a fast, constant aperture. This version has the Sony E mount.
The optical design is based on the 24-70mm f/2.8 DG DN from the Art range, but the lens is significantly smaller and lighter. Despite this, no concessions have been made in terms of performance. The design features three aspherical, two FLD and two SLD lens elements. These ensure excellent correction of axial chromatic aberration and sagittal coma aberration for uniform sharpness from centre to corner. In addition, the Super Multi-Layer and Nanon Porous Coating ensure perfect control of flare and contrast-rich images in backlighting. Lastly, the front lens features water and oil-repellent coating, making it easy to keep clean.
The 28-70mm weighs just 470 grams, which makes it practical to take with you on the go. Its lightweight focus element keeps the autofocus unit compact. In combination with the extremely quiet, fast-stepping motor, this all results in responsive and almost silent autofocus performance. In line with the design concept of the Contemporary range, the lens features a dust and splash-proof construction at the mount and smaller buttons. High-quality materials and technology ensure all parts work and continue to function properly, even under extreme temperature fluctuations.
