SIGMA 28-70MM F2.8 DG DN CONTEMPORARY SONY E

SIGMA 28-70mm F / 2.8 DG DN Contemporary Sony E Mount

The Sigma 28-70mm F / 2.8 DG DN Contemporary is a professional standard zoom lens in a compact housing. Exceptional optical performance is combined with fast and consistent 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 compromises have been made in terms of performance. The design includes three aspherical lenses, two FLD and two SLD. These ensure excellent correction for axial chromatic aberration and sagittal coma aberration to achieve uniform sharpness from center to corner. In addition, the super multi-layer coating and porous nanon ensure perfect control of flare and contrast-rich images in the backlight. Finally, the front lens has a water and oil repellent coating, making it easy to clean.
The 28-70mm weighs just 470 grams, making it practical to take anywhere. Its lightweight focusing element keeps the autofocus unit compact. Combined with the extremely quiet fast stepping motor, all of this results in responsive and near-silent autofocus performance. In keeping with the design concept of the Contemporary range, the lens features a dust- and splash-proof construction on the frame and smaller buttons. High-quality materials and technology ensure that all parts work and continue to function properly, even under extreme temperature fluctuations.
