New Sigma 70-200mm F2.8 Sport The continuous evolution of the 70-200mm is now available for the Sport line, offering all the features required by professionals. To make the lens light, sturdy, and easy to handle, a magnesium alloy has been used. Like other lenses in the Sports line, it has a dust- and splash-proof structure, along with water- and oil-repellent coating on the front lens. Therefore, it ensures safe use even in the most difficult shooting conditions. It incorporates 10 special low-dispersion optical glass elements. To provide excellent correction of chromatic aberration, it incorporates nine FLD glass elements and one SLD glass element, for a total of ten low-dispersion glass elements. From the center to the corners of the image, the resolution is extremely high, making the lens capable of meeting the needs of professional photographers in the most diverse shooting conditions. By optimizing spherical aberration, a natural bokeh effect is guaranteed, making the lens perfect for portraiture.
