Combining excellent optical quality with a number of advanced features
Bringing a new experience to high-power zoom lenses
Small size, 28mm focal length provides F/2.8 aperture, high pixel and high resolution, all-round use
Tamron's lens designers have been working on high-power zoom lenses for many years, the new Sony E-Mount 28-200mm F/2.8-5.6 Di III RXD (Model A071) high-power zoom lens, combined with Tamron's accumulated development experience, the lens is the first in 28mm Provides F/2.8 aperture design at wide-angle focal length. On the other hand, even at the 200mm focal length at the telephoto end, the lens still maintains an aperture of F/5.6, making it the highest-power zoom lens with the largest actual aperture value in history. At the same time, the lens body remains lightweight (117mmx 74mm and 575g).
In order to ensure that this high-power zoom lens provides high-quality shooting performance, the lens designer has added a number of special lenses in the optical process of designing the lens, including LD (Low Dispersion) low dispersion, XLD (eXtra Low Dispersion) ultra-low dispersion, die-casting Aspherical and composite design aspherical lenses ensure that the lens can effectively control chromatic aberration, improve contrast, provide good distortion control and improve sharpness at the center and edge of the picture. Since the lens combines many advantages, photographers can use this lens to capture different types of photographic subjects, including landscapes, street scenes, portraits and different photographic themes
