The Tamron 28-75mm F/2.8 Di III RXD (Model A036) is a high-speed zoom lens specifically designed for mirrorless cameras. Now you can balance high image quality with beautiful “bokeh”. Specialised glass elements, including an XLD lens, produce superb resolution across the entire zoom range. It is lightweight and compact, weighing just 550g, with a total length of only 117.8mm. The lens captures fine details across the focus plane, delivering excellent image quality. What’s more, the highly rendered optical performance of the A036 supports the latest high resolution cameras, while providing all the characteristics of a fast aperture lens. Stunning bokeh spreads softly from the plane of focus to accentuate the subject, making this lens ideal for all types of photography, from portraits to landscapes to street photography. The minimum focus distance of 19cm at the 28mm wide-angle end achieves a maximum magnification ratio of 1: 2.9, with a working distance of just 5.7cm from the front element, for unique perspectives. Whereas at the 75mm telephoto end, the 39cm minimum focus provides an image magnification of 1: 4, allowing close-up shooting with a pleasantly blurred background similar to a macro lens. The AF drive incorporates an RXD (Rapid extra-silent stepping Drive) stepping motor unit. This allows a very high degree of accuracy for high-speed AF, allowing you to maintain razor-sharp focus when shooting moving subjects or filming video. The lens is remarkably quiet, eliminating concerns of drive sounds being picked up while shooting video. Tamron’s new 28-75mm zoom is compatible with many of the advanced features that are specific to mirrorless cameras. Depending on camera model, these include: Fast Hybrid AF, Eye AF, Direct Manual Focus (DMF), In-camera lens correction and Camera-based lens unit firmware updates. The Moisture-Resistant Construction and Fluorine Coating are additional benefits. Filter Size: 67mm
