Tamron announced three prime lenses for Sony full-frame mirrorless cameras: 20mm F/2.8 Di III OSD M1:2 (Model F050), 24mm F/2.8 Di III OSD M1:2 (Model F051), and 35mm F/2.8 Di III OSD M1:2 (Model F053). Each lens strikes a balance between gorgeous image rendering and superior operation. All three have the same Ø67mm filter size, the same as Tamron 17-28mm F/2.8 and 28-75mm F/2.8, for hassle-free sharing of lens caps and filters between all five lenses. The 20mm, 24mm and 35mm lenses are all capable of focusing very close, to an unprecedented in this category magnification ratio of 1:2. Other features include Moisture-Resistant Construction and a Fluorine Coating on the front element for easy maintenance and fingerprint removal. They also support various camera features offered by certain Sony cameras, such as Fast Hybrid AF and Eye AF, and offer a multitude of advanced functions to ensure a pleasant shooting experience and fantastic results. At the same time, Tamron announced the development of its fast tele zoom to complete the f/2.8 trinity for Sony full-frame mirrorless.
