Reason why I’m selling this lens is because I recently purchased three prime lenses and at this moment I do not need a zoom lens. This lens has only been used about 7 photo sessions. The price is final. * Tamron 28-75mm F/2.8 Di III RXD . A high-speed standard zoom lens for Sony full-frame mirrorless cameras, Model A036 delivers superb optical performance, including both outstanding image quality and beautiful background blur effects (bokeh). Photographers may enjoy dynamic wide-angle expressions like never before thanks to a minimum object distance of 7.5 in at the wideangle zoom setting. Usefulness and versatility are enhanced by its compact size and light weight, measuring only 4.6 in and weighing 19.4 oz. Model A036 incorporates an all-new high-speed and precise AF driving system.
