The zoom range incorporates the 85mm focal length (often regarded as optimum for portrait shooting) and covers everything from full-body shots that include the surrounding area to sharp head-and-shoulders shots that stand out from a natural defocused “bokeh” background for which Tamron is renowned. The compact Model A043 is designed for fast handling and easy transport, measuring only 124.3mm (4.9 in) long and perfectly balanced. On the technical side, three optimally placed LD (Low Dispersion) glass elements and three hybrid aspherical lenses quash various optical aberrations. Autofocus is exceptionally quiet with improved precision and speed thanks to the OSD (Optimized Silent Drive) DC motor. Furthermore, the Model A043 incorporates the Dual MPU (Micro-Processing Unit) system, which strikes the perfect balance between AF performance and effective vibration compensation. For close-focusing, the MOD (Minimum Object Distance) is 0.45m (17.7 in) across the entire zoom range. Providing greater flexibility when used outdoors, a Fluorine Coating and Moisture-Resistant Construction deliver extra measures of protection. All in all, the new 35-150mm portrait zoom is the most useful and most creative lens a portrait photographer can own.
