The Tamron SP 150-600mm f/5-6.3 Di USD Lens for Sony is an expansive telephoto-zoom lens designed for both full-frame and APS-C-sized image sensors. Its 4x zoom design covers standard telephoto to super telephoto perspectives, making it ideally suited to working with a wide variety of subject matter. A USM (Ultrasonic Silent Drive) autofocus motor provides quick and precise focusing performance, with high torque, low response times, and quiet operation to benefit both still and video applications. Additionally, a full-time manual focus mechanism enables manual fine-tuning of focus at any point, even when the AF system is engaged.
The optical design integrates three low dispersion (LD) elements within its construction to minimize optical aberrations throughout the zoom range, particularly at the longer focal length positions. Individual elements also feature an eBAND (Extended Bandwidth & Angular Dependency) coating, as well as a conventional BBAR (Broad-Band Anti-Reflection) coating, in order to reduce lens flare and ghosting to produce more contrast-rich and color-neutral imagery.
