The Tamron 35-150mm f/2-2.8 Di III VXD is an advanced all-in-one zoom characterized by its wide to medium-telephoto range and its bright maximum aperture. Versatile wide-angle to medium telephoto zoom lens is designed for full-frame Sony E-mount mirrorless cameras. Boasting a maximum wide-open aperture of f/2-2.8 means you can comfortably photograph in available light conditions while also controlling depth of field and isolating your subject matter with selective focus. VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism provides fast, quiet, and precise autofocus performance throughout the zoom range. Connector port works in conjunction with Tamron Lens Utility software for customizing lens functions and updating firmware through the lens rather than through the camera. Updated design for enhanced operability and ergonomic texture.
