The Tamron 50-400mm f/4.5-6.3 Di III VC VXD for Sony E-mount mirrorless cameras is an ideal choice for photographing landscapes, wildlife, sports, portraiture, and more. Featuring an 8x zoom ratio that begins at 50mm, this remarkably compact and portable lens offers a length of just 7.2" making it the same size as conventional 100-400mm zoom lenses. With a minimum focusing distance of just 9.8" at the 50mm end, the 50-400mm provides up to one-half life-size magnification for close-up shooting.VC (Vibration Compensation) system reduces camera shake and facilitates shooting at longer focal lengths and slower shutter speeds. For staying up-to-date and customizing your lens for maximum performance, the lens features a USB Type-C connector port for Tamron Lens Utility software, which enables you to customize functions and update the firmware for the lens by using a computer.
