Tamron 150-500 lens for Sony cameras

As clearly stated in the title, the lens is compatible with Sony A74 cameras and comes with a tripod. + A new tripod stand for the lens, camera, and mobile phone. I've had the lens for a week; it's still in its original box. I ordered it from Abdulwahid's website and it includes a three-year warranty. Its price on the website is 5300. Reason for selling: I need the money for an external course.
