I just got the Tamron A16S zoom lens for my Sony Alpha 350 DSLR. Its a zoom lens that goes from 17mm to 50mm and has a constant maximum wide aperture of f/2.8. The contents of the box include the lens, front and rear lens caps, petal shaped lens hood, and a plastic bag containing three pamphlets. One of the pamphlets is the instructions for the lens, in eight different languages. There is also a pamphlet with suggestions on how to use the lens and finally another on how to safely operate and care for your lens.
