Guys,

I think of getting Tamron AF 18-200mm F3.5-6.3 XR Di II to replace my D5000 kit lens AF-S DX NIKKOR 18-55mm f/3.5-5.6G VR. Coz Tamron seems like will cover all my needs. But is it the lense got autofocus with my Nikon D5000? And is it any good the Tamron vs my kit lens. Sifu's advice needed. Thanks.
