  • diameter 71 mm
  • AD06 petal hood included

The Tamron AF 28-200mm F/3.8-5.6 XR Di Aspherical (IF) Macro(Model A031)  is universal full-format 7x zoom lens, specially designed for full-format digital SLR cameras, but it can easily be used on film and small-format digital cameras with a range of efficient focal lengths of 44-310 mm. The compact and lightweight lens is convenient as an all-in-one lens for full-format camera; a small-format camera lacks for wide angle.

The optical scheme of the Tamron AF 28-200 mm f/ 3.8-5.6 XR Di Aspherical (IF) Macro  employs 15 elements in 14 groups, including 3 hybrid aspherical and two XR (Extra Refractive Index) elements. The lens features multicoating, minimizing flare and ghosting, and coated inner surfaces.

The lens is equipped with a zoom lock mechanism at 28 mm, which prevents barrel extension under its own weight when the lens is directed downwards..

Due to the absence of  a built-in AF motor the Tamron AF 28-200 mm f/ 3.8-5.6 XR Di Aspherical (IF) Macro operates in Manual Mode only with the Nikon bayonet mount on low-end D40, D40X, D60 cameras. 

Evaluation of  designations:

  • AF : autofocus
  • Di (Digitally integrated) - optimized for full-format digital cameras
  • XR- eXtra Refractive Index glass can bend light rays at steeper angles, thereby decreasing the physical length of the lens while enhancing imaging performance by minimizing optical aberrations
  • ASL (ASphericaL) - one or several aspherical elements
  • IF - internal focusing (the lens does not extend, the front element does not rotate)
  • Macro - macro mode

The 5-year warranty extends to all Tamron lenses officially imported to the Russian Federation and purchased after September 1, 2010.  In order to get warranty you should get registered at the Tamron European website within two months after the lens purchase.  The warranty is valid only for the first registered buyer.
