Tokina 28-70mm f/ 2.8 AT-X AF Handling and Mechanics

The lens is well assembled in a metal barrel. It looks compact compared to other zooms such aperture and focal length. It has two rubberized rings. To focus closer to the front lens and the zoom - closer to the camera. There is a distance scale markings 28, 35 and 50 mm and window with range of focus. Tokina 28-70mm f/ 2.8 AT-X AF  

Focusing

The lens has autofocus. When focusing, the front element rotates. rotation angle - 45 degrees. Wherein the front element extends 4mm. In the version for Nikon AF system is designed for a screwdriver, so the autofocus works only on older models of cameras. Autofocus is fast, but sometimes greased. I use this lens with Nikon 3100 and focusing manually. Focusing ring rotates 45 degrees is very small, which requires accuracy hover. In the APS-C camera focal length of 28-70 mm equivalent of 42-105 mm.

MFD is 0.7m, which is quite a lot for such a focal macro and it is not to shoot.
