Newb Question RE:Tokina 28-70 F2.8 On D60
Just bought this outfit used but in super nice condition.The Tokina is marked AF which I assume is auto focus but the menu in the D60 is grayed out and set to MF.Is the lens in fact AF or am I doing something wrong?From Photozone:

The lens features a so called focus-clutch mechanism which allows you to change between AF and MF operation by pushing/pulling the focus ring. Unfortunately it is a quite imperfect implementation because this can only be done at the infinity setting (the AF 28-80mm f/2.8 AT-X Pro doesn´t suffer from this limitation). However, you can also use a conventional AF/MF switch for doing so. The AF speed of the lens is quite good though nothing to rave about. The noise during AF operation is relatively low but well noticeable (standard AF micro motor).

Not sure how this works...any help is appreciated.

Some camera require yhou to fine tune the menu settings to use the App rin on lenses and use older AF focus lenses. I am not fimilar with D60 camera but on my Pentax K-5 I have to set a menu option to on or my older 50mm will not work on my camera at all. Hopes this gets you going in the right direction

The D60 doesn't have a focusing motor, and neither does the Tokina 28-70 AIUI. However, since the lens is AF, it provides all the information to the camera that any other AF lens does -- it just doesn't have a motor to make use of that information. You should be able to use the RangeFinder option in the viewfinder (user manual page 61), and use your wrist as the "focus motor" to achieve ths same focusing you would have gotten with auto-focus.
