I don't have one on mine either - mine is a Pentax fit so it doesn't have HSM perhaps that's why. What camera do you have?

Do believe it's about Stabilization,or you can call it Steady Shot or Anti Shake. Pentax and Sony use in camera Stabilization. Where Canon puts it in the lens
So if you have a Sony/Pentax, you don't need a switch on the lens. Any lens you put on these cameras will be stabilized. Just switch to MF or AF on the camera (your choice) and your good to go.

Anti Shake /Image Stabilization / Shake Reduction is not relevant to autofocus, and has nothing to do with the AF/MFswitch.
Canon lenses have the autofocus motors in the lenses, so required the switch there. Pentax motors were always in the body (yes, except for the very first lens-based one, if you're s stickler for detail), so the switch is in the body. Now with SDM/USM drives it's not so relevant, since these drives don't require the mechanical clutch action to disengage the drive. But in the name of compatibility, it sticks.
Curiously, some new Pentax lenses have the switch. What are you telling us Pentax? Your next body won't support body-motor-driven lenses and won't have the mechanical switch/clutch?

I've got a Nikon D60 but bought the lens on a whim. Seems Ok though, the limited time I've had to play with it. Going out tomorrow in the Snowdonia National Park to see what I can get from it. Thanks for the replies.

You can switch off the auto focus using the menu on your DSLR; on my Nikon DXX the menu option can be found at;
Menu > Custom Setting Menu (pencil icon) > Focus Mode
Hope this helps somebody! Of course, you will have to switch autofocus back on again if you wish to use a lens' own switch (i.e. another lens which does have a switch).

Are you sure? My D80 doesn't have that. I have a physical switch by the lens barrel. Seems awfully weird to bury such an important control in a menu. And I'm sure your DXX has that switch as well. Why have both? Can anybody confirm that?

Tim, you don't say what you're shooting, but it looks like it's a Nikon D40. I'm no Nikon expert -- I'm allergic, but it's an (ahem) affordable (in their words) Nikon. Meaning it's been cut down in features/cost. Emasculated even, some would say. So it doesn't offer support for the lenses that require the on-body AF/MF switch. (edit: meaning it doesn't have an in-body focus motor, and won't drive AF or AF-D lenses, a quick google search tells me)
It's pretty clear: Canon mounts need the switch on the lens.
