I have been searching online for an answer and all I'm getting is contradictory information.
Can I manually focus this lens if both the camera a Nikon d90 and lens are both in autofocus mode. E.g. After the lens has autofocused I can adjust manually if the focus isn't quite right.

Thanks Gerard.

Yes you can. The AF-S lenses have manual focus override. I use that quite often.

That's great to know. I was afraid I might damage some inner workings of either the camera or lens if I used the manual focus whilst both in auto.

I suppose it's better to shoot in single rather than continuous mode as I presume the autofocus will be continually hunting or does it not make a difference in reference to using the manual focus.

Regards Gerard.

Many of us set the shutter release button to release the shutter (and activate VR in VR lenses) but not to focus; and we use the focus button on the back of the camera to focus. So you focus (using your thumb) then release and either manually refocus the lens or simply reframe the subject for better composition without changing focus when you press the shutter release.
It sounds awkward but you get used to the thumb and finger action very quickly.

Thanks Bill I'll play around with the settings to see which I find the most useful.
