A quick question regarding manual focus (1 Viewer)

Due to the detritus vines & pine straw hanging all over the place, auto focusing is proving to be a drain on me and the battery so I've switched over to manual focusing with my tamron 200-500mm & nikon d50.

Now, I've simply switched the outside camera body switch to manual but was wondering if I should also be changing the camera setting in the menu to turn off auto-focus or does is matter at all?

There's a switch on the camera, and another one on some lenses. As long as both of these are in the manual position, you should be okay. I don't change any camera menu settings on the D300 and D80.
