Lenses, most of the modern ones I know of are like this with cameras. Controls are in the camera for the most part.
Be careful of your lenses, if you have others to not try manual focus unless you have read the manual on it. I know that seems silly, but I have a friend that can't seem to break herself of the habit of wanting to grab the lens to manually focus when I have it set to AF. You can eventually mess up a lens doing that. Some lenses have a switch on the side for switching but you have to remind yourself to use it. LOL
