Join Ben Long for an in-depth discussion in this video Focus modes, part of Nikon D7000 Essential Training.
Your camera's Autofocus is pretty amazing. It's speedy, it's able to work in surprisingly low light and it's often able to figure out exactly what your subject is. For most situations, Autofocus will give you all the focusing power that you need. Your Autofocus mechanism can work in two different ways. first, that's the way we've already discussed to you. Half-press the shutter button and the camera focuses and locks focus and then lets you know that it's ready to shoot or it can work in a servo mode. If you frame a moving subject, the camera will track that moving subject and keep it in focus.
Your camera has several different servo features, and three different focusing modes. Your current focus mode is indicated right here on your viewfinder. That AF-A that's Auto Servo Autofocus, in that mode the camera will automatically try to determine whether it should be tracking a moving object or just engaging in normal locking autofocus. That's going to be the best mode choice for the majority of your shots. However, if you know that you're shooting a moving subject, then you may want to lock the camera into a Continuous Servo Autofocus mode, so that it absolutely will track a moving subject and not fall into just trying to fix focus.
Conversely, if you are shooting that you know is going to standstill, you may want to lock your camera into single servo focus, so that it won't start trying to track something, say if it moves a little bit or if you move the camera around. To change focus mode, you come over here and your autofocus manual switch here also has a button in the middle. I can push a button to change autofocus mode. So let's go back and you can see what happens when I push the button. When I press it, my LCD view screen up here goes blank, and only my focus controls are left.
Now if turn the main dial, I can switch from AF-A that's Auto Servo Autofocus, to Single Servo Autofocus. That's going to be what I want to use if I am shooting something that I know is not moving and then I can go to Continuous Servo Autofocus, this is what I want to use if I know that my subject is going to be moving. Again, most of the time, you'll be fine sitting on the automatic mode.
