oh. so you've gotten your camera already?
Set your shooting mode to A Mode (Aperture Priority)
go to the Camera Icon Menu, select Focusing Mode and set it to MF (Manual Focus)
go to the settings (red toolbox) and look for the option MF Assist. set it to the timing you want.
now when you use the focusing ring to adjust focus, you'll notice that the screen zooms in. you can adjust where to place this area so as to adjust the focus based on the subject you want.
also... maybe you should consider going for the complimentary class. they'll teach you how to use your camera.
