Your best friend for maneuvering around the Perspective View is the three controls at the top right corner of the Canvas. The one on the far right controls the Z-space orientation: clicking and dragging upwards will send everything "out" into view, even items that are beyond the "Far Plane" of the Active Camera and Camera views. Pressing the Shift Key before you click on the control will "amplify" the movement behavior as you drag the mouse.
Using Perspective View will not move the camera in space. If Active Camera or Camera is selected, using these controls **will** change the camera's orientation in space!

You can always double click any of the three controls to reset the perspective view or Camera orientation to 0,0,0 and no rotation.
You also have these menu options at the bottom of the Camera menu (top left corner of the canvas):

For Frame Object and Focus on Object, you must select the corresponding layer or layers in the Layers list. These can be used in conjunction with the 3 camera controllers - just remember to select where you want the movement focus to be... it takes a bit of practice to make it all "flow" for you.
