Select these options via the View > Camera Settings panel menu.
By default, when you create a camera from the Create menu, the view is perspective. If you want an orthographic camera view, disable this checkbox. Alternatively, you can use the hotkey Alt + P to switch between the two. For more information on perspective and orthographic cameras, see Control which camera is shown in a view panel.
If on, all camera movements, such as tumble, track, and zoom, are written to the Command History or Script Editor (MEL journal), which lets you undo or redo camera movements or copy camera movements to use them for other cameras or scenes.
Undoable Movements is off by default, but you can still use [ and ] to undo and redo camera moves.
Select this option to ignore the 2D Pan/Zoom settings so that your scene view appears in the full camera view.
This feature is most useful if you have two panels and you want to work in the panned/zoomed detail region in one panel while working in the full camera view in the other.
