Josh, you are correct. A full screen zoom can be toggled by pressing 
Command-Option-8 or in the Universal Access pane of system preferences, just as 
VoiceOver is. Selecting options on that pane also gives you choices for maximum 
and minimum levels if you frequently use a certain magnification range.  There 
are also options there to have it track the keyboard focus and mouse pointer, 
much as I am sure you are used to, and to have it smooth text and images.  
Magnification is changed either by using Command-Option and the plus or minus 
keys, or by holding the control key and scrolling with the mouse wheel or 
trackpad.  Below the magnification section of Universal Access are display 
options.  They allow you to invert screen colors, set the screen to grayscale, 
and increase contrast, if that is useful to you.  This is all separate from the 
magnification provided in VoiceOver, which only magnifies the area that 
currently has focus.

While I don't use magnification myself, it is my understand that
VoiceOver's magnification features are specific to certain areas,
while the Mac's Zoom Magnification feature is full screen.  Again, I
don't use these features so am not sure of the finer points. Hope this
helps.
