if you want to see if your camera motion is good without rendering for real, you can just do a playblast (windows->playblast) and maya will basically create a quick and dirty animation comprised of screenshots to give you an idea of how the motion will look.

make sure you have the view you want the playblast to be for as the selected viewport. if you've got an animated camera, change one of your viewports to the camera you've got animated with panels->then choose the camera name... then click playblast, wait a few seconds, and watch away!
