to put it simply in layman's terms, making lens that can capture 720x576 pixel is less complicated/cheaper than making lens that can capture 1080p image size.
well say for instance, we compare a cheap 1080p that can do 50x zoom, and a pro-grade camera that can do 5x zoom. assuming everything else are equal, most definitely the optics for the pro-grade cam is a lot better - usability, no chomatic aberration, sharper, smoother operation, no purple fringing, better lowlight capture, etc.
a simple way to view it, not necessarily true but generally this is the idea:
cheap lens:
expensive lens:
check the lens shape and see how much more complicated the expensive one really is! you can have 1000x zoom even (just put the cam at the back of a telescope lah!), but it's not gonna be pretty
