Jim is correct - we would need to know the focal length of the point and shoot because the 10X is 10 times that focal length.
For a 28-300mm lens the 28 side widens the view and the 300 side brings things closer. How close you can focus depends on how the lens is constructed. Best way to learn is to play though....but that 28-300mm lens should be very versatile.
hope that helped a bit...
What camera did you buy?
