Closeup and Macro

Macro means the optical ability to produce a 1:1 or higher magnification of an object on the sensor. Digital compacts generally have a minimum focusing distance of about 30 cm;the Macro mode allows the camera to focus closer to the subject therefore filling the frame.

By zooming in, the camera will actually force you further back from your subject before it achieves focus. The optical zoom is the range between the minimum and maximum focal lengths. Digital compacts have 3x, 4x, 5x or 10x optical zoom. This means that the size of the image projected on the sensor will be 3x larger at the telephoto end than at maximum wide angle.
