Abstract
A hybrid lens system includes, in order from an object side to an image side, a positive first lens formed of glass, a negative second lens, a positive third lens and a negative fourth lens. The second, third and fourth lenses are all formed of plastic. The first, second, third and fourth lenses have aspheric surfaces. By using the hybrid lens system, advantages can be obtained in friction and scrape resistant, being affected less by the surroundings and suiting to be used in mobile phones.
