1. CAMERA LENS

2. Why use lens? • selects and directs the light rays entering the camera • brings light from the subjects into focus on the film DEVC151: CAMERA LENS

3. Major types of lens POSITIVE LENS • convergent lens • bens light rays inward • convex lens • forms upside down and reversed image DEVC151: CAMERA LENS

4. Major types of lens NEGATIVE LENS • divergent lens • bens light rays outward • virtual image can be formed since the light rays do not converge DEVC151: CAMERA LENS

5. BASIC PARTS OF A CAMERA LENS 1) Focusing Ring 2) Opening/ Aperture Ring DEVC151: CAMERA LENS

6. Types of camera lens * Camera lenses are categorized according to their FOCAL LENGTH * The larger the focal length, the larger the image produced. DEVC151: CAMERA LENS

7. Types of camera lens NORMAL LENS • most common and widely used • approximates the angle of view of the human eye • 35-55 mm angle DEVC151: CAMERA LENS

8. Types of camera lens WIDE-ANGLE LENS • has shorter focal length • landscapes • not good in focus • gives a wider view but smaller image the normal eyes can see • 24-35 mm DEVC151: CAMERA LENS

9. Types of camera lens TELEPHOTO LENS • has longer focal length • magnifies distance • 85-135 mm range * The longer the focal length, the greater the magnification. The narrower the angle of view, the less background. DEVC151: CAMERA LENS

10. Types of camera lens ZOOM LENS • shift to normal to telephoto DEVC151: CAMERA LENS

11. Types of camera lens FISH-EYE LENS • curve lenses to achieve fish-eye effect • rounded image DEVC151: CAMERA LENS
