Worksheet: Fill out the worksheet in class as we learn about the different types of lenses. Wide Angle Lens: focal length is substantially smaller than the focal length of a normal lens for a given film plane. Great to show more SPACE in the frame Prime Lens: a lens of fixed focal length. they're usually 'faster'. This means they have a larger maximum aperture, which enables quicker shutter speeds. For example, a typical 18-55mm zoom lens has a maximum aperture of roughly f/4 at the wide-angle end, shrinking to a mere f/5.6 at about 50mm. Telephoto Lens: a lens with a longer focal length than standard, giving a narrow field of view and a magnified image.
Standard (normal) Lens: has a fixed focal length (50mm, 85mm, 100mm), and reproduces fairly accurately what the human eye sees – in terms of perspective and angle of view. For a 35mm film camera or a full-frame DSLR, the 50mm lens is considered standard. Macro Lens: a lens suitable for taking photographs unusually close to the subject. ZOOM LENS a lens allowing a camera to change smoothly from a long shot to a close-up or vice versa by varying the focal length. |
