After performing the preliminary steps as presented in "Preparation for Use" (pages 8 ~ 12), shooting with the Nikon EL2 is as simple as: 1) Set the shutter speed dial to " A " to prepare the camera for automatic operation, as detailed on page 13. 2) Set the lens aperture to the setting appropriate for the shooting situation at hand by turning the aperture ring, as detailed on page 14. 3) Turn on the meter and shutter control by simply moving the film-advance lever to the 30° standoff position, as detailed on page 14. [. . . ] Each pair of colored lines on either side of the central distance scale index line corresponds to f/numbers of the same color on the aperture scale. To find the depth of field at a particular aperture, first focus the lens on the subject while looking through the viewfinder. Then check the numbers on the distance scale to determine the zone of focus for the aperture in use. The three photos shown clearly depict the changing depth of field; with the photo at the immediate right, the field is shallow at the f/4 setting, while the photo at the extreme right shows a depth of field extending from approximately 2. 7m (9 ft) to infinity (°°). EXPOSURE MEASUREMENT The exposure meter of the Nikon EL2 utilizes Nikon's through-the-lens center-weighted exposure measurement at full aperture. The meter reads the light over the entire focusing screen but favors the central 12mmdiameter area, while taking the entire area into consideration. This allows you to make precise readings of the selected subject area, and results in more balanced overall exposures. A u t o m a t i c Shutter Speed Selection When set to the " A " shutter-speed dial setting, the EL2 is capable of fully automatic selection of the shutter speed appropriate for the aperture setting of the lens and the existing lighting conditions. The exposure meter display, visible within the viewfield of the finder, enables the photographer to maintain continuous control over the exposure while viewing and focusing, and without the need of removing the eye from the viewfinder. And as lighting conditions (or the aperture setting) change, the shutter speed control circuit continues to maintain continuous and automatic control, for perfect exposure every time. To take a picture using automatic shutter speed selection, first set the shutter-speed dial to " A " (the green needle in the finder will move to the upper " A " position and remain) and select an appropriate aperture setting. As you compose and focus, the black needle will continuously indicate the shutter speed being selected for correct exposure. Prior to exposing the film, verify that the needle is indicating a shutter speed appropriate for the subject; if the indicated speed is too fast or too slow, simply adjust the aperture ring on the lens until the desired shutter speed is indicated. Then, press the shutter release button to expose the film. Note that as long as the needle remains within the scale, provided the EV range of the metering system is not exceeded, the camera provides the correct exposure automatically. ' ' , ' , "'--"* " «•?"

To determine the correct exposure using manual speed selection, perform the following: Switch on the meter in the usual way and adjust the shutter-speed dial until the green needle in the exposure meter display aligns with the desired speed; then, simply adjust the aperture setting of the lens until the black needle moves to overlap the green needle. If deliberate under- or overexposure is desired, adjust the controls so that the green needle is overlapping the next higher number (one-step underexposure) or the next lower number (one-step overexposure). Example under- and overexposure indications are shown on the following page. 0 TIP 500 60 c 5D0 250 iP 30 15 I < < 2 I 2 D Deliberate one-step underexposure I Exposure Control The amount of light reaching the film plane is determined by a combination of the lens aperture and the shutter speed. Since the two are interrelated, different combinations will give the same exposure. A 1-step change in the shutter speed, or a 1-stop change in the aperture setting, will either halve or double the exposure. For example, a shutter speed of 1/125 second passes twice as much light as a setting of 1/250 second, and only half as much light as a speed of 1/60 second; for an aperture setting of f/11, twice as much light as f/16, and half as much as f/8, is passed. [. . . ] Be sure to: Clean batteries periodically (wiping with a rough cloth will remove residues that might otherwise impede performance); install batteries properly, checking for proper polarity; remove batteries when not using the equipment for an extended period; change weak batteries promptly to prevent leakage within the camera; store unused batteries properly (in a cool, dry location) to maximize service life; dispose of batteries properly (do not burn); and keep out of the reach of children. For details regarding battery performance, refer to the original manufacturer. CHANGING THE LENS To remove the lens from the camera body, press the lens release button and, holding the button depressed, twist the lens clockwise as far as it will go. With this action, the lens will come loose and can be lifted out. To mount a lens fitted with a meter coupling ridge, perform the following: Check that the meter coupling lever is released (see "Coupling Lever Lock/Release Operation" on page 43 for details); position the lens in the camera's lens mounting flange so that the mounting indexes on the lens and camera body are aligned; and, then, twist the lens counterclockwise until it clicks and locks into place.
