Exposure Metering System 3D Matrix Metering Center-Weighted Metering Spot Metering DCS 315 no yes yes DCS 330 yes yes yes 3D Matrix Metering 6 3D Matrix Metering is only available with the DCS 330 camera. General This system is ideal for quick operation in any exposure mode. With D-type AF Nikkor lenses, 3D Matrix Metering is automatically activated. 3D Matrix Metering uses three types of data: (1) scene brightness, (2) scene contrast and (3) distance to focused subject (distance information). Data on scene brightness and contrast are detected by the camera's eight-segment Advanced Matrix Sensor, while data on the distance to focused subject is detected and relayed by the D-type AF Nikkor lens in use. Information sent by the camera's autofocus system indicating whether the main subject is centered is also considered in the computation. Through analyzing this data, your camera provides correct exposures even in extremely complex lighting situations. If a non-D-type AF Nikkor lens is used, Advanced Matrix Metering is performed. Although the lens does not provide distance information, the eight-digit Advanced Matrix Sensor provides a correct exposure in most lighting situations. 6-27 Center-Weighted Metering With approximately 65% of the meter's sensitivity concentrated on the 8. 4 mm-diameter circle in the viewfinder and approximately 35% outside this circle, this meter is useful when you want to base your exposure on a specific area in the scene. In Auto Exposure mode, to measure the brightness of the picture's off-center portion, use the AE-L button. Refer to "Using the Auto Exposure Lock Function" on page 7-4. Spot Metering Nearly 100% of the meter's sensitivity is concentrated on the 2. 5 mm-diameter circle (approximately 1% of entire frame) in the center of the viewfinder. Use this meter for extra-selective exposure control; experience is required to achieve optimum results. 6-28 Selecting the Metering System Press and hold the Metering button and rotate the Main-Command dial to set the desired Metering mode. Ps MDE FNC SET () +/- RESET BUSY The following indicators appear in the Camera Status LCD panel and viewfinder: F S ISO A PRINT TYPE 3D Matrix Metering (DCS 330 only) Center-Weighted Metering 6 General AF-S C F Spot Metering DCS 315 only - The 3D Matrix Metering icon may appear on the Camera Status LCD panel when you press the Metering button. However, you will not be able to set 3D Matrix Metering. Use the Main-Command dial to select either Center-Weighted or Spot Metering. 6-29 AF Mode and Focus Area Your camera features two Autofocus modes, Single Servo AF (AF-S) and Continuous Servo AF (AF-C). The autofocus system offers a choice of two focus areas, Wide ( [ ] ) and Spot ( o ). AF mode and focus area are set simultaneously. Refer to "Setting AF Mode and Focus Area" on page 6-32. AF-S Single Servo AF Lightly pressing the Shutter Release button activates the lens focus adjustment. Because the priority is on correct focus, the shutter will lock until a stationary subject is in focus (showing in the viewfinder) or until the camera anticipates a moving subject to be in focus. After focus is achieved with a stationary subject, the focus remains locked for as long as the Shutter Release button is lightly pressed. This feature proves especially useful when recomposing a picture with the main subject off-center (page 6-36). If the camerato-subject distance changes, however, you must refocus. AF-C Continuous Servo AF Under certain conditions, such as very fast action situations, you may want to capture an image even before focus is successfully achieved. As you lightly press the Shutter Release button, focus detection begins and the lens continues focusing for as long as you keep the button lightly pressed. Since the priority is on shutter release, you can capture an image regardless of focus status. 6-30 [] Wide Area AF The Wide-Area focus brackets delineate the focus detecting area in the viewfinder. [. . . ] Vari-Program Provides variable programs for specific picture-taking situations. Vignetting Progressively diminishes illumination on the imager from the center to the corners. There are two kinds of vignetting: natural vignetting caused by the lens, and vignetting caused by improper use of accessories such as lens hood or filter. D-6 Appendix E - Focal Length Conversion The imager in your camera has a smaller image area than 35mm film or Advanced Photo System film. Because of this difference in size, images obtained from a DCS 300 Series camera using lenses designed for Nikon film cameras will also differ in size. [. . . ]
