With Manual Exposure When manual exposure is selected, the manually selected shutter speed is lit and the metered speed flashes. 60 500 Flashes Lights You can rotate the shutter speed dial and/or the aperture ring on the lens to match the metered value, at which point only one shutter speed will be displayed in the viewfinder. Or you can disregard the meter reading and do your own exposure adjustments. With Automatic Exposure When AE is selected, the metered shutter speed is lit. If you are using exposure compensation, the shutter speed flashes to indicate that it is a compensated value. Locking the Exposure Setting (AE-lock) You can lock the exposure setting at the metered value using the AE-lock button. This is useful, for example, when you create a single panoramic picture from a series of images, to make sure they all have the same level of exposure. To lock the exposure setting, point to the subject when using the AE mode and press the AE-lock button. The exposure setting remains locked until the AE-lock button is released. 60 Lights or flashes 24 Taking Photos
