A Exposure Preview (Exposure Mode M Only) In exposure mode M, pressing the Pv button lets you preview how the current shutter speed, aperture, and ISO sensitivity settings affect exposure. Pv button D Ending Live View Live view ends automatically if the lens is removed. Live view may also end automatically to prevent damage to the camera's internal circuits; exit live view when the camera is not in use. Note that the temperature of the camera's internal circuits may rise and noise (bright spots, randomly-spaced bright pixels, or fog) may be displayed in the following instances (the camera may also become noticeably warm, but this does not indicate a malfunction): • The ambient temperature is high • Live view has been used for extended periods • The camera has been used in continuous release mode for extended periods If live view does not start when you press the a button, wait for the internal circuits to cool and then try again. x 174
