5. Focus and record the movie. Same as steps 4 and 5 for Autoexposure Recording. Caution ISO speed cannot be expanded to L (equivalent to ISO 50) in movie recording. During movie recording, avoid changing the shutter speed, aperture value, or ISO speed, which may record changes in the exposure or create more noise at high ISO speeds. When recording a movie of a moving subject, a shutter speed of approx. 1/25 sec. to 1/125 sec. is recommended. The faster the shutter speed, the less smooth the subject's movement will look. If you change the shutter speed while recording under fluorescent or LED lighting, image flicker may be recorded. Note Exposure compensation with ISO Auto can be set in a range of ±3 stops. When ISO Auto is set, you can press the < > button to lock the ISO speed. After locking the ISO speed during movie recording, you can cancel it by pressing the < > button. (ISO speed lock is maintained until you press the < > button.) If you press the < > button and recompose the shot, you can see the exposure level difference on the exposure level indicator ( ) compared to when the < > button was pressed. 283
