Using the Eyepiece Cover Even if the drive mode is set to continuous shooting, only one shot can be taken. You can also use the self-timer or bulb timer with mirror lockup. If 30 seconds elapse after the mirror has locked up, it will go back down automatically. Pressing the shutter button completely locks up the mirror again. For mirror lockup, using a tripod and Remote Switch RS-80N3 (sold separately) or Timer Remote Controller TC-80N3 (sold separately) is recommended (p.248). You can also use a remote controller (sold separately, p.248). Setting the remote controller to a 2-sec. delay is recommended. Using the Eyepiece Cover When you use the self-timer, bulb, or a remote switch and do not look through the viewfinder, stray light entering the viewfinder can cause the picture to look dark. To prevent this, use the eyepiece cover (p.33) attached to the camera strap. During Live View shooting and movie shooting, attaching the eyepiece cover is unnecessary. 1 Detach the eyecup. While grasping both sides of the eyecup, slide it upward to detach it. 2 Attach the eyepiece cover. Slide the eyepiece cover down into the eyepiece groove to attach it. X After you finish shooting, detach the eyepiece cover and attach the eyecup. 247
