Remote Control Shooting F Remote Switch RS-60E3 (Sold Separately) Remote Switch RS-60E3 (sold separately) comes with an approx. 60 cm/2.0 ft cord. When connected to the camera's remote control terminal, it can be pressed halfway and completely, just like the shutter button. Using the Eyepiece Cover When you use the self-timer, bulb, or Remote Switch and do not look through the viewfinder, stray light entering the viewfinder can cause the image to look dark. To prevent this, use the eyepiece cover (p.27) attached to the camera strap. During Live View shooting and movie shooting, attaching the eyepiece cover is unnecessary. 1 Remove the eyecup. Push the bottom of the eyecup to remove. 2 Attach the eyepiece cover. Slide the eyepiece cover down into the eyepiece groove to attach it. After taking the picture, detach the eyepiece cover and attach the eyecup by sliding it down the eyepiece groove. 304
