79Recording and Playing Back MoviesB Notes About Saving DataAfter taking a picture or recording a movie, the number of exposures remaining or the remainingrecording time flashes while images or movies are being saved. Do not open the battery-chamber/memory card slot cover while images or movies are being saved. Image and movie datacould be lost and the camera or memory card could be damaged.B Notes About Movie Recording• Memory cards with an SD Speed Class rating of 6 or faster are recommended when recordingmovies (A 15). Movie recording may stop unexpectedly when memory cards with a lower SpeedClass rating are used.• The optical zoom magnification ratio cannot be changed once recording starts.• Use the zoom control to operate digital zoom while recording movies. The zoom range isbetween the optical zoom magnification ratio before recording a movie and up to 4×.• There may be some degradation in image quality when digital zoom is used. When recordingends, digital zoom turns off.• The sounds of zoom control operation, autofocus lens drive movement (L26 only), and apertureoperation when brightness changes may be recorded.• Smear (F3) visible in the monitor with movie recording will be recorded with movies. Avoidingbright objects such as the sun, reflections of the sun, and electric lights is recommended.• Depending on the distance to the subject or the amount of zoom applied, subjects with repeatingpatterns (fabrics, lattice windows, etc.) may have colored stripes (interference patterns, moire, etc.)in them during movie recording and playback. This occurs when the pattern in the subject and thelayout of the image sensor interfere with each other; it is not a malfunction.B Camera TemperatureThe camera may become warm when shooting movies for an extended period of time or when thecamera is used in a hot area.B Notes About AutofocusAutofocus may not perform as expected (A 28). Should this occur, try the following:1. Set Autofocus mode in the movie menu to A Single AF (default setting) before startingmovie recording (L26 only; A 81, E39).2. Frame another subject—positioned at the same distance from the camera as the intendedsubject—in the center of the frame, press the b (e movie-record) button to start recording, andthen modify the composition.
