Recording Movies B Note on Recording Images and Saving Movies The indicator showing the number of exposures remaining or the indicator showing the maximum movie length flashes while images are being recorded or while a movie is being saved. Do not open the battery-chamber/memory card slot cover or remove the battery or memory card while an indicator is flashing. Doing this could result in loss of data, or in damage to the camera or the memory card. B Recording Movies • Memory cards with an SD Speed Class rating of 6 or faster are recommended when recording movies (A21). Movie recording may stop unexpectedly when memory cards with a lower Speed Class ratings are used. • When recording movies with N HD 720p (1280×720) selected for Movie options, the angle of view (the area captured in the recorded movie) is smaller than when taking still pictures. • You cannot change the optical zoom ratio once movie recording has started. • While recording movies, you can operate the digital zoom by using the zoom control. The digital zoom can magnify the image up to 4× the maximum optical zoom ratio. • Digital zoom degrades image quality. When recording ends, digital zoom is disabled. • In some cases, movie recordings may capture the sounds of the camera itself, such as those made by the zoom control, autofocus, vibration reduction, or aperture control when the brightness changes. • Smear (F3) visible in the monitor with movie recording will be recorded with movies. Avoiding bright objects such as the sun, reflections of the sun, and electric lights when recording movies is recommended. • When recording or playing back movies, colored stripes (interference patterns or moiré) may appear on subjects that have a regular, repeating grid, such as pattern of weave in cloths or windows in a building, depending on the shooting distance or zoom ratio. This phenomenon occurs when the subject's pattern interferes with the camera sensor grid, and it does not indicate a malfunction. B Notes About Autofocus for Movie Recording • When A Single AF (default setting) is selected for Movie AF mode, focus is locked by pressing the b (e movie-record) button to start recording (A85). • Autofocus may not perform as expected (A31). Should this occur, try the following: 1. Set Movie AF mode to A Single AF (default setting) before starting movie recording. 2. Frame a different subject (positioned at the same distance from the camera as the intended subject) in the center of the frame, press the b (e movie-record) button to start recording, and then modify the composition. 83 Recording and Playing Back Movies
