If you change the shutter speed or aperture during movie shooting, the
changes in the exposure may be recorded.
Zooming the lens during movie shooting can cause changes in the
exposure regardless of whether the lens’ maximum aperture changes
or not. The changes in the exposure may be recorded as a result.
If you move the camera to the left or right quickly (high-speed panning)
or shoot a moving subject, the image may look distorted.
Flickering, horizontal stripes (noise), or irregular exposures can be
caused by fluorescent light, LED bulbs, or other light sources during
movie shooting. Also, changes in the exposure (brightness) or color
tone may be recorded. In the <a> mode, a slow shutter speed may
solve the problem.
Check if your finger is blocking the speaker (p.22).
