Troubleshooting Guide
If you shoot a movie when [
Maximum: 25600
] is set with [
ISO speed
range
] and ISO speed is set to ISO 16000/20000/25600, the ISO
speed will switch to ISO12800 (during movie shooting with manual
exposure). Even if you switch back to still photo shooting, the ISO
speed will not revert to the original setting.
If you shoot a movie when 1. L (50) or 2. H1 (51200)/H2 (102400) is
set, the ISO speed setting will switch to 1. ISO 100 or 2. H (25600)
respectively (during movie shooting with manual exposure). Even if
you switch back to still photo shooting, the ISO speed will not revert to
the original setting.
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. 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 also be recorded. In the <
a
> mode, a slow shutter speed
may solve the problem.
The manually set ISO speed changes when switching to
movie shooting.
The exposure changes during movie shooting.
The subject looks distorted during movie shooting.
The image flickers or horizontal stripes appear during movie shooting.
