Problems and Solutions
●
Smudges appear in photographs:
•
Are there smudges on the front or rear (mount-side) lens elements?
•
Is there foreign matter on the image sensor? Perform image sensor
cleaning.
●
Bokeh is irregular:
With fast shutter speeds and/or fast lenses, you may notice
irregularities in how bokeh is shaped. The effect can be mitigated by
choosing slower shutter speeds and/or higher f-numbers.
●
Shooting ends unexpectedly or does not start:
•
Shooting may end automatically to prevent the camera
overheating, for example if:
- The ambient temperature is high
- The camera has been used for extended periods to record movies
- The camera has been used in continuous release modes for
extended periods
•
If photographs cannot be taken because the camera is running hot,
turn the camera off and wait for it to cool before trying to take
photographs again. Note that the camera may feel warm to the
touch, but this does not indicate a malfunction.
