Select [ON] for access to a range of slower shutter speeds in modes S and M.
- When [OFF] is selected, the minimum shutter speed varies with frame rate as follows.
- 120p: 1/125 s
- 100p: 1/100 s
- 60p: 1/60 s
- 50p: 1/50 s
- 30p: 1/30 s
- 25p: 1/25 s
- 24p: 1/25 s
- When [ON] is selected, the minimum shutter speeds for frame rates of 60p to 24p drop to 1/4 s. Those for 120p or 100p, or slow-motion videos do not change.
- Selecting [ON] and choosing a slow shutter speed helps prevent ISO sensitivity rising too high during shots of the night sky and other dark subjects.
- Videos recorded at slow shutter speeds when [ON] is selected will include repeated multiple copies of the same frames.
- To reduce blur caused by camera shake in videos recorded at slow shutter speeds while [ON] is selected, we recommend mounting the camera on a tripod.
