Canon HF S21 - Manual (Page 72)

NOTES
[Tv Shutter-Pri. AE]:
- On screen only the denominator is displayed - [Tv 250] indicates a
shutter speed of 1/250 second, etc.
- In i »■ I mode, when the frame rate is set to [QEl PF24] or
[E3 24F], the shutter speeds available will be the following: 1/6,
1/12, 1/24, 1/48, 1/60, 1/100, 1/250, 1/500, 1/1000 and 1/2000.
- When recording in dark surroundings, you can obtain a brighter
picture by using slow shutter speeds; however, image quality may not
be as good and autofocus may not work well.
- The image may flicker when recording with fast shutter speeds.
- Recording movies under fluorescent iights: If the screen starts to flicker,
select [Tv Shutter-Priority AE] and set the shutter speed to 1 /100.
[ Av Aperture-Priority AE]: The actual range of values available for selec­
tion will vary depending on the initial zoom position.
When setting a numeric value (aperture or shutter speed), the number
displayed will flash if the aperture value or shutter speed is not appropri­
ate for the recording conditions. In such case, select a different value.
During exposure lock, the aperture value/shutter speed cannot be
changed. Set the aperture value or shutter speed before manually
ad]usting the exposure.
This function can also be assigned to the custom key/dial (iXi 89).
