4.4. Selecting Shutter Speed
The APX-i2’s electronic shuttering system makes it possible to control the exposure
time within a frame regardless of the current frame rate. By using an exposure time that
is shorter than the frame time determined by the frame rate (i.e. 1/frame rate sec.), you
can capture events taking place at an extremely high speed as a still image without
blurring effect.
The shutter speed can be changed from the basic speed of 1/frame rate sec. up to
1/250,000 sec. (4 micro seconds) at an increment of 1/1,000 sec.
This section discusses how to select a shutter speed from the keypad.
1. Make sure the camera Is in the LIVE mode.
2. Use the SHUTTER buttons on the keypad to select a shutter speed. Press the UP
[
△
] button to have the shutter speed made higher, the DOWN [
▽
] button lower.

3. Make sure the shutter speed indication in the lower left corner of the video frame
changes as either of the SHUTTER buttons is pressed.
Note: See the Shutter Speed Table, Section 7.1.6.
