ELECTRONIC SHUTTER
This product is not equipped with a mechanical shutter mechanism. It
provides an electronic shutter that electronically controls the image sensor
to adjust the exposure time.
The electronic shutter enables the high-speed shutter speed and
high-speed continuous shooting with no noise or vibration. However, the
electronic shutter has disadvantages, so be sure to note the following
points.
 Uneven exposure can easily occur under a flickering light source such as
a fluorescent light, so use the slower shutter speed.
 The flash tuning speed is set to 1/30 sec. or less (1/15 sec. or less when
the image quality is set to DNG and DNG + JPEG and the memory bit
count is 14 bits). When shooting with the flash using manual exposure,
set the shutter speed to 1/30 sec. or less (1/15 sec. or less).
 When shooting a fast-moving subject, distortion may occur.
