SENSOR AND LENS
11.6 million pixel 4K Exmor HD CMOS sensor
The NEX-FS700R features a large image sensor that produces powerful “bokeh” effects and brings subjects to life while providing
excellent sensitivity for clear images with minimal noise in low-light settings in both standard and Full HD 10 x super slow motion
modes.
At a given angle of field, a larger sensor with a longer focal
length will create more background blurring. When depth of
field is relatively shallow, this accentuates the region that is
in focus and creates a striking sense of presence.
The larger the sensor, the greater the area available for
capturing light. More light in turn boosts the sensitivity and
the signal-to-noise ratio, allowing the camera to produce
clear images with minimal noise even at maximum gain in
low-light settings.

About depth of field
To capture the entire view from foreground to background in focus, photographers typically use a wide-angle lens with short
focal length together with a narrow aperture, and try to get a reasonable distance from the main subject.
Conversely, to accentuate the subject by blurring the background or surrounding scenery, a telephoto lens with longer focal
length is used in combination with a wide aperture, and the camera is brought closer to the subject.
In theory, depth of field is governed by three factors: f-stop (aperture), focal length and distance from the subject. In practice,
however, the distance between the subject and the background also influences the amount of blurring.
