brightness by opening and closing the lens mechanically.
How to set/operate

2. Press the IRIS button to display the iris setting.
3. Adjust the iris setting using the iris ring.
Note: A lower iris setting opens the lens and increases the

Note: Auto control requires an E-Mount lens or an A-Mount lens
with LA-E2+A mount adaptor.
To engage auto control permanently, press the IRIS button
again.

Shutter speed

The shutter speed can also be used to control the quantity of
transmitted light.
In still photography, both the shutter speed and the aperture
(iris) are used to control the light volume. With video cameras,
however, shutter speed is more problematic. Faster shutter
speeds can cause subject movements to appear brittle and
unnatural, while slower shutter speeds can make movements
and camera panning appear jerky.
How to set/operate
1. Set the AUTO/MANUAL switch to MANUAL.
2. Press the SHUTTER SPEED button to highlight the shutter
speed setting.
3. Adjust the shutter speed using the SEL/PUSH EXEC dial.
Note: A shutter speed of 1/100 sec is displayed as 100. Thus a
higher value indicates a faster shutter speed.
