Tips
• The F value becomes close to F3.4 as the zoom
position changes from W to T even when you
open the aperture by setting the F value lower
than F3.4, such as F1.6.
• The range of focus, an important effect of the
aperture, is called the depth of field. The depth
of field gets shallower as the aperture is opened,
and deeper as the aperture is closed. Use the
aperture creatively to obtain the desired effect in
your photography.
• This is handy for making the background
blurred or sharp.

When [IRIS/EXPOSURE] is set to

brightness by adjusting the iris, gain and
shutter speed with the iris ring.
You can also manually preset one or two of
these parameters and adjust the remaining
parameter(s) with the iris ring.
