MID 3 Manual Zoom Effect If power zooming during exposure is enabled using the Pentax function No.15 selection 1 (See page 105.), the focal length can be changed with the power zoom ring during exposure. Interesting images can be created by adjusting the zooming speed and timing manually. * To create manual zoom effects, set the auto zoom switch to IP] (as for the ordinary power zoom function). For some lenses, set the auto zoom switch to [PZ]. NOLLYted0 03ONVA0V 3. Depress the shutter release button fully. The lens zooms according to the selected shutter speed, creating a dynamic zoom effect. * A fast shutter speed reduces the zooming time and almost no zoom effect is obtained. For instance, a 28-105mm zoom lens takes about 1 second to zoom from the 28mm position to the 105mm position. That is, a shutter speed of at least 2 seconds is required for a full zoom effect to be produced. If the shutter speed is too slow, the shutter remains open after zooming has been finished, creating two images of one subject in two different sizes on a single frame. * If the zooming range is too large, the image becomes difficult to see due to excessively increased blur. * Use of a tripod is recommended to prevent camera shake.

Effect
If
power
zooming
during
exposure
is
enabled
using
the
Pentax
function
No.15
selection
1
(See
page
105.),
the
focal
length
can
be
changed
with
the
power
zoom
ring
during
exposure.
Interesting
images
can
be
created
by
adjusting
the
zooming
speed
and
timing
manually.
*
To
create
manual
zoom
effects,
set
the
auto
zoom
switch
to
IP]
(as
for
the
ordinary
power
zoom
func-
tion).
For

set
the

3.
Depress
the
shutter
release
button
fully.
The
lens
zooms
according
to
the
selected
shutter
speed,
cre-
ating
a
dynamic
zoom
effect.
*
A
fast
shutter
speed
reduces
the
zooming
time
and
almost
no
zoom
effect
is
obtained.
For
instance,
a
28-105mm
zoom
lens
takes
about
1
second
to
zoom
from
the
28mm
position
to
the
105mm
position.
That
is,
a
shutter
speed
of
at
least
2
seconds
is
re-
quired
for
a
full
zoom
effect
to
be
produced.
If
the
shutter
speed
is
too
slow,
the
shutter
remains
open
after
zooming
has
been
finished,
creating
two
images
of
one
subject
in
two
different
sizes
on
a
single
frame.
*
If
the
zooming
range
is
too
large,
the
image
becomes
difficult
to
see
due
to
excessively
increased
blur.
*
Use
of
a
tripod
is
recommended
to
prevent
camera
shake.
