Precautions When Taking Pictures
Input Focal Length
When the camera is turned on with the adapte r and a K-mount lens
attached, the [Input Focal Length] screen appears. Enter the focal
length
of
the lens being used. (Enter "50" when using a 50mm F1.4
lens.)
Focusing
The focus mode is fixed to MF (Manual focus) when using the
adapter.
Use [MF Assist] in [Focus Settings] of the
[0
Rec. Mod e
1]
menu
to magnify the image in the center
of
the monitor. Refer to the
operating
manual
of
the camera for details.
[Focus Peaking] is added to [Focus Settings] by updating thefirmware. Focus Peaking emphasizes the outlines
of
the images
displayed
on
the monitor, making it easier to check the focusing
conditions.
Setting the Aperture Value
The aperture value can be set with either the lens
or
adapter,
depending on the K-mount lens being used.

Example: The aperture value is equivalent to F5.6 when a F1.4 lens
is
attached and
the
scale
on
the adapter
is
set to "4".
@ When the aperture ring is set to a-position other than
A,
or
using
a lens with
an
aperture ring that does
not
have an A position
Set
the aperture ring on the
adapter to [L] and adjust the
aperture value with the aperture
ring on the lens.
• If the aperture is closed more than necessary, a small aperture
blur (diffraction) occurs and causes your images to lose their
sharpness. Furthermore, incident light may be partially blocked
by
the shutter blades, and this may cause a gradual decrease
in
light intensity towards the image periphery. It depends on the lens
and subject, but
in
general, many lenses provide the sharpest
image at aperture around
FB
to F11.
Using a Tripod
Use the optional PENTAX Tripod Mount for DA*300mm
in
cases
where camera shake
may
occur.
With the lock screw loosened,
insert the tripod mount as
shown
in
the illustration.
Then, tighten the lock screw
to firmly secure into place.
• Do not use the tripod socket on the camera body as doing so will
place extra strain on the camera.
