6.4 The electronic trigger cable is not actuating the
camera shutter
There are a few common reasons why the electronic trigger cable might not be actuating
the camera shutter.
1.
Ensure that the electronic trigger cable is connected to the camera body and to the
EPIC Pro on the left of the LCD display.
2.
Verify that a memory card has been inserted into the camera and that it is not full.
3.
Verify that the camera is powered and that there is sufficient charge on the EPIC Pro
battery to complete a panorama. (See Chapter 2.2 for checking battery status.)
4.
If you plan on using manual focus, verify that the lens is in the manual focus mode.
5.
If you plan on using auto focus, ensure that you are able to achieve focus by pressing
the shutter button half way to engage the auto focus sub system. (See Chapter 2.8 for
more information on auto focus)
6.5 The electronic trigger cable is not allowing the camera
to autofocus
1.
Navigate to 'Options' > 'Expert Options' > 'Shutter Length' in the EPIC Pro Menu.
Increase the value of the 'Shutter Length' setting to a value greater than 'Time per Pic'
to give your auto focus sub system longer to achieve good focus.
2.
If you have a faster lens (lower minimum aperture value such as f/2.8) consider using
this lens. Note that a zoom lens will normally have two values printed on the lens. A
minimum effective aperture at the shortest focal length and then a slower effective
aperture at the longest focal length.
3.
Check the servo mode or release policy of the servo mode. Different camera manu-
facturers use different terms for the servo modes. Typically a single servo mode
uses a focus policy where the camera will not actuate the shutter unless the auto
focus system communicates that a good focus was achieved. On some cameras you
can change the default focus policy to a release policy where the photograph will be
captured regardless of whether the camera achieves good focus. Continuous servo
modes typically have a default policy of release where the trigger will be actuated re-
gardless of the whether the camera achieved a good focus. Release policy can cause
more problems than it solves depending upon your equipment and the subject you are
photographing.
4.
Consider using manual focus or a mixed manual focus and auto focus approach with
areas such as sky, water, plain walls that do not contain detailed features.
