SIGMA FD-70N - Manual (Page 18)

Basic Shooting Techniques
• Practice handling the FD-70N on land.
o Getting familiar with the location and movement of all the
controls and how the changes in settings can affect your
image is an important part of the process. It is better to
learn the basics of the camera’s operation on land, rather
than when first underwater. It is faster to operate the
camera out of the housing and you will not have the limited
time frame as you would if you were underwater.
• Focusing and Shutter release control.
o Get used to operating this control on the camera in both
half depress, and full depress movements. You will
frequently depress the shutter release only half way to
activate the exposure meter and auto focus to preview the
shooting conditions and make setting changes. Once you
get the feel for operating the camera control directly, you
can then try it in the FD-70N, using the housing’s trigger
control in the same manner.
o It is highly recommended that a Diopter +4 be used with
the standard kit lens and Macro lenses to help with the
focusing and triggering of the housing
• Use the viewfinder eyepiece
o Compose and view exposure information display. It is very
important that you become familiar with the information
display in the viewfinder so you can make proper exposure
settings and know what other settings have been made. You
will use this often and it is good to become familiar with it
before attempting to read it underwater. Also practice
composing and focusing the camera by eye, before using it
underwater to get the feel for this operation as well.
