Back Button Focus
Back button focus takes some adjustment to get used to but can be
very valuable in a variety of shooting scenarios. To set up your camera
for back button focus, set the
to "mode3."
The AEL/AFL button is conveniently accessed by a thumb lever on the
side of the housing. Instead of half-pressing the shutter to obtain focus
and lock focus, press the AEL/AFL button.
For super macro photography, you can use this technique instead of
a manual focus gear. Press and hold AEL/AFL to lock focus at the
minimum focusing distance of your lens. Then move slightly in or out
until the subject is in focus.
Setting Up Your Housing
Opening the Housing
1. Push the lid snap lock forward and lift the curved end away from
the housing.
2. Lid snaps are designed to provide enough force to compress the
o-ring for a proper seal. Keep firm pressure against the lid snap
while lifting it away.
3. Repeat with opposite lid snap.
4. Remove the housing back.
