D. Please note that the BigEye Lens was designed to work underwater
only. Therefore, the lens should only be installed underwater, while
letting water enter the gap between the macro lens and the housing lens
port. Make sure that there are no air bubbles trapped between the
BigEye Lens and the housing lens port before taking images.
E. During the beginning of your dive, your lens might become foggy as a
result of an increase in the air temperature inside the lens, following
submersion in cooler water. Storing the lens in a cool dry place when not
being used, such as a padded housing bag with a few silica gel packs
inside, and submerging it in cool water for 10 minutes prior to the dive,
will assist in preventing such condensation. However, even if your BigEye
Lens starts fogging up at the beginning of the dive due to temperature
differences, please note that continuing to dive with it for about 10
minutes will eventually dissolve the fog.
F. When taking photos with the BigEye Lens installed, set your camera
focus mode to “
Macro
”. Failing to do so will result in blurred images.
G. The BigEye Lens can be removed and installed repeatedly throughout the
course of the dive. Whenever removing the lens, set your camera focus to
the desired mode, if it is not “Macro”.
H. When removing the BigEye Lens from the housing, it can be conveniently
stored by attaching it to the EyeGrabber F46, which mounts on Fantasea
Flex Arms, thereby making it easily available for future use. For further

I. It is recommended to use an external strobe when the BigEye Lens is
mounted on the housing. The BigEye Lens blocks the camera internal
flash, resulting in underexposed or shaded images.
J. When using an external flash, there are a few techniques that should be
followed in order to avoid a lens flare, which is often encountered when
using dome ports of any kind due to the reflection of the sub or strobe:
