Maintenance and Storage
After using the W-30 lens in water (especially salt water), rinse with fresh
tap water and dry with a soft non-abrasive cloth. The lens surface has an
anti-reflective coating. Wipe the surface of the lens gently with the soft
non-abrasive cloth to prevent debris buildup that can cause spotting and
deterioration of the coating.
Caution:
Do not attempt to dry the lens by exposing it to heat from a hair
dryer, radiator, etc. This will damage the lens.
Store the lens in a cool, dry place with the front and rear lens caps fitted.
Do not
store the lens attached to a housing port. Temperature changes
can make the lens hard to remove from the port and cause accidental
removal of the port.
Taking Photos with the Lens
1. After entering the water, check that all of the air has escaped from the gap
between the lens and the housing port, and that no air bubbles are present.
This step is important and can affect the camera’s ability to focus. If air
bubbles are present it may be necessary to remove and reinstall the lens
underwater.
2. Zoom the camera to its widest-angle setting. If vignetting occurs at this
setting (i.e. you can see the edges of the lens in the corners of the
picture), zoom the lens in slightly to eliminate.
3. Best photo results will occur under well-lit conditions. The built-in flash of
the camera will not supply sufficient light to obtain good results. When
using the lens in poorly lit areas, the use of an Ikelite DS Substrobe is
strongly recommended.
