Måske bør du kigge i
http://en.wikipedia.org/wiki/Nikonos
Der står bl.a. om Nikonos:
Each new generation brought in improvements in ambient light metering,
flash circuitry, and shutter design. The various models all had rugged
construction, simple controls, and were waterproof to 160ft/50m. The
camera is made waterproof by a simple system of silicone o-rings at
all the crucial joints. What truly set the Nikonos apart from other
cameras were its dedicated underwater lenses; they were designed as
"water-contact" optics, and are not usable in air. To this day, no
underwater camera system can quite match the Nikonos lenses for
sharpness and saturation.
The Nikonos underwater lenses included: (angle of view)
U/W Nikkor 15mm f/2.8 (94 degrees)
U/W Nikkor 20mm f/2.8 (78 degrees)
U/W Nikkor 28mm f/3.5 (59 degrees)
Nikon also created two "normal" lenses for use above or below water,
which made the Nikonos useful for outdoor activities such as kayaking,
canoeing, or foul weather situations. These two lenses, the 35mm and
80mm, were also fully waterproof, but did not have the benefit of the
specialized water-contact optics. The 35mm Nikonos lens in particular
is often paired with extension tubes to create a macro photography rig
for use underwater. There were also a handful of compatible lenses
made for the Nikonos by other manufacturers.
have a nice day
