For a list of lenses and their recommended ports see:
SLR Port Charts on the Ikelite website.
For a general
discussion of lens ports and their applications, see the article
"Interchangeable
Lens Ports" on the info website. |
Considerations for Choosing a Lens Port:
|
Your lens may already be listed in the SLR Port Charts on the Ikelite website. |
Size restrictions: Maximum lens diameter is 84mm. If focus
or zoom clamp is required, maximum barrel diameter is 71mm with
the standard Ikelite clamp set, 76mm with the special clamp set
#5509.28.
Mechanical
restrictions: Lens couplings use a rotary action, therefore,
push-pull zoom controls cannot be used underwater. Manual focus
zoom lenses are not recommended.
 Optical Requirements:
In general, wide-angle and Zoom lenses should be used with a
dome port; standard, macro and telephoto lenses should be used
with a flat port.
Filters:
When a Zoom lens is used with a 6" dome port, a +4 Diopter
close-up lens
is required. A UV filter is not required underwater. An Underwater
Colour Correction filter is not required when using flash.
Vignetting:
With long-throw lenses, there is always a danger of vignetting
when the front of the lens is furthest back in the port. This
applies particularly to 1:1 Macro lenses. If the possibility
of vignetting at infinity is not acceptable, use a dome port. |
Lens Physical Length: Rotate the focus and zoom controls
until the lens is at its maximum length. Measure the length of
the lens, including any filters or diopters you intend to use,
and choose a port which can accommodate it.

Control Linkages: The Ikelite digital SLR (SLR-DC) housing
has provision for one rotary zoom or focus control. The
housing is supplied with a manual focus/zoom coupling (gear sleeve
and lens-barrel clamp) which works with most lenses. Since there
is only one mechanical coupling, it can be used for focus or
zoom, but not both; for which reason, manual focus zooms are
not recommended. Some longer lenses have a zoom or focus barrel
which lies beyond the reach of the housing mechanism. In this
case, a flat port with focus/zoom control is required. Since
the mechanical coupling is rotary, push-pull type zoom lenses
cannot be zoomed when inside the housing. |
|
When testing a lens with a port for the first time, lie
the housing on its back and put a few layers of tissue paper
over the front of the lens before winding it close to the port
window. Check that clearance is still sufficient with the port
pressed firmly into the housing (as it will be by water-pressure
while diving). Unsuitable ports can be returned for refund or
exchange, provided that they are complete with original packaging
and documentation, and undamaged. |
