18429
Low profile Macro port for use with Canon 60mm EF-S and Tokina
35mm AT-X M35 PRO DX macro lenses. For all bayonet housings.
A low profile flat port, this version of our modular flat
port system has a shorter, much smaller length than the other
flat ports and was designed to take full advantage of the much
more compact macro lenses available from some manufacturers.
The port can also be combined with a variety of extension rings
to accommodate longer lenses, including lenses with close up
lenses, teleconverters or extension tubes.
The flat lens is made of BK-7 material, finely polished and
coated with a superior Silicon Oxide coating (SiO2)
on the external surface. This coating is not only a more resistant
type of coating but has a 0.01% reflective index, improving
light transmission. Additionally this SiO2 coating is
a perfect match to the index of water, which naturally reduces
reflections.
The main difference of this port from
the AF/MF port, aside from being lighter and narrower, is
that it doesn’t have
the side mounted knob that can be connected to a focus gear.
Since it is dedicated to compact macro lenses, in most the
manual focusing can be accessed via a gear connected to the
left hand focus/zoom control knob of the housing, like its
bigger sibling the 18428, this low profile flat port is designed
for general purpose macro work, and it should fulfill all the
needs of the dedicated photographer.
For a list of the available extension and
their dimension please visit the extensions
rings section. A lens chart associated with
your camera housing will inform you of the most current popular
combination.
