Ports for the Sony Type 4
Ports are, in addition to camera lenses, are the most important component in an underwater imaging system. Their optical quality, and the precision in their positioning are strategic to the success of a final image.
Aquatica has been manufacturing ports that have been used across the film and photography industry since its modest beginning in 1982, and with good reasons. Its commitment to supply its users with quality constructed ports, which delivers image and color accuracy, along with excellent sharpness and color transmission, has made Aquatica the prime choice of discerning image makers ever since.
There are two basic ports designs to consider in underwater photography, the hemispherical dome ports and flat lens ports. Since dome port maintain the original field of view of a lens, they are typically used with wide-angle and fisheye lenses, flat ports, on the other hand, will narrow the field of you of a lens and create more magnification, thus creating a benefit for close up and macro lenses. The Aquatica modular port system has a range of different dome ports sizes, ranging in diameter size from as small as 4” to as large as 9.25.” and flats ports to accommodate your specific macro needs.
Installing an Aquatica port is easy, the four points bayonet mount used, makes for a quick and safe replacement of lenses or port without any fuss. Security on current Aquatica housings being provided by a built in lock. The uses of various lenses will often require different optical configurations, the modular nature, of the long established Aquatica system, simplifies that task by providing the photographer with a range of port extensions that will either help them optimize the critical optical center of the lens to that of a dome port. Or accommodate longer barrel lenses in macro configuration.
Every Aquatica housing has a lens chart associated to it. This lens chart will help guide you in selecting the right component for extracting the maximum from your chosen lens.
In the event that the extension ring does not feature a built in locking mechanism, a locking collar (18469) is also available to lock extension ring to a port (the extension being already locked in place by the housing locking mechanism).
