Olympus announced yesterday on their website the upcoming release of a dome port, extension ring, and zoom gear, to use the Zuiko 7-14mm F4 wideangle zoom lens underwater in the PT-E01 housing.  Olympus expects to release the port system in July, but no pricing info was given - however the dome is glass so it will not be a “budget” accessory.  According to Olympus they: “now offer a range of 4 underwater lens ports and 2 underwater extension rings to support professional underwater photography using its 6 “Designed for Digital” ZUIKO DIGITAL lenses.” Of special interest was a hint that they plan to offer a fisheye lens in the future.
