We have received some information from Aquatica about their 8” dome port for Ikelite housings. The port uses the standard 8” Aquatica acrylic dome, with an aluminum back plate and integral ikelite port adapter (meaning it’s all one piece). Aquatica has dunk tested the port and confirms that it works well with the Nikon D70 housing and 10.5mm fisheye lens. According to Blake Stoughton, a principal at Aquatica, they intend to release a series of extension rings so that this port can be used with a variety of Canon and Nikon lenses. The cost should be competitive with other offerings.
