Aquatica Port Extension Ring 54.5mm/2.135" for all Bayonet Style Housings 48457
The Port Extension Ring from Aquatica can be used for extending the length of a port to accommodate a longer lens or one equipped with accessories such as tele converter, frequently the case with macro photographic configuration. It can also be used for positioning a dome port as closely possible to a wide angle lens’s optical center. The wider the lens, the more critical this positioning will become, especially for rectilinear type wide angle lenses covering a field of view of over 90°.
A sturdy, trouble free stainless steel locking mechanism ensures that your port is reliably locked to the extension ring and the latter being safely held in place by the housing’s own locking mechanism.
