Justin the options are none at the moment- I have been on the phone with Ikelite several times talking about a solution and the facts are this- Sony has a bigger market share so they are looking at a dome port for the likes of the Sony line that would let you use a internal wide angel lens with the dome port to get better images. They said it might work for the Canon but the Canon wide angel lens is to big to fit inside the dome port! That the latest also they said the more phone calls and emails they receive from Canon users will help in a timely solution....SO CALL AWAY
Ask for the design manager.

I'll call anyways, but what about this statement which is on ikes website under the HV10 housing:
Canon's WD-H37C Wide 0.7X Converter Lens can be used on the camera with this housing. Using this lens requires the original port be replaced with either the optional Ikelite Dome Port #9306.70 or Flat Port #9306.71. The Dome Port provides a wider angle of coverage, but has limited zoom and macro range. The Flat Port offers full zoom and full macro capabilities
granted it is a .7x and not a .55, but if the quality is there, id be interested in that setup.
as far as the HV20 goes ike has this to say:
Special ports are available for use with the Raynox HD-5050 Pro high definition wide-angle lens. Optional ports sold separately as dome port #9304 or flat lens port #9304.1. Raynox HD-5050 Pro lens not included. Lens not available for purchase through Ikelite.
I do have that lens for above water stuff, and the quality is pretty good (for a $90 lens), so im curious if that would work with the HV10?
