After much anticipation, Ikelite has released photos and details about their new 8” dome port for SLR housings.  Ikelite has also published an updated port chart, showing lens compatibility with the big dome, as well as a listing of which lenses Ikelite believes perform better behind the 8” dome as opposed to the standard 6” port.  Another feature requested by users and now implemented by Ikelite is the use of an extension ring system (Ikelite calls them stalks) so that one 8” dome with various stalks can be used with a variety of lenses.
