I want to give a kudos to Ikelite for listening their customer needs. Just recently I check their new products showed on the DEMA '07 and got surprise to see they finally made a flat port system based on extension rings that actually uses the 8" dome bodies. This is great news for all Ikelite customers, who for years wonder how to go beyond 1:1 with the existing ports.
Now I'm just waiting the D300 housing and hope that they placed a 1" ball on top for focus lights... and maybe some other little issues....
Again Kudos to Ikelite.
