I am using the Tokina 12-24 in the AD7000 housing, with 8" dome and what I thought was the correct extension ring (28.5 mm #18453) and get a halo in my shots when shooting below ~15mm. Checked the camera/lens and definitely only occurs in the housing. Do I need a different extension ring? Am I doing something wrong? Any tips/help would be appreciated. Thanks!
Had awesome conditions yesterday on the STOLT DAGALI (130 fsw), with 30-40 feet of visibility with plenty of ambient light and 43 degrees on the wreck. Finally got some quality time in with my D7000 in Aquatica housing. Shot some video too but that will probably take a while to edit since it's new territory for me.
