I bought this beautiful glass dome and lens combo new in June last year to shoot on a new Sea & Sea MDX-80D housing. A couple of months ago an old friend decided to quit u/w photography and gave me his fisheye lens and another glass port, and I don't need to own two sets of fisheye lenses, zoom gears, and ports.
The Optical Dome Port II sells for $1030 at Backscatter, and the Tokina 10-17mm f/3.5-4.5 fisheye for Canon sells for $469. The zoom gear costs $220. There's no point in separating them, so I'll sell them as a set only. I'm asking $860 plus insured shipping. That's half the retail cost, so please don't bother trying to haggle on this one. Below are links to a few of my shots taken with this dome and lens.
Thanks for looking. Please let me know if you have any questions.
