FS - Sea & Sea Dome Port 240 and Ring gear set for Canon EF 11-24mm F4L USM Lens

03 April 2018 - 03:48 PM

I'm selling a very lightly used Sea & Sea Dome Port 240 and Ring gear set for Canon EF 11-24mm F4L USM Lens. It's a great dome for a really wide lens - I'm only selling in order to have rent money by end of month.

This is the same dome port as the regular 240, however it has a larger rear opening to fit the 11-24mm lens. It fits all other wide-angle and fisheye lenses as well, making it very versatile. Sale comes with the Conversion Ring 25 that adapts the larger opening to all the regular Sea & Sea port extension rings, the zoom gear for the Canon 11-24mm lens, and S&S dome port cover.
Condition: Dome shows very light signs of wear (it has done about 8 dives). There are a few very minor scratches on the acrylic that do not appear in underwater images. But it's used, so this is the reason for the steep discount!
Retail Price:  $2,200
Selling Price:  $1,599   **A fantastic deal !!
Buyer pays shipping. Please DM or email with questions. Thanks.

DIY Underwater Video Tripod

Hey all,


I just put together a little video on making a tripod for my camera housing that rotates around the port - horizontal for traditional video and vertical for social media.  Figured I would share the details.

It's all about those successful DIY projects!
