I just saw your post about the Nauticam/E-PL5. It's been 4 months since you asked, so maybe you've already found what you want.
If not, maybe I can help. I'm moving back to a (big and heavy) DSLR rig, and I'd like to sell my Nauticam setup. I have the housing, an E-PL5 body, 14-42mm zoom lens with Nauticam zoom gear, 60mm Oly macro lens, and 8mm Panasonic fisheye lens, along with a Nauticam macro port 65, and the Nauticam 4.33 dome port for the fisheye, and ULCS metal tray and handle.
I'd like to get 1/2 the original purchase price plus actual shipping cost. Purchase price was 4314 USD, so this is for sale for 2157 USD.
Everything is in good condition and has been properly maintained. Here's a link to recent shots; most were taken with the Nauticam E-PL5 setup: /www.flickr.com/photos/firststage/albums
Would this be of any interest?
