Here are a couple of shots taken with the LSD prime. Well worth a look if you want something to take out an ugly background.
Here are before and after shots, all taken with Nikon D7100 in a Nauticam housing, 105mm VR and the Retra Prime LSD

Nice shots!
Its a pretty sweet piece of gear, for sure its gonna beat my old tubberware box+wetsuit sleeve-snoot!
It would however be nice to see pictures at the same magnification and composition, as there is a big difference in the quality of those two aspects in the before and after shots..
