Yes, I have. I have used it on both Full Frame (my Nikon D4) and on cropped (my Nikon D7100).
Here are some shots (including showing the addition of the Multiplier):

And comparison with the Subsee +5 on the D7100.

Be aware that this a very powerful lens, especially with the crop factor of the camera - and you will find far more subjects suited to less powerful (but still very powerful dioptres) like the Subsee +5 and +10.
I am planning a more detailed write up on this lens when I have time.
