I’m a nonprofessional UW shooter based in Virginia USA.  I’ve been at it for over 15-years though!  Thanks for the efforts to put together a new pixel forum.  I have lockout out of the other one for over 6-months. 

I recently upgraded to a nauticam housing for my Nikon Z6. I’m taking it diving for the first time later this week. I’m afraid of the learning curve after using a D90 in an ikelite housing for years, but I’m looking forward to the results. 

Great to have you with. Overton. Good luck with the Z6.  Not a word of difference I think, in principle, from your D90.

I love my D90!  Sadly I have never had the means to take it underwater.
