Need help please!
I am about to start with underwater photography, looking to buy the Nauticam housing for the D750 and learning all that I can before I buy anything and get into the water with it.
Given the big investment, I am aiming to soften the blow by using my existing Nikkor 20mm 2.8D to start with and eventually upgrade to a Sigma 15mm (I am also leaving macro port on hold for a bit).
I know the Sigma 15mm will work with an 8.5" dome, but since the Nikkor 20mm isn't one of the officially supported lenses by Nauticam housings, I haven't found any information of the 20mm working with this same port. I wanted to hear from people that have tested it out and to hear what they thought about it, if the images coming out are decent enough and know if a diopter is needed (if so, which one).
Any help and feedback will be greatly appreciated. So far dealers are sharing their "gut feelings" and it isn't overly convincing.
