I have Nikon D500 in Nauticam housing. I already have the 4.33" and 8.5" domes along with 20mm and 40mm port extensions. Currently using the Tokina 10-17mm.
I would like to try out some astrophotography and have considered the Tokina 11-16mm f2.8 as a start. From this forum I can see that this lens has positive reviews for underwater use and I could use my existing 8.5" port. The nauticam chart recommends a 50mm extension - could I combine the 20 and 40 as a 60 and achieve same results?
When I was back in Australia last week I visited a camera dealer and they recommended the 11-20mm f2.8 instead. I was hoping to get something I could use topside and underwater but have not been able to find too much information on the 11-20mm for underwater use.
Any opinions on which would be better? I did notice that the N120 port chart from nauticam does not specify zoom gears for the 11-20mm or would the 11-16 still work?
