Nope. In fact, I see very little reference to it in UW photo chatter.
The 2.8 is the macro one, right?
Just FYI, I am contemplating buying a Nikon camera kit and have narrowed down my lens choices, but I haven't bought anything Nikon yet. I am waiting to see what new higher-end cameras (Z8ii, Z7iii, and Z90) come out in the next few months before I decide what to buy.
I have been doing a lot of research on the Nikon kit over the past many months and getting myself educated on the subject. I checked all of the Nauticam port and lens charts for Nikon. I, of course, follow you on INTG and FB very closely
I have narrowed the lens choices to: Z105mm macro, Z50mm f/2.8 Macro, Z24-50mm (your favorite), Z14-30mm, and possibly the newest version of the wicked expensive Z24-70mm lens.
I would suggest a good first UW lens selection would be the z105, z25-50 w/WWL-C, and the F-mount 8-15mm FE w/140mm dome. A 50 or 60mm lens is nice to have (for me) but might be essential for Black Water, which I have not done yet. You can use a single flat port60 with a 20mm extension for both the 60 & 105 lens.
I have the F-mount 60mm which I occasionally use for macro combined with a Kraken KRL-09 wet wide flip lens.
The other lens I have but don't use underwater anymore are the F16-35 and 8" Nauticam dome port.
As for new Nikon bodies, I guess they will always be in the pipeline but I don't see a deficiency with the current lineup. Between the Z8 and Z6III I think you have excellent options. The Z8 has seen major firmware updates periodically that added significant and useful features. It is really nice to see meaningful upgrades with free software updates without having to buy new hardware. Nikon is pricing much lower than Sony as well for similar tier hardware.
