Coming to you pros with a question (which I also sent to nautucam and will post their answer if and when I get it):

I just found about this lens:

Nikon NIKKOR Z DX 16-50mm f/2.8 VR

It seems compact, sharp and low light and translating the aps-c to full frame would fit about the focal length of the likes of the FCP-1. It’s a little longer than the kit lens so would probably need some extension ring(s).

What do you think about its use with water corrected optics?

Is your question around whether it can be used with Nauticam wet optics? with a Nikon Z50?

A ”better” lens does not always yield better results than a cheaper one when you put it under water, behind domes or wet optics. The front element plays a role here and at what angle light from dome/wet lens hits the optics. So better check out what Nauticams tests say. The cheap 16-50 might be sharper for a particular set-up. I use the z24-50 for wwl1C and works very well.

Sorry, my post is lacking a lot of information. I have a z8 and an FCP-1.

The hope would be that it would sharper, and if sharper that one could use a smaller aperture and that the reach would be a little further.

But agree that this is not a straight forward question to answer. I’m probably looking at this in a too simplistic way ;-)

it is not as straightforward as better lens=better underwater. Do not own the FCP (would like to) but I think the z24-50 is what’s recommended.

Sorry guys my question actually doesn’t make sense at all. Just comes to show I still have lots to learn… I somehow assumed that you could mount a dx lens on a full frame and use in fx mode which is either not possible or would vignette heavily. Ryan from Nauticam (really appreciated how quickly he replied which I didn’t expect, especially on a weekend) wrote back with this :

There have been some cases where DX lenses will cover a bit more than the APS-C "DX" sensor size, but quite full frame, or will cover full frame over part of their zoom range, but I haven't been able to find any examples documenting this on 16-50 f/2.8.

On Nikon full frame Z bodies: When you mount a DX lens on a Z5, Z6, Z7, Zf, etc., the camera automatically switches to DX crop mode and there's no way to override it Digital Photography Review. This makes it difficult to even capture a full-sensor image showing the image circle falloff, since Nikon locks you into the crop. Some users have worked around this with "dumb" adapters that break the electronic communication Photography Life, but I couldn't find anyone who did this specifically with the new 16-50mm f/2.8.

Third party cameras can give us some clues about coverage beyond DX, because they don't force the switch to DX when mounted. I searched the RED user groups for some examples as well, but I couldn't find any.

On RED V-Raptor: The V-Raptor with the VV (Vista Vision) sensor is larger than full frame, so a DX lens would show significant vignetting. The S35 version of the V-Raptor has coverage for Super 35mm lenses ProVideo Coalition, and Super 35 is roughly similar to APS-C/DX, so the 16-50mm f/2.8 should cover S35 mode cleanly. But I couldn't find anyone who has tested or posted images of this specific combo.

What we know about the image circle behavior:Some DX lenses are known to cover more than their rated image circle, especially at longer focal lengths. The older Nikon 35mm f/1.8G DX, for example, nearly covers full frame. With zoom lenses, some DX zooms "zoom" the image circle as they get longer, covering more of the full frame area at the telephoto end Digital Photography Review. There's a good chance the 16-50mm f/2.8 would show heavy dark corners at 16mm on a full frame sensor but might be usable (with vignetting) at 50mm.
