Hi
If you have a Nikkor 16-80 mm DX f/2.8-4 VR and both DX, FX cameras, please mount it on your FX to see what vignetting level at  16, 25, 35, 50 and 80 mm focal length on a F frame, 1.2 crop  and 1.5 crop  setting. Reviews praise this Nikkor  16-80 mm (light, sharp and expensive)  having better images on a DX camera like D500, D7200 than a 24-120 mm on a D750. I wonder if we can use it on a FX like D750 at 1.2 crop ( for street photography to ease our necks ).
Thanks

On the D750 - Shooting Menu / Image Area / Auto DX. Will allow the camera to recognize DX lenses and automatically adjust.

And I understand that once it auto detects DX and goes into crop mode, you should have no vignette, just as if you were using it on a DX.

The vignetting should happen only if you use the FX camera in FX mode with the DX lens.

I have a D7200 and this lens, I'm very happy with it, but no FX camera to try it for you.

It is a mystery to me why folks can't think beyond "Auto DX" to accomplish what you are asking. I have neither this lens nor a D750, but have done exactly the same experiment with other DX lenses on my D850. (I looked at the 16-80, but it is f/4 over almost all of its zoom range, so I thought it was just too expensive, both new and used, at least at the time. Maximum aperture goes to f/4 somewhere around 25mm or so.)

In my experimentation, I discovered a couple of general trends. First, lesser grade Nikkor lenses (like the 18-200mm zoom) generally have a little bit larger image circles than higher grade ones (like the 17-55mm f/2,8). Second, the higher grade lenses generally have a sharper cutoff at the edge of the image, while lenses like the 18-200 fade off more gradually.

When I use a DX lens on my D850, I use an image format that is not available on the D750...24x24mm square format. It will work with every DX lens and provides an image with about 50% more pixels than DX (24/16). I'm not sure why that format is not provided on the D750.

My guess is that it's about 50/50 whether there will be visible vignetting with that lens at a 1.2 crop. But I also think that there is a really good chance that even if there is a little bit of vignetting, a tiny bit of cropping of the ends of your image will get rid of it.

Yes, my Nikon DX lenses 70-300 AF-P, 16-55, 55-200, 12-28 (Tokina) work well on my D750 at 1.2 crop, even at F frame in some focal lengths. I would like to get this 16-80 mm on my D750 ( at 1.2 crop) ( the DX crop is a waste of using my D750) for street photography instead of a 24-120 mm f/4 (too heavy for a 70 Y.O. on a day walking). So far still waiting for the right answer. Thanks

I put the 16mm-80mm on my D750 without the lens hood (which is quite large) and am seeing vignetting at all of the settings, in FX mode, DX mode, and 1.2. It's worse at 16mm and gets progressively better at 80mm, but vignetting is still noticeable.

Does the D750 have "blackout" viewfinder masks when the non-FX formats are selected? It may be necessary to snap an exposure at a couple of focal lengths to see for sure whether the vignetting is in the image area.

Here are some images, shot at 1.2, at focal lengths of 16, 35, and 80. These are straight out of the camera, but it looks like vignetting is very limited at 80mm and pretty manageable at 35mm.

Same experience for me with my 16-80 mm DX on my full frame D800. Vignetting is apparent in the viewfinder, but well outside of the DX frame lines. To my imperfect 75 year old eyes, no vignetting in the saved image when you let the camera choose Auto DX.

Thanks.
It is quite clear that this 16-80 mm f/2.8-4 cannot be used on D750 at 1.2 crop.
So I stick with my legacy Nikkor 28-85 mm f/3.5-4.5 AF. The 24-120 mm f/4 is heavy for me.

Thanks you all

If the kit is heavy for all day, how about the 16-80 with a D5600 body - very light weight outfit. The D5600 is a 24mp sensor and yields fine quality.

I have a
D5300 and ithe 16-80 works very well especially for wider angle landscapes.

"...So I stick with my legacy Nikkor 28-85 mm f/3.5-4.5 AF. The 24-120 mm f/4 is heavy for me..." trinhqthuan I shoot and love the epic vintage Nikon 28-105mm f/3.5-4.5 AF-D on my FX bodies... it's ~ 60 grams lighter than your 28-85 mm f/3.5-4.5 AF Nikkor... And it as virtually no distortion... Also being a "D" variant I can use speedlights effectively in iTTL with it. The 28-105mm macro mode while a little kludgy is better also.. I looked for the 28-85mm but all the samples I tried where not at the same level of acuity as the 28-105mm.

FYI: My Tokina AF 11-16mm f/2.8 AT-X Pro does not vignette on my FX cameras at f/16 thru f/15... However that puppy weighes 560 grams which is 50 grams more than your 28-85 mm f/3.5-4.5 AF Nikkor... Weight unfortunately is the price you pay for fast glass and the reason the PF Nikkors are in constant back order as the gerontology crowd matures and can no longer shoulder fast glass...

How this helps...
All the best on your journey trinhqthuan
