The answer is YES. I am surprised that you are asking this since I know you are an experienced shooter.
By the way, the DX format when used with a DX lens is also FULL FRAME since the whole sensor is been used.

I've been taking pictures of squirrels out my den window. Those guys can be very quick. I learned that if I zoom in too much, I put more pixels on them, but they are impossible to track, to keep in the frame, so now I back off some. Using DX instead of FX would have the same issues.

Yes you do, but it’s a gimmick as it’s no different than cropping later ... so you do get a 105-300 field of view but lose many millions of pixels.

You raise an interesting point that I am trying to get my head around. I am considering buying a new camera. Currently. I have a Nikon D7100 DX and am considering either the DX D500 or FX D850. Initially I was drawn to the D850 for among other reasons the 45+ mp sensor. But from what you have suggested I now believe the actual the pixel density across the smaller DX sensor image of the D500 will be a bit higher than the pixel density across the larger D850 image. So keeping all other factors the same, does the D500 provide equal or perhaps greater resolution?

From a resolution standpoint, the D850 is the clear winner. From a pixel density standpoint, they are similar (pixels per square millimeter of sensor area) with a slight edge to the D500, but the D850 will still have a higher native resolution. If you plan to shoot in DX mode all the time on a D850, then perhaps a D500 is a better bet, but why would you buy FX to shoot only in DX anyway?
If pixel density is what you are going for, the D7200 would beat both of the other 2 and at a fraction of the price.

So, on a Nikon D850 with a full frame 70-200 lens, if I put it the camera into Dx mode, do I get the 1.5% crop factor on the lens? So the 70-200 becomes a 105-300?


No. You are just cropping your picture in camera. No affect on the lens.

The FL remains unchanged (it is set by the lens design and has nothing to do with the camera), but you get FOV equivalent to a lens with 1.5xFL, provided same camera-to-subject distance.

By that logic, EVERY camera is a full frame camera. Full Frame is industry terminology for a sensor the same size as 35mm film. You can make up your own definition, but nobody will understand what you are talking about.

What you are doing is making your full frame camera into a crop frame sensor. Why buy the full frame in the first place if you are only going to use a DX size portion of your sensor?

Geesus. Now I understand what The Temptations meant when they sang "Ball of Confusion". Maybe that should be the name of this site.

Absolutely nothing happens. You just are not recording out to the edges of the image the lens produces. There is no miracle or free lens here. Exact same photo as if you cropped, or cut off, some of the photo on all four sides. It's all smoke and mirrors!

150% not 1.5%.

I never use the in camera crop on any of my cameras as it forces one to use the central portion of the frame. Better to crop in post where you have more control over the composition & amount of crop...

On my D850, if I put on a DX lens, the camera switches to DX automatically. In fact, the portion of the FF image that is not in the DX part is greyed out. You can see the full FF part, but part of it is in translucent grey. Very nice. I did not set that up when I got the camera.

Good luck.

It is comical, really. It’s obvious to me that many posters only read the OP(original post). Then they post their comment without regard for previous posts.

So the funny part is the joke is on them, because the next person like them(only reads the OP post) never reads their post! Lol
