Then, any lens with "DX" on it (like my DX 35mm 1.8G) will also be the same.
Man, do I have a lot to learn!
I guess the DX lenses are designed to focus (fill) on a smaller surface area. OK, that makes sense.

Is there a way to override this, or do the FX bodies all simply force “DX mode” when a DX lens is mounted?
I just now mounted my 18-55mm DX lens on my F2, as an experiment. It turns out that any any focal length greater than about 24mm, at least as seen through the viewfinder, it appears to cover the full frame. I know this lens isn't meant to be used on an FX body, but if it were, it seems like it'd be really dumb for the body to just automatically, and with no option to do otherwise, crop down to just a DX-sized piece of the sensor, and discard the rest of the image outside that piece. As I said, at 24mm or longer,it seems to cover the full frame, and less than that, it seems to me that it'd be much better to allow the photographer, in post processing, to crop the image as he sees fit, to deal with any vignetting issues.
On an unrelated note, I was startled, just now, having held my F2 once again in my hands after not having used it for so long, and having just now worked its actions, how nice and crisp it feels compared to my D3200; like a whole different level of quality. I guess I shouldn't be so startled. The D3200 is a Nikon, and it is certainly built to a Nikon level of quality, but for a Nikon, it is bottom-of-the-line; while the F2 was Nikon's top-of-the-line when it was built, and it was built in a time when quality standards across the line were much higher than they are now or are ever again likely to be.

Yes there is a way to over-ride this, in the settings you can set it to use Auto DX mode, so when it detects a DX lens it will just use DX mode, or you can have this off and it will use the DX lens in FX and as mike says, it will have a circle around the image.
