I know someone who owns a Nikon D7100, combined with a FX 28-300mm lens. He says it is his favorite lens.

An fX lens gives exactly the same fov (field of view) as a dx. For a FX lens or a DX lens you always multiply (1.5 Nikon) for the equivalent MM on a dx camera body.
Revise your geometry will you?
If you use only the center of the lens the angle USED is narrower so the field of view will always be different. You can fill the smaller sensor by stepping back bur due to the angle change the resulting image is different. The lens stays the same, there is no change there of course no one is claiming otherwise. The magnifying ratio is 1.5 (in a Nikon DX), in addition to the change noted above.
Reference since you folks do not seem to understand... Plenty of drawing too...

Inside or outside the camera?

The lens does not 'adjust' to the DX body. All Nikon and Canon (and maybe some other make) cameras that I am aware of that are APS-C (Crop Sensor or DX) can take full frame lenses. Not the other way around although as mentioned, you can put a DX lens on some bodies like the D810 which just crops it's view to match the lens. I have both a full frame (D810( and a DX crop (D500) and use my FX lenses on both cameras. I have never put my DX lens on the D810... no need as I have the equivalent view in my FX lenses.

my granddaughter wants to use Nikon 7-200 f.4 with nokon camera 7200 dx camera with fx lens can,t afford fx camera what do you think thanks
FX glass is generally better, but not always. I own both of what you described above and have used the combination for my grandson's sporting events with perfectly acceptable results. She should feel comfortable with the combination.

Suggest you get on to YouTube and look at the "Angry Photographer" videos on lenses used on FX/DX Nikon cameras. A no nonsense guy on lenses.

DON'T WASTE YOUR MONEY ON FX LENS. DX WILL WORK ON BOTH WITH NO ISSUE OR LOSS OF FUNCTIONALITY EXCEPT IMAGE CROPING.

I don't know about a link, but an FX lens on the DX body will exhibit an image similar to a lens 1.5 times its stated focal length.

Perhaps another "search" is in order.
Love the all caps,adds credibility!Feb 8, 2017 09:56:00 #

Actually, on my D810, there is a DX setting so I can use a DX lens just like a DX camera would.
That is true on all of Nikon's FX cameras. The DX camera have a crop setting to that takes the "apparent" magnification to 2x instead of the native 1.5x of the mm lens size.

Of course it does not. WHERE did you see me state that?
Not one lens adjusts', FX or DX. In some FX bodies the camera does a 'smart crop' (menu setting) when using a DX lens. This does not change the lens or the sensor. Anyone who thinks that believes there is a fairy in their camera too.
One note: When using a DX lens on a FX body the lens characteristic stay the stay the same. There is no angle variation unlike FX lens to DX body combination.

A DX lens, when used on an FX camera will vignette (especially at wider focal lengths) & also seriously reduce the resolution of the resulting image. Thus a D800/810 will give an image with many fewer pixels when a DX lens is used on it. Using an FX lens on a DX format camera uses the image from the central portion of the lens, where the image is less compromised as opposed to the edges.. DX lenses are designed to produce a smaller image circle for the smaller sensors in DX cameras. If the OP ever steps up to an FX format camera, they will suffer in more ways than one by only having bought DX format lenses.

just my .02 but your almost always more likely to get the best optics with full frame lenses regardless as to what camera body you attach. As they say a great lens on a lesser body will always give better result than a great body with a cheap lens. The upside, if you always buy the best full frame lens you can afford you will already have great glass when you do upgrade the body.
Like I said, just my .02

BS...lol!
There are optical unintended differences that are "acceptable" but the FX lens was designed for use on an FX body. Otherwise there would be no need for the dx series. Smaller sensor cameras will loose one stop of light as an added negative. The comment is propaganda from a person who does not understand the difference and has an assumption based on a lack of understanding. Sorry if that sounds too negative but its true.
