I assume the answer, but looking for confirmation.

If you place a DX 18-200mm lens on a Nikon crop sensor camera, the field of view is equivalent to 27-300mm.

If you purchase a full frame (FX) Nikon and attached an FX 28-300mm lens, will the field of view be the same in both cases? So for example if I'm shooting a cabin on a mountain from ground level and zoom all the way out on both lens, the resulting picture of the cabin will look the same?? I think yes. So if yes, I wouldn't lose my "reach" by switching to an FX camera?

Thanks in advance for your comments.

No an FX 28 to 300 on an FX camera is 28 to 300. you may crop it to match the dx framing or in a lot of cases you may change a setting in your FX camera to crop the same as a DX.

You wouldn't lose your reach if you use a lens 50% longer on the full frame. If you use the same focal length lens on both cameras, you get more reach on the crop sensor.

You would have approximately the same field of view.

Except for minor differences between the two lenses (specifically tolerance on the focal length) the field of view of a 200mm lens on a DX camera will be exactly the same as a 300mm lens on an FX camera.

The field of view will be the same. The cropped sensor camera is going to give you more depth of field because you are using a shorter focal length to achieve the same field of view as the FF. I did some testing once with a Nikon Df (full frame) and a Nikon D7000 (1.5x crop sensor). I made diptychs from them in Photoshop for an article I put in my camera club's newletter.

Bottom photo from cropped sensor - more depth of field. I focused on a pole 108ft. away. This container was 37ft. away. I had a 100ft. tape measure with me.

Only difference in field of view on 27 on the DX and 28 on the FX. Not enough to think about = dave

Whether a lens is an FX or DX lens, the focal length remains the same; i.e., the focal length stated on the lens. A DX lens has a smaller circle of confusion; i.e., the round image it projects onto the camera's sensor has a diameter that approximately matches the corner to corner length of the rectangular sensor. Since the CoC on a DX camera is smaller that of the CoC on an FX camera because of the DX cameras smaller sensor, the FX camera's sensor will not be filled by the DX lens. Therefore, only a portion of the FX camera's sensor will be used and the number of megapixels used will be less than that used when an FX lens is used on the FX camera.

On the other side, if a FX lens is used on a DX camera, the CofC will be larger than the DX camera's sensor and what the lens is seeing will be cropped rendering a photo with a magnification of 1.5. For example, a 28-300mm FX lens used on a DX camera will appear as if it was taken with a 42-450mm lens (1.5 x 28=42 and 1.5 x 300=450). So the angular field of view will not change when the DX lens is used on the FX camera, but the angular field of view will change when the FX lens is cropped on the DX camera.

So, will my cabin look the same based on the example I gave (DX on DX vs. FX on FX when both are zoomed out to their max.

But is your answer to the OP's question YES or NO?

Sure, when the FX lens is 50% longer than the DX lens.

Yes the field of view of an 18-200 on a crop camera is theoretically the same as a 28-300 is on a full frame camera. At least at infinity. The 28-300 is one of those lenses that suffers from severe focus breathing and it will only give you a focal length of 135mm at it's closest focusing distance at 300mm.

At 300mm on a DX lens on a DX body, the image will be approximately the same as a 300mm FX lens on an FX body. But, on a DX body, an FX lenses image will be cropped so it will appear more telephoto.
