Fx and Dx lens conversions

[Clovishound]

I'm afraid there is no way to avoid the vignetting of a DX lens mounted on an FX camera body. The lens simply does not have enough coverage to fully cover a full sized sensor, as they are designed for cameras with a sensor half that size. You can still use a DX lens on an FX camera, it just has to be in DX mode, which uses half the sensor. Unfortunately, it also cuts the MP rating in half as well.

It looks like that adapter is to adapt a G Nikon lens to Fuji X. I know, the FX looks like it should be a full sized sensor Nikon camera, rather than a Fuji X.

Thanks for your reply. The adapter is to avoid the dx crop effect on the full frame fx camera. It would work, but for some
reason the adapter does not fit securely the on the f mount camera. Lens: A nikon 200mm zoom telephoto dx f mount to camera: d780 fx, f mount via adapter: Fotodiox Lens mount adapter Nikon G to FX

I have looked at the Photodiox website. There is not any F-mount adapter that looks like that. Photos appear to be some adapter for a different camera. You don't show the part that goes into a camera body well, but it clearly does not have enough depth to be F-mount.

Long story short, this item is not what you think it's for. Furthermore, there is no adapter to do what you want to do. Full-frame and crop-sensor bodies for Nikon DSLR use the identical F-mount. You can fit a DX lens directly on a FX body and many Nikon bodies automatically sense that and will crop the image to avoid the dark corners. FX lenses (of modern vintage) always fit on a DX body and will work. Autofocus may or may not work depending on the combination, but it will meter and take a photo.

If you want an ultra wide image, you must get a wider angle lens.

Check out the link I posted in my last post. It looks exactly like the photo the OP posted. This is the image from that link. Like I said, it's for mounting a Nikon G lens to a Fuji X series body.

Thanks for researching for me. It does fit the lens and if it fit the camera right, it did eliminate the crop. But I do know the DX and FX work on my D780. When I purchased it, there was no indication it was for a Fuji camera. I am sure if I go to my camera store there may be someone who could use it? What about an adaptor for the canon rebel t3i to the nikon d780? Sometimes I like to work with lighter lenses. I have 1-nikon & 1-tamron lens for my camera now.

Plus nikon dx lenses. I will need to get used to the crop if I chose to use the lighter lenses. Ty.
