d750 nef vs jpg image coverage

[cash_chew]

I setup the camera with 1 SD card capture raw, and the other jpg. While importing the images using Lightroom, I

noticed that the image from the jpg is cropped a little compared to the same image captured in raw. Is this the

norm, or setting-related issue?

<p>I just checked that on my D750 (although putting both images on the same SD card). Both the NEF and JPEG images cover exactly the same area, as expected. Both images have 6016x4016 pixels.</p>

Yes, both files have the same resolution. However, when I toggle both images, I can see that the jpg is cropped a little compared to the nef.

<p>Lens correction activated in the camera - could explain a slight crop on the JPEG image?</p>

Yes you are right! I have the Auto Distortion Control set to ON.

This is another question regarding the Lightroom Setup. I have unchecked the box of

"Treat JPEG files next to raw files as separate photos".

Somehow both jpeg and nef files are imported as separate files in the catalog. I wonder if this feature does not work if nef and jpeg are captured on different sd cards.

(Edit) Confirmed this feature only works when both files are captured on the same card
