Fix discrepancy between camera focal length and viewport focal length.

Navigate viewport to find a nice camera angle.

Ctrl + alt + NUM-0 to move the camera to that position.

Go back and forth between Camera Perspective and User Perspective.

The scene does not look identical in both views.

The viewport says its focal length is 50.

The camera says its focal length is 50.

The scene does not look identical in both views.

Change the camera focal length to 25 and now it looks identical! OMGWTF?
