Yes, you are right. It is in 2.83 branch like you mentioned and at least import was working correct in my Blender 2.81. Other branches didn't have that change as I checked.

I can confirm the issue as well. The camera is imported as default 50mm, which is not correct. I have made a three.js WebGL scene and exported it as glTF. In Blender camera FOV is not imported.

Additional context Test files are created using ThreeJS editor, adding some cameras and customizing their fov. Then I export to gltf and glb. I see that the fov is stored in the definition of each camera inside the cameras array of gltf file.

Below is an image to present the issue. I can manually change the camera lens to Focal Length and convert the FOV value in glTF file to degrees to type in Blender. That will correct the problem, but this should be automatically done by the importer.

So to workaround this clone this git repo, and copy the glTF-Blender-IO/addons/io_scene_gltf2 folder to replace your local blender/x.xx/scripts/addons/io_scene_gltf2 folder.
