I can usually manage to get a good solve with some fiddling, but sometimes the far away things get squashed toward the camera, and other weirdness. I suspect I could iron it out by entering the proper camera specs, but I don’t think the manufacturers specs are in the proper ‘language’ for blender to read. here are the specs from the manufacturer:
