Your issue is a bit of slop in the lens mount. Some lenses can get worn but they typically will fail across different body’s. Here it’s likely the mount springs ar a little soft often an occurrence with long heavy lenses as they can pull on the mount and many people hold the camera body instead of the heavier lens.

The issue is the lens present pin which is that little cone shaped pin on the mount face. It need to be depressed by the lens to tell the body a lens is present. A mount that doesn’t hold the lens tightly will create this problem and if the chrom finish has worn off that’s a sign the mount needs to be replaced.
