References needed: While most series size filters had plain metal mounts. Towards the end of the era of series filters several manufacturers started making screw-in series filters that didn't require a retaining ring or hood to hold them in place. If these are used with some lenses the original hood may not fit. (reference needed.)

By far the 625 size is the most common.
