     Series filters were widely used on vintage cameras for decades.   Some large series filters are still being produced today for use with cine lenses and super telephotos.   The main type of series filter system uses an adapter which attaches to the lens.  This adapter will either screw onto lens threads or slip on and over the lens collar.  A filter that matches the series size drops into the adapter and a threaded retaining ring screws onto the front threads of the adpter to hold the filter in place.   Some series filters thread directly onto the lens but it is important to know that the thread pitch used on vintage lenses does not match the thread pitch used on modern lenses.   Do not use series threaded filters on modern lenses and vice versa.  Some filters have a slip-on adapter built onto them.   These are usually camera specific.  A few rare adapters use a set screw to tighten around the lens collar.

Adapters

     There were hundreds of different sized series adapters produced over several decades.  The system is extremely versatile.  Some adapters are labeled with thread size or collar size, but some aren't.   Many adapters use a code # or code letter for identification.  Each manufacturer used their own system.  Below is an incomplete lists of codes.   These codes and measurements may not be 100% accurate.   These adapters came with male and/or female threads though female threads are rare.   Ednalite adapters came in very precise sizes compared to Tiffen.  If you are having trouble fitting a Tiffen adapter, try Ednalite.
