  Mike, The filters for the Summitars are not standard filters, They fit only
the Summitar.
They have a 36.5mm screw thread which is on the end of a conical ring.
You can still get them from most second hand places( Tamarkin etc. Check it on
the internet) . They are normally quite inexpensive. The problem is, you can't
get any new multicoated filters for this lens, unless you buy an adapter from
Summitar to 39 mm
(Summicron 50mm) I don't just now have the part number for this item, but it is
still available second hand. The cost is normally about 20 Dollars. If you are
interested, then I look for the part number of this item and mail it to you.
Let me know.
The Summitar is a good lens. It  is worth while, to look after it.

There is no screw in lens cap available. You have to make do with a slip on
job.
It will fit the normal lens hoods for the Summicron 50 mm lenses.

I hope this helps a bit
