Been trying to track one of these down for my 20mm f1.7 so I can put step up ring on it.
Devon cameras in the UK have them in stock, well it said they had when I ordered on-line yesterday, with a 46-52 step up ring for my polarizing filter.

So anyone else in UK after the same here you go. Watch the postage as it doesn't take much to push it from around £3.50 to over £8. adding another extension ring at £4.99 did it, so I took one off.
