Biggus. I remember you mentioning this last time I posted about one of these. Thanks for the link.
However, the other day, I spotted a used Regent Circ. Polariser on the Mifsuds site for £8. I decided to get it (along with a step-up ring so I can use it on my 50mm), for £14 delivered. What should turn up this morning, but the step-up ring, and a new (or so it seems!) Hoya one! Not quite sure if it was done intentionally, as I had quite a strange experience ordering from them - might have been compensation.
Either way, much appreciated Mifsuds
