Hi Nick,

From what I can see Hoya don't make 48mm LOL For the price of a B&W I could virtually buy another QL17, but thank you for taking the time to suggest alternatives which I appreciate.

I guess those are cheap enough to give them a try and if it isn't up to scratch I could always throw it in the box with all my Hoya's of different sizes I very rarely use
