I have three lenses, all with different filter sizes.
And I have an IR filter that I used on the G3 - the filter size is different than all three lenses. Just great.
So I was in Ted's at Chadstone availing myself of ten free digital prints that my wife took on the G3, and I told the girl there I was after a step-up ring, 52mm lens filter size to 58mm filter.
Certainly, she said, turned around and just stopped. Stood there for maybe 20 seconds, apparently realising that she had no idea what I was talking about, until the guy serving someone else leaned over to her and said, we don't have step up rings.
On the smiling and wanting to help front I give her top points. Not so much on knowledge.
I might visit Vanbars tomorrow.
