Thanks very much, Llechwedd, that's very kind.
My camera is an Olympus Camedia C-8080 Wide Zoom. It's a "bridge" camera, not a digital SLR, but it will go all the way from a wide angle to super macro with the one lens, with a bit of zoom in between. Its main drawback is that it's very slow to focus and to write to the card but fortunately flowers don't move too fast unless it's windy! I don't think the camera's made any more but it seems to work pretty well.
