MacroAgain: DustBrush

Macrorings and one of my lense put the focuspoint from anywhere between a couple of centimeters from the lens, to a couple of centimeters IN the lens. The latter as you can imagine, isn't all that usefull.

But it does mean you can focus on the glass, and so you can

* press a very small brush against your lens
* focus on the front of hairs
* see all the dust on your lens perfectly because they are (for once) focussed.

(disclaimer: i did use a cheap uv-filter so i didn't actually focus on the lens-glass, but on the filter. sue me..)
