Just noticed that the aperture control arm on my 50 1.4 AF-S has a small scratch (the black coating is gone and bare metal is exposed), probably from rubbing against the body-mounted aperture control lever on my D90. Started me thinking....then obsessing....about where that sliver of coating went. Pehaps flying around my shutter-box? My question: does anyone else notice any such issues on their lenses' aperture control arms? I feel silly thinking about such things but, hey, if a piece of dust can ruin a shot, a bunch of metal coating slivers building up over time can probably do much worse.

You must really be shoving your lenses in there, none of my lenses aperture control arms are warn down.
Metal shavings are in your breakfast cereal so I don't think there's anything to worry about if you find them in your camera ;^)
