I’d actually be interested to see it on a black one. It might look like “brassing” on an old, well used camera.
Whilst I like that it increases the “tooliness” of the Mac it’s not of me I think.
I like mine pristine. ”There are many like it but this one is mine”, yada, yada.
“Many like it there are. Mine this one is”, Yoda, Yoda.
Worn anodizing on aluminium doesn't look anywhere as good as brass under lacquer.
