Nuno, obrigado! Thanks for the tips. In fact I even tried to include some landscape with the 16/3.5, which was in the trip too, but the scenarios were terrible, a far cry from yours or those of Peter/John. And the city was close so too much light pollution.
Leighton, If I remember was someone here that suggested the use of Birchwood/Casey Superblack instant touch pen. Depending on your lens you would need a "flat black" or a "gloss" version. I have both. Good luck in your conversion. If possible document it to show us over here.
The Birchwood Casey instant black is a paint based coloring for metal in a tube with a felt tip as an applicator. You can achieve a similar result with any good rattle can black applied with a small brush or cotton type swab.
However, Raphael suggested the use of a "professional" Sharpie marker that works well on aluminum. In fact I colored the whole barrel of my $20 Nikon 80-200 F4 using it.
Gun or metal bluing does not work on aluminum and there are no "home hobby" anodizing products I am aware of.
I'm off to the surgeon .....
