[Leica] Lens caps

[hoppyman at bigpond.net.au (G Hopkinson)]

Fair enough B.D. just a bit of levity in the proceedings ;-)
As I say, I don't know what ROR is.
If you have a choice between two similar lenses, one cheaper but with some
marks that may not affect the output significantly and one pristine but more
expensive, which one do you buy (to use or collect)?
Cheers
Hoppy

ROR may not carry instructions in German, nor is it branded Zeiss, but it is
a stunningly good lens cleaner.
