Subject: Re: [Leica] Specks in new Leica Lens

Seems to me that if both lenses were at the same dealer, they might have
been mis-handled (dropped) and something on the barrel landed on the glass
inside the lens.

Just a thought. I've never seen any black specs on my lenses.. unless I
sneezed on them ;)

Recently when buying a new Leica 90 APO Summicron M lens I noticed that it
had a couple of small black specks on one of the inner lens elements. I
asked to see another one, as the dealer had two in stock, and this too had
the same black specks. As I was offered either lens at a price slightly
under $1300, I bought one of them. The lens has on closer inspection in a
addition to the above small specks about four other very, very small almost
invisible specks as well. Does anyone know where these black specks are
likely to have come from, i.e. the aperture blades or black paint from the
inner barrel? If it is paint flecks, can I expect to get more of them as
more paint comes loose? Is this common with some Leica lenses or is it a
problem with this particular model? I have two other Leica lenses, a 35
Summicron Asph and a 50 Summicron and they don't have debris inside of them.

I would of thought that Leica quality control should be able to detect these
type of things and rectify them before sending them out. Perhaps they don't
deem it important because irrespective of these specks (flecks?) my 90 APO
is one razor sharp and contrasty lens.
