I understood from the beginning this is a Forum for Leica fans. I have
no experience with those brands mentionned. I can't and have no time
or money for this (I'm not interested so to say). I am no snob and I
sometimes use a P&S cameras (Sony Digital) even when I write an
article or make a note. I made this choice many years ago and never
regretted it, except for the prices and the R-8&9 and DMR saga. What I
like in Leica is its glass in the first place and its precision, even
with large enlargements, in the second place. Third, and I knew it
before studying Photography;  in Photography, you have to be
clean...... and don't put too many things before or behind your lens
if it's not really necessary. When I see a student coming with dirty
pictures (digital or negative) and most of the time too late to
deliver his work but with a lot of excuses I say it once; be in time
and be clean for your work or go elsewhere, your clients will not pay
you for that.

When I see a spot on a print, be it with film or digital, I will never
curse Leica, Hasselblad or Zeiss. I will simply think; "what have I
done there?".

Regards & have a nice W-E.

Cedric
