Hi Miro,
I think your pulling my leg and that of others with years of experience
and extremely large blow-ups made into posters and exhibition prints,
like 30" X 40" and larger.

You're making this begin to sound like you're one of those all theory
guys and not a shooting guy with much experience.

Pardon me if I'm wrong, as no offense is intended, however my son you're
all wet with this technical nonsense. Maybe you should have a whole
bunch of practical time to learn the truth of what can be done with a
Leica M or R as opposed to what you are pushing.  Quite frankly it
doesn't wash any more than elephants can fly.

You are now without question, speaking with absolutely no practical
experience whatsoever, or you are really trying to get a confrontation
of experience against theory going here.

Before I say anymore would mind very kindly to please explain to the
crew just what you base this drivel on from your ____ practical
experience ___ and for how long you've believed and practiced what you
are espousing?

But what does this crap have to do with real picture taking with Leicas
of any model in the heat of a fire fight, the roar of a crowd at the
Olympics or a Santa Claus parade?  Please get real and don't be so naive
anyone is paying any attention to what you are pushing, as it's sheer
nonsense when it comes down to every day working photographers. Or
amateurs or everyday fun folks taking pictures.

And are you sure your head at sometime didn't inadvertently violently
collide with a piece of metal?  Whew a hell of a criteria.

And good buddy I still stand behind this comment from 50 years
experience. And I'm still doing it and it still works!
