point.

SonC rejoins the picking of nits:

I don't think it's a "Circle of Confusion Issue," unless I'm
confused.  I'm not so sure as you seem to be, there's the
same physical amount of blur among the same negative image
sizes of a subject on 2 1/4 Rollei TLR and a Leica with a
medium tele.  If you're correct using "Physical amount" then
the word should be "apparent," rather than "significant."

I hardly ever hear the term Circle of Confusion outside of
basic photo class, when  a student tries to stump the
Instructor by asking for an explanation of it.  You'll hear
it as the names of photo clubs, and it's the title of a
novel that seems to have nothing to do with photography.  In
Hedgecoe's Photographer's Handbook it rates only about fifty
words in the three hundred plus pages.

See Warren Young's excellent discussion of Circle of
Confusion:

Austin adds:

make a better low light camera than a Leica ;-)

SonC replies:

I dunno.  My comparison experience in this area is limited
to Leica and Rollei TLR. Never been Hasseled, but I doubt
it, judging from the noisy "thunk" Hassies make when they
fire a shot (Except of course, the SWC, which I don't think
"thunk".)

Of course, this thread began when I described the experience
of a very young photographer in 1963, who preferred shooting
sports with a Rollei TLR because he didn't like getting
bowled over by several hundred pounds of football players.

As he grew older, he forsook the shooting of football, and
has taken up the Leica.  However, he still owns a Rollei,
and if forced in the year 2001 and beyond to the gridiron
sideline again, might just take the TLR with him.
