Godfrey,
that's interesting. I usually have a terrible fight against my A 1.4/85,
which never focuses where it seems to according to the focussing screen,
on my LX as well as on the KX or the MZ-S.
It's focus confirmation on the latter that gave me hope again. This
beast must focused closer than it seems, focus confirmation is right and
screen is wrong.
I recently made some shots that prove this, done at f/2, so it's a
question of "focus or not to focus". Results will be posted in the
future as part of a little gallery with the title "a new duck in town" ;-)
I also used focus confirmation to test a Meyer Goerlitz Trioplan 2.0/100
against my K 2.8/105 - fantastic! BTW, I went for the Meyer because of
Shel's search for the "glow" of older lenses.
Shel, I've also purchased a Meyer Goerlitz Primoplan 3.5/35 and a CZJ
Tessar 2.8/50, which I havent't tested yet, pictures of lenses and their
results to follow. The Trioplan shows a kind of halo around bright areas
when used wide open, which disapears when stopped down. Winter time will
be scanner time, 'til then I will hopefully have tested these puppies on
B&W.
Oh well, the thread was about focus confirmation - probably focus
confirmation works different on MZ-S and <camera you use>. Or on old(er)
film bodies compared to DSLRs aiming at slow consumer zooms?
Don,
as you shoot digital I suggest you wate some frames to "focus
bracketing", which might reveal you something not only about your focus
confirmation but also about your focusing screen.
I did have some struggle about this with the A 1.4/50, too. I made a
bunch of test shots to find this out Interestingly, the 43 Ltd behaves
the other way round. The K 1.4/50 seems less problematic, at least I got
some decent results on the KX.
Just my 2c,
Pancho

I have not found the focus indication to be particularly accurate for
an f/1.4 lens. It's accurate enough for an f/4 lens. I ignore it
entirely when manually focusing a lens. (BTW, this is why when I'm
shooting wide open with an f/1.4-f/2.8 AF lens, I often tend to switch
to manual focus.)
