I want to join the 'Cult of Sharpness' - anyone else in?

You know you want to.

If there are enough of us we can force lens makers to make sharper
lenses.
If not, they will continue to make 'defective', (i.e., soft) lenses.

Are you in?


there already are sharp lenses out there, what your probably confusing
them
with is "cheap" lenses
If you want sharp you have to part with some folding first :-)



I learned that the hard way with the f1.8 20mm Sigma (I call them Smegma)
That thing was soft as ****e.


It was a Sigma, what do you expect :-)
Having said that I do believe that they do occasionally make a sharp lens,
but its a lottery if you get one, and the odds are about the same :-)

Apparently the satisfied Sigma customer is currently reading another newsgroup.

Nope --- I buy my lenses well informed.

You want all sharp lenses? No problem, but forget contrast,
bokeh etc. and add CA, CL and the myriad of other lens problems
one can get. Then you won't be happy, you'll have defective
(i.e. won't deliver a pleasing or even usable image) lenses,
but you'll have sharp lenses.

That's why I don't subscribe to such an aim.

As for cults, that's something for vulnerable sheep and
ego-tripping, often abusive leaders --- maybe just right for
you, but not for most people.

F'up,

What difference does buying the sharpest lenses make if you are going to
put them on a camera where the mirror slap and shutter slap shake the
camera so much that you can never make use of their full resolving power.

On reconsideration, I take that back. There is only one situation in which
you can use any D/SLR lens' full resolving power. If you mount the camera
on a sturdy tripod in a pitch-black room, lock up the mirror, use a slow
shutter-speed (about 30 seconds to wait for all vibrations to dampen down),
triggered on hand-free time-delay or with a cable-release. Fire a flash
mounted off-camera because the firing of the strobe imparts its own pulse
of motion, detectable by anyone who has held a firing flash. Trigger the
flash pulse 30 seconds after the first curtain opens, while both curtains
of the shutter are still open, to create the exposure. Using a 2nd curtain
flash-sync setting if you have one. Only then can you detect or use a lens'
true resolving power with your D/SLR camera.

A unique shooting situation but the only one way where you can accomplish
this task.

(Wondering when they're ever going to get smart enough to figure this stuff
out.)

Go away, idiot troll. Nobody's interested in your cult.

What difference does your opinion make when your facts are
all wrong --- again, as usual and expected by now?

Fire a flash
mounted off-camera because the firing of the strobe imparts its own pulse
of motion, detectable by anyone who has held a firing flash.


Oh, yes, the photons provide *sooo* much pulse of motion!

Once you combine a couple million flashes, you could slightly move
a very thin piece of paper with a synchronized mass flash ... as
it burns to ashes from the intense light.


Yo, slime, thanks for the proof you never held a firing flash,
either.

Showing that you've never even read the tests done on this problem, nor
tested it yourself.

What's the matter? You don't own any camera to test?


Fire a flash
mounted off-camera because the firing of the strobe imparts its own pulse
of motion, detectable by anyone who has held a firing flash.


Oh, yes, the photons provide *sooo* much pulse of motion!


No, you pathetic "can't dazzle them with brilliance so baffle them with
your bull****" moron. It's caused by the discharge in the capacitor and its
dielectric layers responding to the release of energy. **** are you ever
stupid. PROVED AGAIN!

ANYONE with a flash unit can fire it off with the test button on it and
feel the jolt occurring from the capacitor discharging.

Oh wait, that's right. You have probably never even touched a flash unit,
nor any camera. You just proved that by refuting that flash units don't
impart a pulse of motion when fired.

a very thin piece of paper with a synchronized mass flash ... as
