Are you 100% satisfied with any lens you own?

Obviously not. Just for one example, because no lens provides full

resolution for a (as an example) fast portrait lens at full aperture,
ask yourself, have you ever used it for something other than portraits
where full resolution at widest aperture would have been nice to
have? You must have.
There is no lens I know of that can satisfy anyone 100%, even if the
subject use for the lens is narrowly-defined. There is always
something that can be improved in a lens.


You aren't making sense here, Rich. I can think of quite a few lenses
that quite closely approach optical perfection, and of a lot of people
who are extremely pleased with them

Only stopped down. Few are perfect wide open, if any. Reichman's theory
on why the lesser lenses weren't working too well on the NEX=7 hinges on
the idea that tiny pixels and a particular micro-lens configuration
requires a better corrected lens. This also goes back to Olympus and the
telecentric nature of their lenses. I don't know if he's right about
that, but few lenses, if any are better corrected wide open than closed
down. With a perfect lens, you wouldn't see an improvement with stopping
down.

Being satisfied with something, anything including lenses, is a
personal relationship between you and your lens. One person can be
100% satisfied with a lens that another would think is crap. From
what you're saying, you would be satisfied with a lens that didn't
soften or aberrate or have any more noticeable imperfections wide open
than stopped down a bit. So here's the answer for you: JB weld a post
to your lens that prevents it from going wide open. Simple. Turn your
f3.5 lens into an f5.6 lens. Turn your f1.4 lens into an f2.8 lens and
just forget that it could ever go to f1.4. Think of it as a perfect
f2.8 and you'll be 100% satisfied.

Oh, and don't forget to limit the aperture on the small side to, say,
f11 so you can't complain about diffraction.

LOL
Assuming he didn't need to do all that, and the "perfect lens" was
available, he wold complain about the price. He wouldn't buy it anyway,
so what's the difference.
