But as you keep pointing out, DSLR lenses are not of diffraction
limited quality and we're discussing DSLR lenses here!

If you actually uderstood what you're talking about you'd realise that
that makes half your comments in this thread nonsense. You're arguing
two logically incompatible positions at the same time.

Is the amount of swearing and cursing you do when trying to educate
others a reflection of how your own teachers treated you when they
they were trying to teach you?

Any difference in number / quality of elements?

What part of; that's exactly why you can't determine what aperture reveals
diffraction being an imaging problem because your lenses are not figured
accurately enough to cause observable diffraction, it's all optics figure
error; do you fail to comprehend?

Time to go educate your useless troll-ass of a self.

I'll leave you to your ****ingly pathetic trolls' ignorance, only for you
to wake up one day (or not) realizing just how amazingly stupid you were
with your words and reasoning on this day. Just another day of many
thousands where you have done exactly the same. Garbage in, garbage out.

Don't use words you don't understand, troll.

Good thing I didn't share the names of the plugins (yes, plural, more than
one do this) that I've used to design my own bokeh effects by defining lens
aperture patterns. Then applied to the gaussian-blur depth-map masks that
they use. Perhaps he is upset that he had to go look up what a depth-map
mask is?

3 bladed (sided) irises, 4, 6, 7, 8-sided irises for star-filter bokeh
effects, 12, 19, etc., elliptical, whatever. Also design the diameter, edge
softness, and annulus width for catadioptric lens bokeh emulations, the
works. Nearly any bokeh that is created by any lens design can be emulated
with this software, as well as bokeh effects that can't even be created in
optical lens designs.

Heaven forbid that someone should share truly helpful and easily accessible
information with troll idiots like you running around ruining it for
everyone.

YOUR LOSS!

And a huge loss for everyone. Caused by trolls like you. Now everyone has
to do the searching for that software based only on a vague description.
Good luck finding my most favorite and vastly configurable one as described
above, I've not seen it on the net for about two years. You useless trolls
taught me well. NEVER share the most important bits of information as long
as a news-group is being overrun and taken over by a pack of useless and
pathetic trolls. The trolls will only use that information to be better at
pretending to be photographers with the next newbies who can't immediately
see the trolls for what they truly are.

I don't believe this stuff exists. Prove me wrong!

Google is your friend.

One such plugin is even unimaginatively called "Bokeh". I don't like the
results but then I have never been into lenses smeared in vaseline etc. eg.

http://alienskin.com/bokeh/index.aspx

Can't say I would recommend it.

I suppose I could upload two sample images, one without and one with a
depth-map catadioptric-lens annulus bokeh applied to it, but ... why waste
my time doing that for useless trolls?

Why should I even prove you wrong? You love being right! Don't you?

Whether you believe I am telling the truth or not is of zero importance to
me. I enjoy using that software occasionally when needed. My favorite one
does a remarkable job of emulating any lens bokeh that you can think of or
have ever seen before. The only difference is that you have no knowledge of
its existence, until now. Oh well! Unimportant to me.

Should I tell you the names for the plugins so role-playing trolls can
learn to be better trolls? Just like the only contact they ever have with
cameras is from downloading free camera manuals. They'd then have some
advanced plugin information so they can pretend to be decent graphic
editors too. They're so ****ingly transparent to someone like me when they
pretend to be photographers in these news-groups. They just refuse to
understand that yet, or they'd go play their silly pretend-expert games
elsewhere.

Go forth and search! You have enough information in the previous post to
find what you seek.

Blame all the useless resident-trolls that you support (or are one
yourself) for not having the information just handed to you for free. Now
you have to do some work to go find the software. Be extremely grateful
that I was kind enough to tell you that software of that nature even
exists.

Have fun!

(Awaiting your next, or some other troll's, pathetic manipulation
attempt--to get some help that you don't even deserve, for free.)

Outing Trolls is FUN!

Never used that one. And from your description I probably won't even test
it.
