Nice try, but what you said then isn't what you say now.

Tell us again how Nikon's 91K RGB sensor is used to auto focus the
lens... :-)

I'll leave that to you, you're used to making idiotic claims.

cop out.

the answer is "it isn't".

it's used to *help* the actual autofocus system work in some cases.

I.e. "used for focusing". You have a nack of starting your post with a "Nope"
and then agree with what is being said.

The 91K RGB sensor is not part of the auto focus system. I it is not
used for focusing.

it is part of the autofocus system, since as i said, it is used to
automatically choose autofocus points, something *you* even admit is
the case.

removal of that sensor will reduce the functionality of the autofocus
system. that's how it's 'part of the autofocus system'.

Cool, so how come none of my cameras seem to employ it when "they
all do"?

because you don't know what it is you're looking at.

the coupling pin is stepless which means that aperture selection can
only be stepless.

the steps are a function of the click-detents of the control wheel
or the click-detents of an aperture ring. if the camera is set to
p/s, neither applies.

bottom line, any f/stop can be used. it is *not* restricted to the
standard f/stops and standard increments.

You had to snip out the context. Here it is:

Sandman: I've never ever owned a camera that shoots in f/8.222
nospam: bull****. they all do
Sandman: So they shoot in f/8.222 but record f/8 in the EXIF?
nospam: i've seen non-standard f/stops in images.
Sandman: You said "they all do", so it should be in all images, yet I can't
see it any images from Nikon D70, D80, D800E, D3s, D4 or Sony A6000,
A7 and RX1R.

You have now spent two post failing to support that any of those, let alone
"all" cameras record steeples aperture/shutter in EXIF.

So, more hot air, still no support.

plenty of support, plus as you would say, "it's obvious".

i cited info from nikon that supports what i said, and one look at the
lens mount confirms it anyway.

you're just spewing the hot air bull**** because you can't admit you're
wrong, again,

how is it you get a free pass on 'the obvious' but whenever anyone
else says it's obvious, you say it's unproven, hot air, etc.

Difference is that Floyd posted about the obvious, not me. He joined the
thread and posted obvious things that I had been saying all along.

It's another thing when someone makes a claim and then instead of supporting
it says it's "obvious" when asked to support it.

nospam:
it also has nothing to do with the size of an autofocus point
which is the original issue.

Sandman:
No ****, Sherlock. Again, what I've said the entire time.

then why did you bring up the rgb sensor, if it has nothing to do
with the issue?

Because 'Me' posted about the focusing sensor being several hundred of pixels
big, which they aren't (he later explained that he meant that the correlating
area of the focusing sensor would be several hundred pixels on the same area
of the image sensor - which I doubt either way), which I said was incorrect
and then brought up that the closest thing is the RGB sensor in new Nikon
cameras that does have enough pixels for that correlation to work.

Sandman:
I didn't say it replaced the dedicated focusing
sensors. This was about the claim that the focusing sensors
are hundreds of pixels large, and Nikon is using a 91k RGB
sensor to aid in focusing, especially when it comes to face
recognition and 3D tracking.

nospam:
you're confusing two different things.

Sandman:
Ironic.

nope.

Yes, ironic.

you're trying to wiggle out of admitting you're wrong.

I always admit when I'm wrong.

Deja vu, sounds like something I just said.

I.e. no support.

It would be obvious if any of those camera had stepples EXIF data, which they
don't. Still waiting for support.

i cited info from nikon that supports what i said, and one look at
the lens mount confirms it anyway.

The issue was the actual EXIF data in the images. You know, the thing you said
you've seen in all cameras.

you're just spewing the hot air bull**** because you can't admit
you're wrong, again,

I always admit when I'm wrong, when contradicting facts are shown to me. I'm
still waiting.

The Auto Focus system will work with or without the RGB sensor for the
exposure system. As Nikon describes it, data from the exposure system
is integrated in the Auto Focus for tracking (not for focusing).

I post about you saying obviously incorrect things.

Like you do!

Just to point out the obvious, here is where you said
specifically that the 91K RGB sensor is used for
autofocusing:


"No, this isn't true. Most focus sensor are a couple
of pixels wide and a dozen high. Only lately have
high end Nikon cameras started using a 91K RGB
sensor for autofocus as well as face detection and
dynamic lighting. You can read about it he"

Don't blame others for your poor understanding, or poor writing,
which ever that actually is.

All true. It isn't used *instead* of a focusing sensor array, it is used in
conjunction with one.

Don't blame others for your poor understanding, or poor writing,
which ever that actually is.

Your reading comprehension is well known, yes. If you don't understand something,
feel free to ask and I will explain it for you.
