I think the notion of FF = heavier lens may not be true

Perhaps that realization is leading you to your usual run about. This was the question you didn't answer:

Put 200/2.8 on a FF camera, take note of your exposure variables. Turn crop mode on (I understand Canon can't do it, but Sony and Nikon allow it). Do you expect exposure values to be off by a stop?

The answer I gave before was...

Useless...

...to people who lack the ability and/or are unwilling, to understand.

Straw man arguments come from those who have reached the end of line. So please try to turn around and get on the right track.

Your lack of cognitive capacity does not make the facts a strawman argument.

Feeling cornered, again?

At this point of the game, "entertained" is how I'm feeling. Thanks for not charging us for the show.

Oh, don't worry, you've been the one on the stage.

...and nothing to do with the question.

If that were so, then we'd be left with one of two situations:

  • The question is meaningless in terms of the visual properties of the photo.
  • The question ignores the context of what role the exposure plays in the visual properties of the photo.

The question is a question. Now, that it doesn't help your propaganda makes you go in circles and such inane arguments remain your signature.

Either you lack the cognitive capacity to understand that the same exposure has a different effect on different formats, or you are being intentionally disingenuous.

Same exposure? I guess we're getting something from you... sort of.

Um, link and quote where anyone said or implied otherwise. No can do? Yeah...

So, what are these numbers? Looking for your awareness.

Well, ISO 125 means that the brightness of the captured photo is amplified by 1/3 of a stop. f/4 means that the diameter of the lens aperture was 1/4 the focal length of the lens. 1/800 means the sensor was exposed to the light for 1/800 of a second.

What do you think the numbers mean?

Exposure values. Now, tell me, how would sensor size change any of these.

Again, your lack of cognitive capacity and/or disingenuous motives shine through. No one said that the sensor size changes the exposure.

Good. So, why do these self professed experts on the subject keep hammering the opposite?

Link and quote. That is, I want a link to the post where someone said otherwise and a quote of where they said it.

In other words, you agree, that if you have f/4 in aperture priority, you would expect 1/800s, regardless of the sensor, right?

Assuming the same scene and metering.

Good. Let me continue to help you walk through this... and we will even assume the metering logic to be identical (based on a light meter) and the scene of course:

You have 35mm f/4 lens on APS-C and 50mm f/4 lens on FF. Now, what do you expect the shutter speeds to be?

Let me direct you to this post upthread:

http://www.dpreview.com/forums/post/52491690

which answers all that, and is followed by a miserable and utter comprehension fail on your part. But, please, "entertain" us by linking and quoting *any* portion of that post that you feel to be incorrect.

I mean, it's plainly obvious that you wish to ignore the fact that you've missed that no one, and I do mean no one, has misunderstood what exposure is, and avoid admitting that the reality is that you have utterly failed, on multiple occasions, the connection between exposure and the visual properties of the resulting photo.

So, I ask once again, that you quote from the link above anything you feel to be incorrect in regards to exposure or anything else.

Of course, you know, I know, and everyone else reading knows, that what we'll see instead is more self-harming posts as you duck and weave.  The least you could do for us is put it to music.
