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

You mean, "No comprendo".

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.

...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.

Have you see these kind of numbers before?

ISO 125, f/4, 1/800s (and yes, I picked these from one of the images in your gallery).

I must have been using Auto ISO or used ISO 125 by mistake, as I never intentionally shoot intermediate ISO settings.

It doesn't matter whether you had Auto ISO or not. That is irrelevant.

Just saying I never intentionally use ISO 125. But, true, irrelevant to the question you asked, but I did answer it, and answer it directly.

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. What was said is that a competent photographer would not use the same exposure on different formats for the same DOF and shutter speed. What was also said is that the same DOF and shutter speed results in the same total amount of light being projected on the sensor for all systems, and thus the same noise for equally efficient sensors.

Now, tell us plainly: do you honestly fail to understand, or are you being intentionally disingenuous?
