Yeah, that's crazy talk and easily disproved by anyone who owns two cameras with different sensors.

The thing is, I can say that this image has more bokeh than that image and everyone will understand what I mean, but some pedant will invariably turn up and say "You can't talk about quantity of ...

Exposure is a common red herring that people who disagree with equivalence often bring up when nobody is talking about exposure. Yes, you will get the same brightness and the same exposure when you ...

Actually when originally introduced to the English language it simply meant out off focus blur, but over time people came up with some strange rules such as you can't talk about the existence of ...

True, but equivalence isn't about exposure. Equivalent photos taken on different formats necessarily have different exposures because they use different (equivalent) f/stops at the same shutter ...

In other news, MFT snarkiness seems unaffected.

Brightness is related to exposure (per area) not total light and the relationship between exposure and brightness depends on the ISO setting. All ISO does is give us the brightness we expect at a ...

OK, so your are talking about ISO, which isn't really gain and I don't think Tony used the word gain in that section of the video. Tony did make some mistakes there though about what ISO is and ...

First please define what you mean by "gain". Are you talking about the electron/ADU conversion, or about ISO, or something else?

The problem comes from thinking of the data recorded by the sensor as having brightness that is then amplified by gain to the final image brightness. The levels recorded for each pixel only matter ...

It makes no difference if the sensors have one pixel or 50 million pixels, and it doesn't matter if they both have the same pixel counts or different pixel counts. It also makes no difference if ...

If the shutter speed is the same and the intensity is the same, then the brightness is also the same at the same ISO. Without ISO there is no output brightness because it is the ISO setting that ...

The sensor input intensity doesn't translate directly to output brightness because intensity is only one part of exposure. The exposure also depends on the shutter speed, so a given intensity of ...

There is no "basic algebra" in your arguments, just leaps of logic that have led you to a false conclusion. The light hitting the surface of the sensor is the same intensity (or brightness) at the ...

But that's not what you were describing in the post I replied to , you were talking about the same f/stop on both FF and APS-C, then through some twisted logic you came to this: Here you are ...

"Brightness: the perceived lightness of an image as produced by a given exposure combined with any subsequent amplification and/or transformation applied to it either in-camera (including adjusting ...

Brightness is how bright the image looks. Images with the same brightness have the same pixel values and the histograms look the same. Output size has nothing to do with it. The brightness of an ...

If you shoot the 12mm from the same distance as the 200mm the 12mm won't distort the face, it will look the same as the 200mm shot. The perspective distortion comes from the subject distance only ...

Brightness doesn't depend on sensor size, final output size, or photons per pixel. It depends on exposure and ISO. If you use the same f/stop and shutter speed on FF and APS-C, the FF will get ...

You're right. MFT is amazing and blows FF away. Thanks for setting me straight.
