Re: IMO the QE of the sensor is more important than size

Personally I think the sensor size is not important at all. The technology behind the sensor is more important.

Here's a chart from photonstophotos:

My case in point:

From the 1st Oly E1 FT to the current 20MP sensor

From the 1st Canon 1Ds to the current R5

From the Nikon D3 to the current Z7ii

From the Sony Nex7 to the A6600

Everyone can see from the chart that the 20MP mFT sensor is pretty much up there with the best APSc and FF from yester years. With advancing sensor tech and materials, I believe the sensor size in our cameras is no longer relevant.

How many of you here think of equivalency when you bring the camera to your eyes? How many of you here think of equivalency when you bring the handphone camera to a scene?

The question is, what do the curves actually mean? 'PDR' doesn't measure anything of much interest.
