The Reality of the "Crop Factor"

[Kayaker72]

Rick...thanks for the clarification and additional testing.

There is a lot to that conclusion. On one hand, if you want all the reach you can get, 1.2x is something. On the other, it is pretty impressive how far away from the "ideal" 1.6x it really is. And this is just "resolution" and not considering tone, color, noise, etc.

Again, thanks for the comparison.

7DII : sensor is 22.4 x 15 = 336 square mm's
20.2 million/336 = 60,119 pixels/sq mm

1DX : sensor is 24 x 36 = 864 square mm's
18.1 million/864 = 20,949 pixels/sq mm
