What really makes big sensors produce more appealing images? *Serious*

you did brought it up . . .

You're asking us to move on about an issue you brought up in the first place

The background blur is given by diameter of the front objective, or the FL divided by the F-stop

Oly = 75 mm / 1.8 = 42mm

Canon = 135mm / 2.0 = 68mm

If you don't care about an additional 62% blur, you're unlikely to care about any of the other technical benefits either.

But I do kind of agree with you, and you can check my original response to this thread. The more experienced photographers do tend to use the best equipment, resulting in images that are better than what the better equipment alone would warrant. Odds are, the same photographer could produce stunning images with a smaller camera. But why would she want to?

The Oly 75mm at f/1.8 would have rendered the background in a very similar way, and of course adding an extra dollop of blur in PS on top of the additional PS blur she used would be no big deal at all. You and Just another Canon have scored your technical point about the difference in background OOF between f/2.5 and f/5.6. Now time to move on and seriously address the real issue of whether the "magic" of this image is uniquely due to it being shot FF.
