A high end APS-c sensor like in the D7000 and K-5> low to mid FF sensor. Maybe equal to the latter. For proof, try bringing up shadows in the 5DII and III and see what happens.

Good cams, regardless.
+1 to this.
I have/had K5 and 5D and a K30.
The tolerance to PP and shadow adjustment on the K5/K30, run circles round the 5D.

To TS, my advice is to not look at it in this way.
I like to think/'see' that a lens on APS-C and/or FF gives me a certain working distance/FOV/DOF.
Thinking too much over the 'what it could have been' of FF lenses used on APS-C; equivalence; etc just makes one despair and bitter like the many FF proponents that linger here.

Is the purpose of FF just for shallow DOF only? Is there any IQ different between a crop with fast lens (33.3mm f/2 ISO 3200) vs FF slow lens (50mm f/2.8 ISO 6400) assuming lens have the same quality, sensor has the same technology, DXO standard ISO?
You won't know which sensor was used to capture a shot without looking at the EXIF data.

The negligible differences will only show up outside of real photography, (i.e. shooting test charts).

Sensor size alone means nothing, image quality depends on the whole optical system and method of processing raws. For example, DAL 18-55mm kit lens is very sharp on k100d, but produces awful results on k30. Is it bad or good? Correct answer: it depends.

The same goes to sensors, size by itself means nothing at all. Bokeh depends on sensor size, its filters, pixel size, focal length, lens quality, aperture setting and a way you post-process image. Size is only one variable.

It's like fuel consumption, big and heavy diesel truck eats a lot more fuel then small petrol powered town car.
