How Same Lens Behaves on Different DSLRs?

Lately I had this doubt - how a given high end lens performs on different DSLRs of different capabilities. Basically it comes down to the question - how the sensors affect the output of a given lens. For. eg how DA* 300 f4 performs on K10D, K-x/K-r and K-5.

Anyone did such test? Any info available on such things?

Cheers
Guna

Most lenses out-resolve the cameras, so any difference would be in the sensor itself (in which case the k-5 will win). Theoretically, this difference might also affect the presence of CA/PF, but it would be minor.

So top of the line lens + better sensor wins the race.

There are different interpretations of high end lenses. For me, there is no 'race to win', but my best lenses are the ones with the highest rates of keepers.

Simply, I found that I tend to keep a much higher percentage of shots taken with high end lenses (like the FA31mm or FA*300mm). In turn I tend to like these lenses quite a lot.

If most lenses out-resolve the sensors, why wouldn't they all exhibit the same MTF numbers (the max MTF of the sensor itself)?
