The K-5 combo wins in resolution in general.. E.g.:-
..and seems to have better details and more favourable colour responses:-
Well, how come the colour of the cropped 60D image has become B&W btw? :-o
But then the 60D is tested to have lower ISO noise throughout the range:-
But yet, the K-5 images are having better clarity and retain more details.
Last but not least, the colour tendencies are checked with the Imatest:-
A quite nice test and comparison overall, but whether you're to agree with the results or not is up to you! As usual, I blog, you decide~

That fine lens also needs a Pentax FULL FRAME camera to use it on.
Make it happen Ricoh!

They should compare the FA50 to the EF50 then this test will be fairer.

Quoted, "Unfortunately, though, we have serious concerns over two issues with this lens which have to temper our enthusiasm; namely optical alignment and autofocus (which are quite likely related)... This does more than simply mess up our studio tests - it clearly results in real-world image quality and focusing problems too. In fact we've never before seen a lens so capricious when it comes to focusing - we're used to F1.4 primes being challenging for cameras' AF systems, but the 55mm was most difficult of all. We couldn't get any of the tested samples to focus sufficiently accurately for reliable shooting wide open without resorting to focus adjustment.."

Per the same review: "(DA*55mm) is a particularly good match for the K-7. The large focusing ring is especially easy to use, and the focus mode selection switch is well-placed for operation by the left thumb."
Slower AF? sure, that happens per design to portrait lenses like this with a long throw. Perhaps bad choice for a dirt bike racing.. :o) (DA*50-135 does fine though)

I bet it's the latter. There is no doubt the K5 sensor outperforms the Canon sensor in all regards, except a bit of resolution.
I'm surprised by the noise figures. The K5 should clearly beat the 60D's sensor in this regards which suggests they are using JPG. Canon is notorious for applying more NR to their JPGs than Pentax which would explain why the Canon has less noise but also much less details despite its higher MP count.
