...have a look at this comparison on DXOmark between the Pentax macro,

the 30 mm and the 45 mm Samsung:

...U see that the Pentax 50 mm F2.8 macro is (according resolution and overall performance) by far the worst lens of the bunch.

Need to be careful abot DoxMark lens test. It includes the sensors resolution. The Pentax 50/2.8 is tested on a K20D which is a 14m camera (I think it uses the Samsung sensor as in NX100)

I also found it strange that DxoMark gives the NX 30/f2 a higher score on sharpness than the Zeiss Touit 32/f1.8 with the Nex 7.

Still, I don't see any reason why DPR uses the Pentax lens other than they just have it on hand.

Yes,

but it is the same outcome as with the K5, which has a 16 MP sensor...

...the Pentax lens still achieves only a 8 MP equiv.:

...which is a sign, that the lens is more the limiting factor, than the sensor...

...and therefore in any case unsuited to test cameras with more than about 14 MP.

-

...a test with the Pentax macro on modern cameras is not that meaningfull...

...to say it diplomatic.
