That's comparing Samsung vs Sony Exmor and there's a lot more than the bit depth which separates the two sensors.

A comparison of K-01 or K30 vs K5 would compare the same Sony sensor, but one with 12bit and one with 14bit oputput. From what I can tell, the additional 2bits have only a subtle effect on IQ even if your torture test the files.

On that example the K-01 is on the left, the K5 is on the right, both images 400ISO DNG files, with the same amount of fill and brightness added in LR3.
So now many stops can the k-1 be increased decreased by in Lightroom? I assumed the extra 2 stops headroom was down to the 14 bits...

Re press photographers you ussuallu find they have a ff body with a 24-70 attached and a crop sensor body with a 70-200 attached to take advantage of the crop sensor...

Oh and if you shoot at 7fps the yn560mk2 keeps up when set below 1/8 power setting

I have the yn560 mk2s and they work fine on my k-5.

I bought two and one stopped working after a couple of weeks, sent it back to china and was replaced within a week.

They look really good and whilst they don't have pttl are really easy to use, a lot simpler than my Metz af48 which cost 3 times as much.
