Pentax thinks I am too negative.
Me too.
I asked my friend from Prague to retest K-7.
He made it one more time. Compared K20D and K-7.
As for speed. AF of K-7 is faster. Not a lot. No speed revolution. But SDM works better.
BUT the most important (not speed):
K-7's AF is MUCH accurate and very tenacious. Friend didn't see any hunting. Another level of AF.
Very good in tungsten light. Very good in low light - MORE sensible.
K-7 has another algorithms of AF. It's simply different cameras in AF.
D700, for example, is not much faster than K20D in good light. But better in all another aspects. K-7 is the same
One man tried K-7 and said that K-7 is like Canon 5D and better than A900.
(on Pentax forum. Russia)
I know one man who think that A900 is better than D700. He tried both cameras for a long time.
It's very subjectively. IMO
