I haven't pulled the trigger for a K-7, because I am quite happy with my K20 IQ wise, and I prefer not to have two cameras, but rather prefer to invest on lenses...
But the thing is... that I am frustrated by the fact that most people don't know: AF depends on light, and wave length of the light can make the AF miss. For example... tungsten light. Or even... candle light.

The thing is... that Pentax have claimed that they did something in that respect.

So, the question is... how much is it improved? Does anyone have both cameras to compare AF in those conditions? I hardly see myself selling my K20 for AF speed or 5fps.... but this could be a great fact (as well as high speed flash metering, which I really like of my K20).
Thanks a lot.
