Originally posted by sezme As a D700 and K10D owner, I think you are either grossly underestimating Pentax's AF, or grossly overestimating the AF every other camera on the market. The truth is that there isn't nearly as big a gap as common wisdom would indicate.
I'm comparing the K200 (and K20) with the D80 and D300.
I have tried the four of them.
The Pentax cameras have a much much slower AF, you can try to turn this around all you want, but this is a fact.
The D80 can focus
instantly, while in the same condition the K20 takes its time and waste me something like 1 second because it locks the focus.
This is very, very, very annoying in some situations.
I'm not saying that Pentax have bad cameras, they have great cameras with great features, some of them cannot be found even on the highest models of canonikon (like build it SR).
However, ignoring the fact that the AF is very slow compared to anything else - is silly and will get you nowhere...
