What do we get in current $600-800 Pentaxes with regards to AF coverage?
How does that compare to the $6000 and $2800 offerings from Canikon?
What will we get für $2000 then?
That is what is out there:
D5 vs. K-3: 1DX vs. K-3: D800 vs K-3:
Activate the AF sensor lines between the central 5x5 block and the outer ones and you end up with pretty much the same coverage as a D800 - if they manage to scale up the whole coverage from APSC to FF using different AF optics.
And in no meaningful way any significant less than 1DX and D5.
