i'd like to see the AF improvements as well, both on the k5 and kr.
this is one feature that's holding me back from jumping right in. from the k10 to k20 to k7, there have been improvements in AF, but more incremental improvements more than "big leaps".
i hope the one on the k5 is more than just incremental.
i must admire the nikon marketing engine. they really know how to flaunt their stuff.
the D7k has such great exposure that it really looks great on paper.
Sure, both k5 and d7k have features that the other doesn't have and vice versa, but ask a noob DSLR user wannabe and 9 out of 10, they'll pick the d7k.
You can't help but see what they flaunt about the D7k on the nikon web site. features, features, features, regardless if one uses it or not.
i couldn't persuade a colleague to go Pentax because it doesn't have tethering and he needs it, so please Pentax, if the k5's hardware supports it (and kr), make it a feature. enable tethering.
so far, i'm on the fence. hopefully the K5's AF is much better than the k7/kx. hopefully AFc tracking works better also, then i wouldn't care about the d7k's 39pt AF.
