Usually, wildlife isn't going towards the photographer in a hurry, so this is the problem in the first place and not the camera AF. Now, is the bird is coming towards me, it is even easier for the camera AF, because the Pentax AF default behavior is to focus from far to near, so the most difficult to achieve for the camera is when a subject is going away from the camera. Ok, in the next three week, I may have a chance to get birds coming towards me :-)

Ok, I want to believe that the best contrast af detect are as good as phase detect real time af, I have nothing against people who would make this choice, based on paper specifications. But, the best is to try in real situation (no only believe marketing propaganda). I truly considered buying a
7DII and Tamron 150-600 for about $2000, so I borrowed it, and I tried in real situation, and
I gave it back... because, the 7DII AF is outstanding... but
when you mount a Tamron150-600 on a 7DII, the 7DII becomes like a Pentax K30 !!! I got a good price for a DFA150-450 and it is a step above the Canon 7DII+Tamron system. If I wanted to benefit from the 7DII, I also had to buy a 100-400 USM II or a 400 f4 , which was from $3000 to $6000.
