and what's wrong with K-7 tracking, maybe you don't know how to use
here is one of my examples K-7 + slow DA 55-300 + AF.C mode.



Anyway I'll buy K-5
Sure, this pic shows good following of the subject, along with some nice technique of panning and perhaps some other PP which I would not be aware of.
However, as I mentioned several times before, AF-C "tracking" strenght can only be ascertained if the subject is moving toward you. Lateral tracking is another thing altogether.

Don't get me wrong: I have the K7 and do quite well with moving subjects, with AF-S.
AF-C just doesn't quite cut it for me "yet".

IMO. if your looking(specifically) for tracking, then I'd say go with a Canon(7D perhaps?). Mainly because it clearly has the lead in AF performance. Either way, it's up to us(the consumers) to do our homework and prioritize our needs so as to end-up with the right product. Given the flow of reviews and end-user data going on these days, there really are no excuses for people to end-up with products that don't suite there needs.
Maybe you're right, John; but we can't really say for sure yet.

Not specifically looking for the best tracking out there .... I would have considered another brand, but at least some improvement in consistency of acquiring the image with moving subjects toward the camera.
Have I not made myself clear enough on that?

If the K5 can produce a better "keeper rate" than that of the K7, in AF-C, that will be enough to get me upgrading to it.

I am not looking for a tracking device as sophisticated at that of an F35 (fighter aircraft) Electro-Optical Targeting System !

Cheers.

That would have been a pretty good picture if it was sharper.
Its sharp enough for most print mediums as long as it's not blown up huge.

Nevertheless, I think a lot of AF complaints result from user error, not camera problems. I used to think the AF on my K20d sucked until I played with my friends Nikon D90 / Canon 5D. Those cameras have slightly faster, slightly quieter AF, but it was my technique that was keeping me from getting the shot and no amount of cybernetic photographic enhancement would help me unless I learned how to shoot . So now I just use manual .

Interestingly I have been doing a search lately about the K-7s lack of predictive tracking and came across a superb set of pics taken 8 months ago with the camera and Sigma 100-300mm f4. The poster was more than pleased with the test and seemed happy to show (and prove) that the K-7 does indeed have some sort of tracking.

I then noticed he had no new posts in the Pentax section and saw that a couple of months later he bought a D300s because he kept missing shots.
Ever consider getting the right tool for the specific job?, He did and I bet he is not bitching anymore.

That is an awesome shot, full of motion.
Well done.
