K20D AF-C improvement?

.

Has anyone with a K20D noticed better AF-C compared to the K100D or K10D?

The AF-C focus mode seems to be vastly improved on my K20D compared to my K100D Super. AF-C just didn't seem reliable on non-SDM lenses on the K100D, but I just was shooting with my Tamron 18-250 on the K20D, trying AF-C - noticeably better.

I'm wondering if it's an improvement in the K20D, or if I'd see the same level of improvement in the K10D - it's always seemed to me that K10D users had better luck with AF-C than I did with the K100D, at least anecdotally... I have a friend who's very interested in picking up a used K10D if the AF-C is reliable.

Here are some shots taken today in AF-C with the Tamron 18-250 on K20D:

Yes, possibly

Yes, so far for what I have seen for others who have reported or even experimented:-

Write that on your calendar so you can celebrate the event.

Oh no, I don't think I would go quite so far, and in reconsideration, it is clear that someone else has hacked his account and made the comment

if you read his blog, it is essentially a backhanded compliment, which ends in the usual bile about the "stupidity" of Pentax.

What intrigues me is why anyone would do the stated experiment (which is laughable from a design standpoint) and then why someone else would do "analysis" of the "results". Well, it doesn't really intrigue or surprise me...people want attention and being controversial and backing it up with pixel peeping and charts will always garner some attention.

If I shoot 100 shots in a day and get one "good one" I call that a good day. Then again I'm looking for something different, and maybe I have a different metric for what "good" is. Today I shot about 50 images of a black coffee cup. I never really got it "right" or "good", but I got some things that were interesting.

My K20D AF-C works great, especially with the DA*50-135. I never fully tested the K10D, but the K20D hasn't failed me yet. I'm completely satisfied.

Internet conspiracy theory 52398: Pentax did improve/fix the AF, but because Samsung is sill marketing the GX-10 clone, Samsung wouldn't let them claim the improvement as it would hurt GX-10 sales.
