Thanks for the feedback everyone. I wanted to post a link to my Flickr so people can check out more photos from the shoot at larger sizes:

Here is a link to some of my previous sports shots, including some shots from the K-7, K-x, and K-5.
Sports - a set on Flickr Originally posted by GlennG That sums it up well both my experience with sports and where I am right now regarding an upgrade. The AF/sports issue aside, I am happy with almost all other aspects of my k100dS, so much so that I'm continuing to question my upgrade want. With the growing and very good indications for the K-30 such as in this thread it is likely that I'll upgrade to the K-30 later this year - maybe Black Friday? Regarding C&N, any upgrade does not have to beat those, or any other brand, spec for spec. But the upgrade model does have to be "fast enough" for amateur sports, and do better in low light/high iso than my current model. Here, I've received a good indication that the K-30 plus good glass would be sufficiently good.
I believe you would be satisfied with the K-30s performance based on what you describe you're looking for. And as a former user of the K100D Super (I bought it for my sister, very nice image quality at low ISO, even today) I am excited for you to experience the upgrade in performance in virtually every area. As a manual focus fan you'll probably also enjoy the focus peaking.
Quote: Of course, he did use the DA* lens, so it certainly seems better than older models. I wonder what performance is like with the 60-250 compared to the Sigma?
I actually am really pleased with the focusing speed of my DA*16-50 and DA*200 (rivals the Sigma 70-200 imo). Also, believe it or not, I have yet to have an SDM motor problem (knock on wood). If Pentax came out with an updated DA* 50-135 with a fast and more reliable motor that I could use for both events and sports I would be willing to shell out the extra money for the improvements. If they don't bring out a full frame camera (or maybe even if they do) they're going to need to come out with some new lenses to compete. I don't see the point of them releasing a king of the hill APS-C camera like I think the K-3 may be and not having the lenses to go with it.
If you have any other questions let me know.
