Originally posted by Wired He does have a point about the AF, it still isn't where it needs to be. Screw drive yes, it's quick and it works fine, but I think the SDM motors need an upgrade in speed. I was shooting a bike race this weekend and took the K3 and the two f2.8 DA* zooms with me. It was -24, and even from the first shot the AF caused me to miss. It was easier to manually focus close and then have the AFC take over to track the biker as it moved across the frame. It was okay in that respect. But after the first lap I got frustrated and switched to my Nikon D800, even though I didn't trust it in the snow.
all the advancements Pentax made with the K3 mean nothing if your subject isn't in focus.
That being said, I used it later on in the evening (same lens combo) to shoot a local band in the dim lighting of a pub and it worked very very well. I also did video on it and it worked better than the D800.
It becomes a case of right tool for the right job. For sports, the K3 & DA* zooms are still not there, we need an upgrade on the lens. But for low light concert photography the K3 seems to be a very good weapon. Just to use two examples from my shooting this weekend.
That seems to be my conclusion as well. I would use the K-3 in a heartbeat for 95% of professional photography, save for maybe high-speed action sports. And hey, did anybody ever stop to think "well that' why they charge $6-8K for the Canon/Nikon sports flagships?"
And really, in its price range, what other camera has the AF system that the K-3 has? None, or very few... I have always admired Pentax for their interest in bringing "darn good" to the masses and even the beginners; I remember a few years ago when the K200D came out, it made a laughing stock of all the other beginner DSLRs on the market with it's weather sealing and cross-type AF points galore. (At least, on paper?)
