I've been looking into getting a new camera lately and have been considering getting a Pentax K5 11s. The price has gone down lately and I just can't afford to get the K3. Anyone have the pleasure of shooting with this?
I have the K5 iis and love it. It has everything good about the Pentax line -- rugged, great interface, superb jpg processor, top-flight ergonomics, etc. Like all Pentax dslr's, other than the new KS2, it lacks an articulating or tilting lcd. (The older I get, the more attractive this feature gets. I don't like getting on the ground to compose through the viewfinder (optical viewfinder is excellent, btw) for those special shots (and getting up again is even more trouble!)
The big issue, though, is the absence of an anti-aliasing filter, which was deliberately removed on the 5iis in order to sharpen the image up. The K5 and the K5 ii both have the anti-aliasing filter in place. The K3, I believe, lets the user select or de-select this feature through use of a simulator.
Whereas the absence of the filter does arguably make the image sharper, it also increases the risk of getting moire, which can turn up in the darndest places if you're not careful.
Take a look at this web page for a technical explanation and a really good example of the real-world consequences of moire where you might not expect it.

If this kind of thing bothers you, it might be better to look for the Pentax K5ii (without the "s"). The price is even better (though not by much).
Either way, I'll bet you'll be happy. I'm a pixel peeper and I love blowing my images up 200 to 400% and marvelling at how good they look, even at ISO 1600.
