Originally posted by TomTextura Between the two I'd say that the K-5 is the better camera as a whole. The K-30 brings updated AF and video to the table but after that it comes up short on a few features found on the K-5 that I value. That's not to say that the K-30 isn't going to be a great camera it's just that the K-5 has better physical controls, full metal body, top LCD, and 14 bit color depth that the K-30 doesn't have. Past that they are very similar.
IMO, it will all depend on the K-30's AF, specifically the AF accuracy in low-level tungsten light. If that is no longer a bugaboo, and the AF is both faster and more sophisticated, I'd give it the edge over the K-5 in general purpose usage. But if I were doing primarily studio or landscape work, I'd definitely go for the K-5 because of the 14 bit color depth.
Still, the K-x is the best Pentax ever!
