@heie - one last thing. Do you notice better AF in low light. The k20d just doesn't cut it, and the k01 isn't dramatically better. I know that the k5ii/s is the way to go for low light focusing, but just wondering how you find the K30 in low light vis-a-vis the K5 classic. Thanks again. I was considering a used k5, but now am leaning towards a k30.
You sure just one last thing?

I haven't used the K-20d, but the K-30 is pretty good with low light focusing. I just did a test in my very dark room with the K-30 and K-5IIs with the same lens (DA 18-135 WR) at 18mm. The K-5 IIs doesn't hunt, but it wasn't fast in any regard - much slower than daylight focusing (which is damn near instantaneous - K-30 as well with the 18-135). What I found interesting though was that the K-5IIs did not turn on the AF assist light (I had to check just to make sure it was actually enabled), yet the K-30 did. With the AF assist light (green on both in case you are curious), the K-30 was very decisive, something I found interesting especially considering the beam was on the wall about 4 meters away. I honestly was not expecting it to lock at that distance, but it did.

At 135mm (which means the aperture went from f/3.5 at 18mm to f/5.6 at the tele end - significantly less light), the K-5IIs hunted, but still refused to turn on its AF assist light. Odd, indeed. The K-30 obviously used its AF assist. Both lenses locked focus when I placed the center AF point (which I used the entire time) over something of high contrast (i.e. a black picture on a white wall). Otherwise, they both weren't able to lock. Like I said, it is dark.

EDIT: hmmm, it seems that the AF light wasn't going on because it was in AF-C mode, not AF-S. Turning it back to AF-S yielded the AF assist light on the K-5 IIs, and it helped locked significantly faster than without the light. Without the light, the K-5 IIs wins handily, but with on both, they seem to focus about on par - the K-5 IIs maybe a tad more decisive.

Hope this helps

-Heie

Thanks again. Sounds like the K30's AF does well even in low light and I'm guessing better than the K-5 classic. Interesting info about the light not going on in AF.C as I often use it along with back button focusing.

No AF light with AF-C is logical if you think about it. Unless you like photos of green blobs

Even the K-30 is a bit reluctant to turn on the assist light. I wish there were menu options for adjusting the light level it comes on at. That would be really handy.

I kept my K30 and sold my original K-5 to ugrade to K5 IIS. After comparing K30 and K5 IIS images. I decided not to upgrade. The K30 images is just awesome even when comparing to cameras like Nikon D4 and Canon 5D III...

So, it sounds like you see a noticeable improvement in sharpness from the original K5 to the K30.

I bought a K-30 body last night now that the price has dropped below $500 (Amazon). The sharper imaging and slightly better auto-focus performance over the K-5 seem to be real. Plus I'm one of those who prefers having the AA-battery power option. Months down the road, when the price of the K-5IIs body comes down further, it may be my K5 that goes on the market, not the K-30.
