I wondered about that, but the KP has a higher pixel density than the K-50, yet has lower noise. I was guessing that sensor technology was most important and that a recently produced sensor might be better.

In short... yes.

To follow up on my own post... I took a look at the Photons to Photos web site (http://www.photonstophotos.net/) and the KP at ISO 6400 has a "Photographic Dynamic Range" (their terminology) of 6.32, which is about the same as either the K-50 or K-3 at ISO 1600. The K-70 is pretty close to the KP.

After looking at this linked site, I was trying to figure out the relationship of dynamic range to noise, and don't see the connection. Can you explain this?

I am sure that my explanation will be corrected... But in this context think of photographic dynamic range as similar/related to signal to noise ratio.

From the web site: "The second test is for Photographic Dynamic Range (PDR).
This is a practical measure which incorporates all noise sources and targets a Signal to Noise Ratio (SNR) that is visually acceptable under standard viewing conditions.
PDR is the most popular measure published at PhotonsToPhotos."
