I love my K10, should I jump to a K20?

The title pretty much says it, but I have been thinking of jumping from my K10 to a K20. The K20 has a few things that I would love to have, like better high ISO performance and the PC socket. I can't afford to keep both, so if anything, what will I miss from my K10? Can I make the lower ISO images from the K20 look similar to what I get from the K10? I read somewhere that the images from the K20 have a different look to them. How much better is the AF and the IQ?

I could not tell the difference, honestly.

K20D has forced dark-frame subtraction for all exposures longer than 8 seconds, which means the K10D may be more suitable for long exposures, but you can use debug mode on the K20D to turn off the DFS (the resulting image is fabulously noisy though).

K20D has the trick Live View (pretty damn useless, IMO, now that I've tried the LV on the same-generation Canon 40D) and, more useful, individual AF adjustments for up to 20 AF lenses. Very useful for me as my 16-45mm is way out of whack.

IQ is about the same given it has 50% more pixels -- down to technique (e.g. stop down your lens.. that sort of thing). AF speed, can't tell the difference. The newest firmware 1.04 "may" have improved the AF speed vis-a-vis 1.03 and older, but I can't really quantify it. The K10D may be cleaner at low ISO (400 or less) due to the Sony sensor and less megapixels.

In most other regards its simply a K10D with more pixels. I couldn't really tell the difference.

In summary: I swapped my K10D for a K20D because I couldn't live with the 16-45mm being so out-of-whack (using the global AF adjustment on the K10D meant that all my other AF lenses because out-of-whack). I had gotten the 16-45mm used so could not exchange it. But that was basically the only reason for my swap. If not for that, I'd probably have stayed with the K10D.

Colour rendition is slightly different - cooler and with more troublesome noise issues when shooting in high ISO.. This synopsis may give you further insight: https://www.pentaxforums.com/forums/pentax-news-rumors/19036-my-2500-word-essay-k20d.html

I couldn't really tell a difference between the two.. both of them have not-so-good AWB so I always ended up with custom WB (via shutter/select white area)..

The thread linked to above (with the very long writeup on the benefits of the K20D) I haven't had the time to read through the whole thread, but my immediate impression is that, all those whiz-bang "improvements" didn't seem apparent to me at all. And I think the K20D has more noise than the K10D, "ISO 1600 base" and "patented sensor" and "same pixel size as the 12MP Sony" notwithstanding. Let's not forget that "12MP Sony" is the sensor in the K-x and K-r (and in the Nikon D90).

We all know where that "patented sensor" *cough* K7 *cough* went...

I've been in the same position. I've looked very carefully at the changes introduced by the K20d and decided it was not worth moving from K10 to K20, for these reasons: high iso improvement is only one stop i.e. usuable high iso on my model is 400 iso - 800 iso is just too noisy to be of anything but emergency use. On the K20, 800 iso is usuable but 1600 is noisy - I know some people have published smooth 1600iso pix with the K20 but they take the shots in relatively good light - I'm talking about really low light where high iso sensitivty is essential.

The other new features are just that, features and dont make you a better photographer.

So I jumped to a K-X and kept the K10 - I use both - the K-X is my daily camera and the k10 is my 'studio' camera i.e. special shots where I can use low iso and focus slowly and carefully. I find the back mounted infrared port on the K10 to be very useful and the remote socket likewise, which the K-X does not have.

The K20D's ISO100 is also noisier than the K10D's if you pixel peep...

K10D to K20D is almost the same story as EOS 40D to 50D:

What do you get in the 50D that isn't in the 40D? mostly, it's micro AF adjustment for many lenses, and more pixels! :-)

My thought on this jump from K10D to K20D would be the extra pixels (good or bad not sure) and a few other improvements; which is not a whole lot of improvement compare to a K-7 jump, which has more points for multi-segment metering (improve accuracy and WB) and focus assist lamp. Of course, if you prefer the ergonomics of K10D (slightly bigger body) then K20D would be a good choice.

Thanks guys, it sounds like you may have talked me out of a mistake! Now I'm thinking k-x, but that is a topic for another thread!

I went from the K10D to the Kx and never looked back. It is a lot of camera for the money.

two major drawbacks of the K-x are no WR, and no AF point illumination.

i've been told the K-r is a better choice due to the almost 1 megapixel screen and AF illumination (even though the sensors are almost the same).

The WR really isn't much of an issue for me, and I always set my AF to center point only. The only real bummer for me is the step down to a pentamirror, but it's not a deal breaker for me.

I'd suggest keeping your eyes open in the forum marketplace for a good used K-7. It pretty much trumps the K10D in every possible way.
