Originally posted by aleonx3 The k10D is more like D200 although they are share the same sensor different engine rather than the D80; there is no scene mode on the k10D. However, pricewise, the k10D which is no longer available would still be cheaper than the D80.
The weather sealing of the K10D makes it "more like D200", but then the same thing can be said about the K200D because it too has weather sealing. Obviously, weather sealing is no longer what differentiate pro or semi-pro models from other market segments. It is true that the K10D lacks scene mode, so it therefore must be above the competitions semi-pro models since the semi-pro models from the competition has more consumer friendly automodes than Pentax has... I don't see the lack of scene mode as a proof of the K10D belonging to the D200 market segment, especially not when it costed so little. So, again, from the buyers perspective it belongs to the same market segment as the D80 because the sales price was similar, or even below. And those who do bought the D200 could say the camera used a more expensive version of the sensor (4 channels) that made continous shooting so much faster, and therefore this means it is in a higher market segment than the K10D was.
D300 and A700 are more equipped than the K20D, and yes they cost more as a result. Even the new Nikon D90 is more equipped than the K20D, but it is true it lacks weather sealing and the fine build quality (but as the K200D has professional build quality in an entry level body, this alone is not enough to call it semi-pro or pro).
So on the market, in the eyes of the buyers, the K20D and D90 competes.
When they enter the shop to try out different models, and they try out the D90 and then ask "what other models can you offer me in this price bracket" I'm pretty confident that the sales person will show the K20D, "here, this one is similar priced".
When a customer looks for the D300 and asks for other similar priced models, the sales person is more unlikely to bring out the K20D... So in the eyes of the customer, K20D competes against the D90 and the K10D competed against the D80. I know many that were considering the D80 bought the K10D. We have had many D80 or K10D-threads. Not so many D200 or K10D-threads. Probably because those who wanted the extra speed of the D200 never considered the K10D.
