Originally posted by RiceHigh You might not have made the wrong choice, you just get what you paid. Especially when you get more features as listed on paper for the K10D, the actual performance inside the camera must have some compromises. Pentax have to sell their cameras with some profit margins and as such they have to cut corners which are not so obvious, haven't they? Enough said.
Well, a direct answer to your question is just: YES. I'm afraid all the issues you have mentioned are existent when it is compared to other cameras (or even including the K100D regarding noise and jpeg sharpness). Here are some of the documented evidence for other end-users have reported or what some reviewers found, for the issues and reported problems of the K10D:
RiceHigh's Pentax Blog: K10D
Do you need publicity for your blog so bad that you must link to it every time? Not enough hits?
You should actually put some disclaimer somewhere on the front page that your blog does not reflect your own use of the cameras and lenses you mention but is just a collection of negative internet posts and your comments and guesses as to what are the problems with Pentax.
Anyway, a blog on photography equipment without any actual pictures should look VERY suspicious to any curious onlooker.
I also use a Canon 30D which is the equivalent camera of the K10 in the Canon lineup, the 30D has some better features (high iso noise and AF tracking being the most prominent), the K10 has some better features (controls and SR are the first that comes to my mind) but even these are pretty minor and their importance in REAL use should be related to their original objective: taking pictures.
It's what your blog lacks: perspective, what separates trash-tabloids from information.
I posted a straight jpeg somewhere in this thread. Maybe it's not a very good picture (a snapshot of one of my loved ones) but I believe it's pretty sharp, the AF was FAST and precise under the relatively dim tungsten light with a f5.6 max aperture lens and it's ISO 800 without objectionable noise. But why should I even care?
It's a picture. It's what cameras are for.
The picture suits me: I keep the camera, if not, I sell the camera and get some other model.
Ask yourself: how do people manage to get acceptable pictures from such a flawed gear?
But don't worry, continue promoting your little blog here and there, you might succeed in turning one or two unexperienced photographer from Pentax but it's really pretty ridiculous.
I would advise you to take some pictures (with whatever gear) and share them with us so that we could engage in more constructive discussions about our common(?) passion/hobby but I have the feeling it's no use.
You don't really care about pictures, only gear and, somehow, I feel sad for you.
