So why now is the camera producing such excellent results, could it be that sensors don’t perform properly when brand new? My Fuji's S9600 and S602 were also a disappointment to start with but with no in camera changes making any difference they both improved with use.

This is one of the most astonishing comments regarding photography I have ever come across. ....
In the audiophile community there is the well established theory of 'burning in' various componants, the speakers and amps for example.
There is the famous 'musicality' debate about Linn Sondek turntables too of course
So I wouldn't be surprised if various dslr parts including the electronics bed in and get better
Looking forward to it

I believe that was more mechanics of the deck bedding in. As for the electronics, back then, capacitor technology was average and it was often the case that the larger PSU capacitors required time to settle and reach activity saturation. Similar to cycling NiCads today. Their chemistry had large tolerences. Bass improvement was a notable case as the capacity improved in the large PSU capacitors.

Today, it's a no brainer, technology is way ahead with cap chemistry etc.

Electronics today do not bed in. If that were the case, the performance spread would be unacceptable.

Well all I can say for the poorly derided K-7 is that I upgraded from a K10 and the quality of my images improved at the same time. I think this was mainly due to the improved viewfinder and greatly improved digital display allowing me to frame shots better. I remember being impressed with the speed improvements and reduced noise also. The only complaints I had at the time were the changes to memory card slot and the spot focus control. I am still generally quite happy with it although I must admit to a tinge of jealousy to all those K5 owners. I do have one current gripe and that is since loading the latest firmware lenses have to hunt more when focusing close up to the lens and on high key subjects.

My thoughts are, with current digital cameras, the users "burn in". ie, we learn how to use the bloody things to their greatest advantage, subconsciouscly(do I win the spelling bee?).

I was being slightly tongue in cheek
but not convinced totally you are right.
I wonder if the electrons trucking along from photosites
don't make a sweeter path over time, lower the friction and give me less noise

Yes I am now totally convinced my early poor results were down to the impatient man behind the view finder. I am getting better and better photos. Thanks for the tolerance of all contributors. Im not sure how to link an image to a Forum post and hope the link below to an image I am proud of will work. I tweaked it in Photoshop Elements Cropping and fine tuning Highlights/Shadows/Sharpness.

Look at the top of the Your Photos section and the top posts explain how to post images in the forum.

Most people upload images from Photobucket or Flickr rather than from the site gallery. I believe the site gallery was to show off your best work, although I could be way off on that one. To display your images from the pentaxuser gallery, click on the image in the gallery so that is is displayed in its large format, then right-hand click on the image, if you have internet explorer select "copy url" or in firefox select "copy image location", then create your subject post, select the image button and then past the link you have copied between the two "[img]" tags. It is always worthwhile previewing the image just to make sure that all is well. Hope this helps and makes sense.
