Dear Klaus
DP just reviewed the K-5 and suggest it has a resolution of 2600 for JPEG and 2800 for Raw. I ve downloaded the files and looked at it at 200%(true pixel peeping <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='
' /> ) I think that is about right.
1.Is the difference to your findings because DP sharpen files to the optimum and you take the default of the camera?
Pentax always had a very conservative approach to sharpening and contrast( except the Pentax KX) . So wouldn´t it be fair to set the sharpening and contrast to the same level as other brands has at default. But then,what are we measuring in the end? If I take for instance a photo of the KX and the K5 I really can hardly see a difference and my guess would be most of the difference would be through settings of the camera/ photoshop. I believe people in forums arguing more about different default camera settings then sensor qualities. Which brings me to my second point.
2. Is it right to measure just black and white resolution for sensor and lenses( taking the extra work out of account <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='' /> ? Some of my cheaper Sigma lenes have a slight warm tone, does that mater? If I have a look on this compareometer

I find that many cameras can`t `see ` the red right especially on higher iso´s. Have a look at the left red fabric. Compare for instance the Oly E-5 and the Pentax K-5. Pentax does a better job of the red fabric, but Olympus shows the blue and the pink textures in more detail. So which one has the higher resolution?
All this leaves me just puzzled. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/unsure.gif' class='bbc_emoticon' alt='

I guess in the end of the day you just have to be happy with the output of the camera of your choice. In my case the Pentax K-10 which is still excellent and the Sigma SD-14 for the brilliant fabric textures) . But I would appreciate your input on my two theories.
