Originally posted by RioRico The DPI field in the EXIF data is for scanners, not cameras. 72 DPI is filled in as a default for cameras. The pixel density of your K7's sensor is much much greater, somewhere around 6 mpx per square centimeter. The DPI number you see is only meaningful when you print. I'm sure Ira will expand fully on this when he finishes eating. Don't worry -- you don't have a lo-res camera!
Just found another article in the forum

If this is the case, and there is nothing wrong with my K7 - you can stop replying to this thread ( after confirnation) and sorry I did not found that thread before posting my question
