Here is a picture of a some far away trees taken using the Olympus D580 digital camera. You can find a similar picture taken using the Canon Powershot A40 digital camera over here.

If you compare the 2 pictures taken by both cameras, you will find that the one by the D580 is sharper and has more contrast than that by the A40. I have highlighted some specific areas where you can see the differences clearly with the red, blue, and orange rectangles in the above picture. I have also cut them out and compared them side by side in the sequences of pictures below. In the pictures below, you will find that the ones by Olympus D580 is sharper and has more details than the ones by Canon A40.

If you look at the parts highlighted by the red circles in the region of the red rectangles, you will find that that part is especially blur for the A40 whereas the D580 picture shows more contrast and details. Actually, that part of the leaves is very dense. This shows that the pictures taken by D580 is truly of good quality.

However, if you look at the region marked by the orange rectangle, you will find that the tree is very noisy even though it is sharp for the Olympus D580 picture. This is shows that although the D580 tries to introduce more details and contrast to its pictures, sometimes it may unintentionally add more noise to the picture.
