5.6 MB JPEG (4032 x 3024)

Let's start by comparing the K-x to one of its closest rivals, the Canon EOS 500D. As so often with current DSLRs the tone curves and color response on these two cameras are remarkably similar. Both cameras also offer excellent sharpness on a pixel level with the EOS 500D, due to its slightly higher nominal resolution, producing marginally more detail. That said, we're not talking about the kind of difference that you'll see at normal enlargement sizes.

Overall at base ISO, with default settings and the right lens the Pentax K-x produces output that shows good detail out of the box. For JPEG shooters there's not really a need to play with the parameters. At default settings the images show a natural tonal and color range and good pixel-level sharpness without any sharpening artifacts.
