D2X vs EOS: Depth of Field—D2X |

 |
 |
 |
 |
 |
Sharpness begins to decline at f11 due to diffraction, worsens at f16, and seriously degrades the image at f22. |

Peak sharpness is reached by f8, then contrast begins to decline at f11, and by f22, both contrast and sharpness suffer. |

Peak sharpness is reached at f16, a balance between depth of field and the effects of diffraction. f11 is close, and might be preferable to preserve foreground sharpness. |

Peak sharpness is reached at f22 because the benefits of the increased depth of field outweigh the image degradation due to diffraction. While f22 is helpful for the background, it will seriously degrade the sharpness near the plane of focus. |
