You should always focus with the wides aperture possible since that\'ll be the narrowest point of focus. Stop down afterwards.

However! Some lenses do have focus shift issues most notably that I can think of is the modern Zeiss 50mm F1.4. Something to be aware of and you can easily test for in your lenses.

There\'s no real downside to focusing stopped down except maybe in low light where the LCD/VF digital gain will make the preview too grainy. Focusing stopped down does increase the \"play\" of what\'s in focus so maybe you wont nail the DOF center exactly but you\'ll still get what you want in focus and you can always view the LCD/VF to see the full DOF and alter if necessary to get the desired foreground/background DOF balance.

I find focusing wide-open and stopping down doesn\'t work well because the act of having to move the aperture ring is enough to shift the camera plane and move your focus point, esp for close-range subjects handheld.
