To shoot photos that are sharp from foreground to infinity, you must focus at the "hyperfocal distance" for the lens and aperture you're using.

This card gives hyperfocal data for all Olympus DSLRs. The 3.5" x 5.5" laminated cheat sheet covers the following:

• Lenses from 7mm - 70mm.
• Apertures from f/4 - f/22.
• Distances are given in feet.
