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 DSLRs with a 4/3rds sensor. 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.
Instructions and examples for using hyperfocal distances are included on the card. For more info on depth of field, click here for a Depth of Field Discussion.
