To shoot landscape photos that are sharp from foreground to infinity, you must focus at the "hyperfocal distance" for the focal length and aperture you're using.
This 3.5" x 5.5" laminated card gives hyperfocal data for cameras with 4/3rds sensors.
- 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.
