Practice question · Multiple choice
A landscape photographer with a 35 mm lens wants everything from a few metres away to the horizon acceptably sharp. How does the hyperfocal distance tell them where to focus?
Hints
- The near limit is a simple fraction of the hyperfocal distance.
- The whole point is to reach infinity without wasting the near half of the range.
Show the answer
D. Focusing at the hyperfocal distance keeps half that distance to infinity acceptably sharp
Why
Focusing at the hyperfocal distance is the setting that reaches infinity while giving away as little near sharpness as possible: everything from half that distance outward is inside the circle of confusion. Focusing at infinity instead throws away the entire near half of the available range for no gain at all.
