Distância hiperfocal.
Calcule a distância hiperfocal e o limite próximo nesse foco.
H = f² / (N × c) + f. The near limit is H/2. Presets are conventional circles of confusion. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
- Hyperfocal distance
- 10.466667 m
- Near limit at that focus
- 5.233333 m
H = f² / (N × c) + f. Focusing at H keeps acceptable sharpness from about H/2 to infinity for the circle of confusion you selected.
