Hyperfocal Distance Calculator — Maximum Sharpness Range
Find the focus distance that maximises depth of field from the nearest sharp point to infinity.
Determines circle of confusion
How We Calculate This
The hyperfocal distance formula is:
H = f² / (N × c) + f
Where f = focal length (mm), N = f-number, c = circle of confusion (mm). When you focus at H, everything from H/2 to infinity is acceptably sharp.
Example: 24mm at f/11, full frame (c=0.029mm): H = 576/(11×0.029) + 24 = 1829mm = 1.83m. Near sharp limit = 0.91m.
