Depth of Field Calculator
|
This calculator is a series of DEPTH OF FIELD SCALES for various lenses. To use the guide:
* Locate the DOF scale for the lens you're interested in.
* Set the DISTANCE scale on the
white slider to the FOCUS POINT (on the middle of the APERTURE scale).
* Where the distance scale matches the aperture lines shows the range of sharp focus at each aperture.
Side 1 - Examples on the 35mm lens scale
A) A 35mm lens set at f/16 and focused at 10 feet produces a "sharp" photo of objects from 5 feet to infinity.
B) A 35mm lens set at f/8 and focused at 10 feet produces a "sharp" photo of objects from 6.7 feet to 20 feet.

Side 2 - Examples
- A 105mm lens set at f/16 and focused at 90 ft (see 105mm - Far scale) produces a "sharp" photo of objects from 45 ft to infinity.
- A 105mm lens set at f/16 and focused at 6.5 ft (see 105mm - Near scale) produces a "sharp" photo of objects from 6.1 ft to 7 ft.
