Zeiss Formula

The Zeiss formula is a supposed formula for computing a circle of confusion criterion for depth-of-field calculations.

The Zeiss formula states that the maximum acceptable diameter of the circle of confusion equals the diagonal length of the image sensor format divided by 1,730.

Formula

QuantityVariable[Subscript["d", "CoC"], "Length"] == QuantityVariable["d", "Length"]/1730

symbol description physical quantity
dCoC maximum acceptable diameter of circle of confusion "Length"
d diagonal length of image sensor format "Length"
