Frequently Asked Questions (FAQ)

• How do you find the diameter of aperture?

• To find the aperture diameter use the formula: D = F/N. where F is the focal length and N is the f-number.

• What is aperture diameter?

• The aperture diameter is the diameter of a hole or an opening through which light travels.

• What is the formula for aperture area?

• To calculate the aperture area use the formula A = π (D / 2)², where D is the aperture diameter (mm), or the formula A = π (n/ (2 * f))², where n is the focal length (mm) and f is the f-number.

• Is lower f aperture better?

• The lower the f-stop number, the wider the aperture letting more light through, resulting in a brighter image but also in a shallower depth of field.
