Remarks: Please be aware that calculating the f-number by dividing the guide number by the
distance will not result in correct f-numbers when the distance is shorter than approx. 1 meter.
This calculation requires that the size of the light source is very small compared with the
distance. This condition is not met at short distances. Therefore we recommend to use the TTL
mode at short distances instead of manual mode with calculation of the f-number.
