Digital correspondence on the focus ring of Leica Q lens

The outermost circle of the lens is marked with yellow A and white characters 1.7, 2, 2.8, 4, 5.6, etc. A that represents the size of the aperture. Rotate the aperture ring to align these numbers with the white point in front, indicating the current aperture value.

0.6, 0.7 and 0.8 in the yellow label behind represent the focal length of normal photography, that is to say, the nearest focus distance in normal mode is 60CM, and the farthest is infinity. Leave it alone in automatic mode, and turn the focus ring in manual mode. These numbers indicate the distance to the focal point of the lens, and the white characters behind them represent the focal length in close-up mode, that is, close-up mode. Many white lines, such as 4, 8, 1 1, 16, are vertical lines with symmetrical sides, all of which are Jing Shenbiao. The digital part represents the aperture value, and the white line between the left and right same numbers is the depth of field, and the position just corresponds to the focal length number on the focus ring. For example, if the aperture is F4, look at the white lines corresponding to the two numbers 4 on the left and right of Jing Shenbiao, and the number on the focus ring between the two white lines is the number of depth of field, which means that the scene shot in this focal length is clear.
