[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Is there a specific convention that Leica follows when placing DOF markings on lenses? I'm not entirely clear on which markings refer to which apertures, particularly for the larger apertures. For example, what is the correspondence between the lines on the Summicron-M 1:2/35 ASPH and the apertures? Some of the lines don't appear to be marked, but it doesn't appear to be something as simple as leaving half-stops unmarked or something like that. For the smaller apertures, where lines are further apart, the intent of each line is more obvious.
