[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]This petition has been presented previously to Leica several times, 3 or 4 times now, by other users and user groups. ?Leica has turned this option down on the grounds that users may forget to change the settings when they change lenses and get potentially detrimental results. ? Many feel this is a foolish reason as Leica users are smart enough and ready to make these adjustments. ?On the other hand, I think they have a good point as many users have complained about having to go into the menu to make exposure adjustments, such as EV corrections and ISO changes. ?So I can see many operators forget to make the proper adjustments as they are too lazy to make other adjustments. ?Personally, I do not see another petition on this subject doing any more good than the previous petitions on the subject.
