I hate it I know roughly what it is but I don't know if it is necessary. Is it necessary for AF? Are there any technical or economic reasons why there aren't any (?) AF lenses with direct focus? If there are compelling reasons to keep focus by wire, is it possible to make it more like direct focus? For example, I know there some lenses with hard stops. Why don't we see this in ALL lenses? Also, I hate it when you trying to focus and you gone just past and then you have to make large adjustments to go back again. Can this be improved or is it part of the deal? Is it just a lack of demand and manufactors just keep churning out them because they think we all love it?
