    Default Lenses (Push Pull & Manual Overide)

    Hi fellow CSer

    I came across an ad in BNS that described the 80-200 f2.8 lens as "push pull" type.
    What's this? Is it better than conventional type?

    The other question is, why do photographer want to "manual overide" when he is already auto-focusing.

    Does it mean sharper pics?

    Regards
    Cichlid

    the "push pull" of 80-200 f2.8 (sld be a nikkor) meant that you push/pull instead of turn to zoom in/out not focus...

    as for manual override, it could be because maybe the photog wanted to change his focus without use AF or switch back to manual focus...

    AF does not guarantee that the it will always AF on the point you want. So that is where manual override comes in, AF to the closest point and adjust to when you want.
