I'd better let this go as I am out of my depth on the technical part of it. All I know is there are things slower and faster to charge than two minutes and that I am a tech myself and bullshit has never been more than a last resort for me. But I'm not much of a faith discusser. Ecke -- PDML

- not every perceived failure necessarily is one. SDM motors hold a charge which depletes after prolonged (months) non-use. Once discharged, the lens will no longer focus. The charge takes up to two minutes to rebuild, i.e. the lens needs to be left alone for that time while connected to a
