Hi all, I have a Canon 450D which I use with a Sigma 150mm macro with single point autofocus- no problems. I am trying the lens on a Canon 100D. Press to focus, nice crisp view in the view finder and the familiar 'beep' - but after a second or two, the image starts to blur. Press again, focuses perfectly, then drifts again - any ideas? Thanks

Sorry for asking obvious questions but is it mounted on a tripod? If handheld, could you be moving?
