There I was waiting a field for a steam loco to pass, for an unrepeatable shot (my grandad used to drive it and it is unlikely to ever be back on a line near me). D5200 on a tripod. Cable release. 18-105mm Nikkor VR with VR switched off. S mode at 1/500th set. Continuous (L) shooting mode. Pre focused and switched to manual focus, test shots with electric trains all nice and crisp. Steam train goes through, take a burst of 7 using the cable release.
when I review the pics they are out of focus completely, not a slight shift, no part is in focus at all.
When end I recheck the previous test burst of an electric train, the first 6 are sharp, and the 7th shows the same out of focus characteristics as the steam train pics. So it went out of focus mid burst and stayed like that for the next burst as it was on manual focus. I never touched the camera as I was using the cable release.
I can't work out why it went out of focus. Does anyone have any ideas? Many thanks. Ray
