Re: Back Button Focus

Shooting locos at 60-70mph will be a bit tricky for most people, it may be easier if they are coming towards you as opposed to across the field of view. I think you should certainly try a faster shutter speed.

70mph is about 103 feet per second so according to my dodgy calculations during an exposure of 1/640 the loco would have moved almost 2 inches.

if the loco is crossing your field then panning is almost certainly necessary and although you don't mention which lens you are using if it has IS then this might help to avoid any camera shake.
