Telephoto to Wide perspectives of the same trains
2
The EF-M 18-150mm IS STM makes a great all-in-one lens for moving train photography when there is little to no time to change lenses!
Here's a sharp sequence of a train pulled by CSX locomotive 6280, moving South towards me on the Clearwater subdivision track in Tampa at 10-15 mph, taken at six progressively shorter focal lengths from 150mm to 18mm over a span of 19 seconds from the same spot.
Quite a range of perspectives: in the first shot at 150mm, the I-4 bridge looms above the train and the train cars are large and compressed --- in the last shot at 18mm the I-4 bridge appears small and far away, and the locomotive stretched out. I tried to keep the front of the locomotive about the same size in each shot.
The most obvious effect is the size of the crossing lights to the right get smaller in each photo.

A 3-image sequence of the Silver Star Amtrak train, just after leaving Tampa's Union station tonight. This set ranged from 125mm to 24mm.
