400mm four-photo sequence near Rogers Crossing

The former Maine Central Mountain Division crests a rise just east of  Bartlett near Rogers Crossing (where the railroad crosses Route 302 west of the Attitash Ski area).

Friday, I set up here with my Canon EOS 7D fitted with a 100-400mm telephoto zoom lens to capture a Conway Scenic work extra west led by GP35 216.

The extreme visual compression afforded by this lens exaggerates the grade profile of the line to show the effect of this rise.

This sequence of images is intended to show the train climbing the grade.  

I selected my focus point manually and initiated the camera’s autofocus independently of the shutter release in order to control the focus to my satisfaction. This separate focus-control is among the features of the Canon EOS 7D.
