One last bit of advice: The film will drift slightly over time, but not by much. If you don’t want to see frame lines come into view, I would suggest on the Frame Adjust feature, moving the W function (zooms in or out) to zoom in 1 or 2 more stops–it cuts a little bit of the picture, but it gives the frame a little wiggle room too.
