Pressing the shutter button halfway and activating the autofocus will still consume
battery power even if no pictures are taken.
Since field conditions may differ, the actual number of rolls may be less than the

Pressing the shutter button halfway for prolonged periods or frequent playing with
the autofocus without taking any pictures will lower the number of rolls that can be
taken.
