a9 battery life

I just completed a series of shots with the a9 over 3 days:

  • Electronic shutter (1/400 - 1/2500 seconds)
  • Continuous AF, medium spot
  • Continuous high drive speed (20 fps)
  • Sony 100-400 G lens
  • Sony 1.4x TC
  • OSS and IBIS off
  • EVF, standard

I made about 7500 exposures. The battery was fully charged at the beginning. At the end, it was down to 42%. I did not chimp.

Pretty impressive.
