Might have been told as a joke,but you're pretty right about that,i ran out of about 600 pics in a fly-in of only 45 aircraft sitting in a space no bigger then 1 cubic km,and they were only landing,so... 1659 is not enough!
Remind taking enough Batteries with you!
At the last airshow here I ran out of power long before "EOM = end of memorycard"...
And I took well charged spare with me... Vendor-/model-specific packs could be a problem!
Cameras fed by standard-cells are in advantage then - or maybe a solar-charger
Awaiting your pictures - thanks in advance!
