How many shots can one get on the 450d battery?
Depends from so many factors:
- if u use Live View
- if u are using flash
- if u are using autofocus a lot
- if u shoot REALLY long exposure times
- if u check the pictures long on LCD after the shoot
and finally we are talking about an old camera with probably old batteries..
without abusing flash/liveview, after around 200 shots i got still enough battery.
