Just beware that some firms, like Panasonic, are locking their firmware
so that you can only use "genuine" Panasonic batteries and not the often
better aftermarket alternatives. That's OK to start with, but when you
decide you want a spare battery to go camping with you find they screw
you right-royally.


they try, not very successfully though it seems.

Our new Panny TZ10 is has such batteries, but you can get 3rd party
batteries that work fine in it


Jolly good - nice to know.
