Thanks to the rain at yesterday's launch, it died thanks to being soaking wet - so I left it overnight to dry out (with the lense still extended as it died moments after taking my last photo). Come to try it this morning - still wouldn't turn it on. So, put it back down and went to bed for a bit. Meanwhile my grandma gave it a few goes with the hairdryer. However, when it finally did turn on, the lense zoom retracted and then jammed.
So, that's £200+ quid of my as-yet-non-existence wages gone before I've even got them
