I bought this camera for a Christmas gift but it did a bad job, because only 20 days after the purchase the zoom get clogged.I'm very dissapointed by this fact, and more by the fact that the guarrantie does not cover this faliure in [international city].The pictures are excellent but I think this camera was a very bad expense.
