What would you take to a party? I'm not talking about a paid gig, just an informal birthday party in the garage and yard. I'm off to one tonight and will take the XZ, but thought I might also take the K-5 with one prime lens (35/43/50?). I'm hoping to get some decent candids. Maybe I should consider the GRD or X100 instead? Just curious about what (if anything) others do.
