Just bought the RX100 and very pleased - except - I also have a Nex6 and the filenames are the same format so when importing (I use Aperture) files with the same name get rejected!
Is there a way of chaging the filename format? Aperture will let me change the version name but not as far as I can see the actual filename. All I need is a prefix e.g. RX100 DSCxxxxxxxxxx.
