Hi Tariye.
The only cameras we use here are the older EX1 models.
I’ve just taken a look on the Sony (UK) site and the latest version for the EX1R is v1.30 dated 18th May 2012, the same date/version as the EX1 version.
However, I don’t know whether the two are exactly the same.
If you’re already on a later version of firmware (say 1.20 or higher) then I think you should be able to go straight to the EX1R v1.30.
You should be able to download that version straight from Sony.
If not let me know and I can add the EX1R version to my dropbox folder.
I don’t have any previous versions for the EX1R though.
Regards,
Julian.
