Where can I find out if a firmware update is available for my camera or camcorder?

Information about the availability of firmware updates can be found under each product Downloads section.

If a firmware update is available, there will be steps on how to install the firmware for your product and also instructions for how to check the firmware version.

When you cannot find a firmware update listed under the Downloads section, it just means that Sony is currently not offering a newer firmware.   

You can stay updated for future firmware releases by downloading and bookmarking your product on the Support By Sony mobile app.
