V-Log Filmmaker Upgrade SFU2 for LUMIX S1 Installation Procedure

Photo Moment - August 01, 2019

The Panasonic LUMIX S1 V-Log Filmmakers Upgrade (SFU2) is now shipping. Here's how to install it and unlock the full potential of your LUMIX S1! The upgrade is simply a code that is delivered physically (no, not digitally) which you use to unlock features on your camera that were installed in the v1.2 firmware update. 

How to get SFU2

If you're reading this before August 2019…

If you purchased your LUMIX S1 in the month of August 2019, then the code should have come with the camera for free. If it did not, go back to your dealer and ask for it.

If you bought the camera before the SFU2 update was released, it is available for free to all existing LUMIX S1 owners until August 31, 2019! Your dealer has the codes and will distribute them to you.

  • B&H has sent emails to all customers and will send you the codes directly. If you bought from B&H but haven't heard from them yet… reach out.
  • Adorama is sending the codes directly. If you don't receive your code soon… reach out.
  • Amazon is sending emails at the end of July to all customers to redeem the code on for free. If you don't hear from them soon… reach out.
  • For all other dealers, if they haven't called you, then you should… you got it… reach out. 

If you're reading this after August 2019…

Then I'm afraid you don't get it for free, but you can still purchase it for $200. Get it here.

How to install SFU2

First off, you have to have already installed the firmware update v1.2 on your LUMIX S1. This SFU2 is simply an unlock procedure to access the features already installed by that update. If you haven't don that yet, I have instructions right here. Go do that first, them come back.
