Finally, a reason to use the second memory card slot in the GH5s.
"We want really nice, big, juicy raw files of our speakers, the panels, the breakouts and all the rest of our corporate event stuff for the three days of the conference but we also want to be able to upload ample selections of images in almost real time in order to share them on our varied social media accounts (Facebook, Instagram, Twitter, etc.). So, we want you to also be able to deliver small (1,000 pixel) jpegs from each session to our social media guy ---- who is in another city. The best possible scenario would be to shoot a session until you know you have good stuff and then to head to the media room to upload the images while the session is still.....in session."
I read the manual for the GH5 and found that I could customize how I use the card slots. I have identical 128GB V60 cards in every SD card slot. The #1 card is set to receive raw files while the #2 card slot is set up to receive much smaller Jpegs and video files.
I pull the #2 card out of the camera once I feel a session is well covered, stick it in my laptop and upload all the new Jpeg files to a Smugmug Gallery dedicated to my client's event.
The social media guy checks the gallery for new stuff and incorporates the images into the social feed.
Finally, a rational, real world reason for the existence of dual SD card slots on modern, reliable cameras!
Redundant back up? Naw, this is not rocket surgery...
