Strongly suggest you protect yourself (and your camera) from damage. Most especially your eyes.
If you need to trash the useless Panasonic, so what.
Maybe do a quick upgrade to Canon, Nikon, Sony, Fuji, Leica, or Olympus. Your overall quality of photography will be improved in the future.
If you want protection at this time, try welders glass of ND 16 to ND 19. If you can see the sun through the glass, then it is safe for both your eyes and camera. I have used a ND 18 welders glass for all day viewing and all day camera protection for two total eclipses. Unless you use a camera filter of ND 16.5 stops or more (not the NDs of 1 to 3 stops used for making silky waterfalls), your camera will very quickly become "toast" and useless. Once you burn the camera's sensor, the back screen of a mirrorless is useless for viewing. Thousand Oaks sells filters for cameras and eyes. And that is the one other safety point.
If you fail to cut out the UV rays, your permanent eye damage will occur within 24 hours. There are always some ignorant people that have eye damage with every total eclipse after not following proper eye safety. At this late a time, welders glass may be your best bet. It will stop the high light intensity and UV rays of welding as well as the light and UV rays of the sun.
And one more bit of information: Once the moon covers the sun disc totally (totality), no eye protection will be needed for one's eyes or camera. Your will have only 3 or 4 minutes of totality so use them wisely.
