What's in my Camera Bag?

There are some small but very important things in my camera bag. Starting off I have my camera of course, it is a Fuji X-T30. Next to that I have 3 extra batteries in a charging case so that I never have to worry about running out of charge. And I also have a longer lens incase it is a better fit for the shot. 

In the side pockets I have lens cloths to make sure the lens is always clean. I have extra SD card in case the current one becomes full. And lastly, I have a flash drive to quickly transfer footage.

What is your camera bag must have?
